Yes, protein powder may trigger or worsen acne in some people, particularly whey protein users, but research does not show that every protein supplement causes breakouts.
Protein powder is common in American gyms, college fitness centers, and home workout routines. Many people in the United States use it to support muscle growth, recover after exercise, or meet daily protein needs. But some users notice new pimples after adding a protein shake to their daily routine. This raises a fair question: can a simple fitness supplement affect your skin?
The answer depends on the type of protein, your skin, your diet, and other factors. Whey protein comes from milk and has received the most attention in acne research. Some small studies have found a link between whey supplements and breakouts. However, a randomized clinical trial published in 2024 did not find a significant worsening of acne in men who took whey protein compared with those who used a non-whey supplement.
This means the link is possible, but it is not proven for everyone. If your skin changes afterstarting protein powder, you do not need to panic or give up your fitness goals. You can review the ingredients, look for other possible triggers, and consider a careful change in your protein source. This guide explains what research says and how to make a sensible choice.
How Protein Powder May Cause Acne
Protein powder may affect acne through several biological pathways, especially when the supplement contains whey. Acne develops when hair follicles become blocked by oil and dead skin cells. Bacteria and inflammation can then contribute to pimples, blackheads, whiteheads, and deeper spots.
Hormones help control the amount of oil your skin makes. Some foods and supplements may affect hormone-related signals. Whey protein is of interest because it comes from milk and contains amino acids and other bioactive components that may influence insulin and IGF-1 activity.
Insulin-like growth factor 1 is a hormone involved in growth and cell activity. It also plays a role in processes linked to skin oil production. Higher activity in these pathways may encourage conditions that support acne in people who are already prone to breakouts.
This does not mean that drinking one protein shake will automatically cause pimples. Acne has several causes, and people respond to food and supplements in different ways.
Changes in insulin activity
Whey protein can stimulate insulin release. Insulin-related signals may affect skin processes linked to oil production and acne.
IGF-1 activity
IGF-1 helps control growth and cell activity. Its signaling is also linked to sebum production and the development of acne.
Milk-related components
Whey is a dairy protein. Its relationship with acne may involve more than its total protein content.
Individual skin response
Genetics, hormones, age, and existing acne can affect whether a person notices a change after using a supplement.
What Is the Connection Between Whey and IGF-1?
IGF-1 stands for insulin-like growth factor 1. Your body makes this hormone, and it helps regulate growth and tissue development. It also interacts with pathways involved in skin oil production.
Whey protein may influence insulin and IGF-1-related signaling. This is one reason researchers have explored a possible link between whey supplements and acne. However, a possible biological pathway does not prove that a supplement will cause visible acne in a particular person.
The strength of the response can differ from one person to another. Someone with acne-prone skin may notice a change, while another person may use whey for years without seeing a clear difference.
Practical meaning
If you notice a clear pattern between whey use and breakouts, reviewing the supplement may be reasonable.
Does More Protein Mean More Acne?
Not necessarily. Eating enough protein does not automatically cause acne. Protein supports muscle repair, tissue growth, and many normal body functions.
The type of protein, the rest of your diet, and your personal response may matter more than the total number of grams. There is not enough evidence to set a protein intake limit that prevents acne in all people.
Do not cut protein from your diet just because you have pimples. A balanced diet can support both exercise and general health.
What Does Research Say About Protein Powder and Acne?
Research suggests a possible connection between whey protein supplements and acne, but the findings are not consistent. Some observational studies report more acne among whey users, while a randomized trial found no meaningful worsening in its small group of male participants.
Understanding the difference between these study types is important. An observational study can identify a pattern, but it cannot always show that one factor caused another. A randomized trial offers stronger evidence about cause and effect, although a small trial may not apply to every person.
The current evidence supports a cautious conclusion: whey protein may contribute to acne in some people, but more large and diverse studies are needed.
2024 case-control study
A study published in Dermatology Research and Practice examined 201 male teenagers and young adults in Jordan. Whey use was reported by 47% of participants with acne and 27.7% of those without acne. The association remained significant after adjustment for several factors. This finding supports a possible link but cannot prove that whey caused acne.
2024 randomized controlled trial
A study in The Journal of Dermatology followed 49 men with mild to moderate acne for six months. One group received 30 grams of whey protein daily alongside a non-whey supplement, while the comparison group received a non-whey supplement. The researchers found no significant worsening of acne in the whey group compared with the control group.
Earlier observational research
A small Brazilian study published in 2013 followed 30 young adults who used protein-calorie supplements. Researchers observed the onset or worsening of acneiform lesions. Its small sample and observational design limit the conclusions.
Why Do the Study Results Differ?
The studies did not examine exactly the same people or use the same methods. Age, sex, existing acne, supplement use, diet, and other lifestyle factors can influence the results.
The 2024 randomized trial included only 49 men who already had mild to moderate acne. It was useful for comparing changes in acne severity, but it was too small to answer every question about women, teenagers, people without acne, or long-term supplement use.
The Jordanian case-control study found a higher rate of whey use among people with acne. However, researchers cannot completely remove the effects of every difference between the two groups.
Together, these findings show why it is misleading to say that science has proved whey protein always causes acne. It is equally misleading to say that whey can never affect the skin.
What is established
Some research has found an association between whey use and acne.
What remains uncertain
The size of the risk, the people most likely to be affected, and the dose or duration that might matter are not established.
What readers should do
Look for a consistent personal pattern instead of assuming that every breakout comes from a supplement.
Which Types of Protein Powder Are More Likely to Affect Acne?
Not all protein powders have the same ingredients. Whey has received the most attention in acne research because it comes from milk. Other protein sources may be suitable alternatives, but direct research comparing their effects on acne is limited.
A plant-based powder is not guaranteed to improve your skin. It may simply remove whey and other dairy ingredients from your routine, making it easier to see whether those ingredients were relevant.
The following table compares common protein sources and what is known about their possible relationship with acne.
Whey Protein Concentrate
Whey concentrate is made by separating whey from milk and processing it into a powder. It usually contains protein along with varying amounts of lactose, fat, and other milk components.
It may be a concern for people who suspect dairy-based supplements worsen their acne. However, the presence of whey concentrate does not mean that everyone who consumes it will develop pimples.
Check the ingredient label for added milk ingredients, sweeteners, and other components. The complete formula matters when you are trying to identify a possible trigger.
Who may want to review it
People who repeatedly notice more breakouts after starting a whey concentrate supplement.
Whey Protein Isolate
Whey isolate goes through additional processing to increase its protein concentration and reduce much of its lactose and fat. It is often chosen by people who want a protein source with less lactose.
However, whey isolate is still a dairy-derived protein. Removing much of the lactose does not remove the whey proteins themselves.
If whey is the suspected acne trigger, changing from concentrate to isolate may not solve the problem. The acne research does not establish that isolate is safe from this possible effect.
Important distinction
Lower lactose content does not mean that a product is free from whey or all dairy proteins.
Casein Protein
Casein is another protein found in milk. It digests more slowly than whey and is often used as a standalone powder or in protein blends.
There is less direct evidence about casein supplements and acne than there is for whey. It would be inaccurate to claim that casein always causes acne or that it is a proven acne-free replacement.
People who suspect dairy affects their skin may wish to discuss a non-dairy option with a health professional.
Pea Protein
Pea protein comes from yellow peas. It is a popular plant-based option for people who avoid dairy or follow a vegetarian or vegan diet.
Pea protein does not contain whey or casein. This makes it a practical alternative when testing whether a dairy-based supplement is linked to breakouts.
Choose a product with a clear ingredient list and a protein amount that fits your needs. People with pea allergies should avoid it.
Soy Protein
Soy protein is made from soybeans and provides all nine essential amino acids. It can support protein intake without using dairy-based ingredients.
There is no strong clinical evidence showing that soy protein powder causes acne in most people. However, a lack of evidence is not proof that every soy product will suit every individual.
People with soy allergies should avoid soy-based supplements. Others can consider it as one of several non-dairy options.
Rice and Mixed Plant Proteins
Rice protein is made from processed rice and is another dairy-free option. Some products combine rice protein with pea protein to improve the overall amino acid profile.
These blends can help people meet their protein needs without whey. Their direct effects on acne have not been studied enough to claim that they prevent breakouts.
Check whether the powder contains added milk ingredients, high amounts of added sugar, or other components that may not suit your needs.
Can Added Sugar and Other Ingredients Cause Breakouts?
Yes, the full ingredient list deserves attention when you are trying to understand changes in your skin. Some protein powders contain added sugar, flavor blends, milk solids, and other ingredients.
The relationship between diet and acne is not limited to whey. The American Academy of Dermatology reports that foods with a high glycemic load may worsen acne in some people. These foods raise blood sugar quickly and may influence hormone-related pathways.
However, this does not mean that every sweetened protein shake will cause acne. The amount of sugar, the rest of your diet, and your individual response all matter.
Added sugar
Some flavored powders contain added sugars. A diet high in rapidly absorbed carbohydrates may contribute to acne in some people, although the effect of one shake is not established.
Milk powder and milk solids
These ingredients can add dairy components to a product. Check the label if you suspect milk-based ingredients affect your skin.
Flavoring ingredients
Chocolate, vanilla, and other flavor blends can contain several ingredients. A reaction to one specific ingredient is possible, but ordinary flavoring is not a proven general cause of acne.
Added vitamins and minerals
Some supplements contain large amounts of added nutrients. High doses of certain supplements, including vitamin B12, have been linked to acneiform eruptions in some reports.
Extra performance ingredients
Some products contain several active ingredients beyond protein. Review the full formula rather than judging a supplement by its front label.
Does Chocolate Protein Powder Cause Acne?
Chocolate protein powder does not automatically cause acne. Cocoa flavor alone has not been established as a common cause of breakouts.
The actual formula is more useful to examine. A chocolate whey powder may contain whey, sweeteners, milk ingredients, and other additives. If you suspect the product, look at all its ingredients instead of blaming chocolate alone.
You can compare the ingredient list with a plain or unflavored product, but change only one major factor at a time when possible.
Can Artificial Sweeteners Cause Acne?
There is not enough strong human evidence to say that artificial sweeteners commonly cause acne. Some people may have individual reactions or digestive symptoms from particular sweeteners, but these effects should not be confused with a proven acne link.
If you suspect a sweetener, check whether it appears in several foods or supplements you use. Avoid making broad dietary changes without a clear reason.
How to Tell If Protein Powder Is Causing Your Acne
The most useful first step is to look for a pattern between supplement use and changes in your skin. A breakout that begins after a new product may be related, but timing alone does not prove the cause.
Acne can change due to stress, hormones, sleep, skin products, medications, and other parts of your diet. A simple tracking plan can help you avoid guessing.
Do not stop prescribed acne treatment while testing a food or supplement change. Diet changes should not replace care that is already working for you.
Step 1: Record when the breakouts started
Write down when you began using the powder and when you first noticed new pimples. Include changes in acne location, such as the forehead, cheeks, chin, chest, or back.
Step 2: Check the ingredient label
Look for whey concentrate, whey isolate, casein, milk solids, added sugar, vitamins, and other active ingredients. Save a photo of the label for comparison.
Step 3: Review other recent changes
Think about new skin care products, medications, supplements, shaving habits, exercise routines, and changes in sleep or stress.
Step 4: Consider a planned change
If whey seems like a possible trigger, discuss a temporary switch to a suitable non-dairy protein source with a health professional, especially if you have dietary or medical needs.
Step 5: Track your skin over time
Use consistent lighting and take weekly photos if helpful. Record new breakouts without changing several other habits at once.
Step 6: Review the result
Look for a sustained change rather than judging your skin after one or two days. If acne does not improve, consider other causes and seek medical advice.
How Long Should You Stop Protein Powder?
There is no medically established withdrawal period for testing whether protein powder affects acne. Skin changes take time, and existing pimples may remain even after a suspected trigger is removed.
A practical observation period may last several weeks. Some people use roughly six to eight weeks to look for a pattern, but this is a personal tracking approach, not a proven diagnostic test or guaranteed treatment period.
If you see no improvement, the powder may not be the main cause. If your skin improves, that still does not prove which ingredient was responsible. Other changes during the same period could explain the difference.
Keep other habits steady
Avoid changing your cleanser, medication, diet, and supplement routine all at once if you want to understand which change matters.
Do not restart a product that caused a serious reaction
If you experienced swelling, hives, breathing problems, or another severe reaction, do not deliberately test the product again. Seek medical help.
What If Your Acne Does Not Improve?
Persistent acne does not mean that you have failed to identify the right food. Hormones, genetics, skin oil, inflammation, and clogged pores can keep causing breakouts even after a supplement change.
If your acne remains active, review your skin care routine and consider an appointment with a dermatologist. Effective acne treatment often requires topical products or prescription medication rather than diet changes alone.
Best Ways to Get Protein Without Whey
You can meet your protein needs without whey powder. A varied diet can provide protein from beans, lentils, eggs, fish, poultry, tofu, nuts, seeds, and other foods.
If you rely on shakes for convenience, a non-dairy protein powder may help you keep your routine while checking whether whey is a possible trigger. The goal is to find a source that fits your nutritional needs, not to buy the most expensive product.
A plant-based powder should be selected based on its protein content, amino acid profile, allergies, and ingredient list. No plant protein has been proven to prevent acne.
Pea protein
A dairy-free source that can provide a useful amount of protein per serving.
Soy protein
A complete plant protein that contains all nine essential amino acids.
Pea and rice blends
A combination that can provide a broader amino acid profile than some single-source plant powders.
Egg protein
An option for people who eat eggs but want to avoid dairy-based protein supplements. Avoid it if you have an egg allergy.
Whole-food protein
Beans, lentils, tofu, chicken, fish, eggs, and other foods can help meet daily protein needs without relying on a powder.
How to Choose a Protein Powder for Acne-Prone Skin
Start with the protein source. If you suspect whey, choose a clearly labeled non-dairy option rather than switching between different whey formulas.
Next, check the serving size and the amount of protein per serving. A powder should support your daily needs without forcing you to consume more protein than you need.
Look for a short, clear ingredient list. A simple formula can make it easier to identify possible triggers, although fewer ingredients do not guarantee better skin.
Finally, check the allergen statement. A product labeled plant-based may still be made in a facility that handles milk, soy, nuts, or other allergens.
Read the protein source
Check whether the powder contains whey, casein, soy, pea, rice, egg, or a blend.
Check added ingredients
Review sugar, sweeteners, vitamins, minerals, and additional performance ingredients.
Review allergy information
Check both the ingredient list and the manufacturer’s allergen statement.
Avoid unsupported skin claims
Claims such as acne-proof, hormone-free skin, or guaranteed clear skin should not replace reliable ingredient and nutrition information.
Does Protein Powder Cause Acne in Men and Women?
Protein powder may affect men and women differently, but research has not established a reliable sex-based risk. Hormonal patterns, age, genetics, and the type of acne can all influence how the skin responds.
Some research on whey and acne has focused on male teenagers and young adults. This means the findings cannot automatically be applied to every woman, older adult, or person with a different health profile.
Both men and women can experience acne related to several factors. It is better to assess personal symptoms and supplement ingredients than to assume that one sex is more likely to develop breakouts.
Protein Powder and Acne in Men
Men who lift weights may use whey supplements to support muscle growth. However, intense training routines can involve other factors that affect the skin, such as sweat, friction, tight clothing, and hormonal changes.
Acne on the shoulders, chest, and back may have several possible causes. If these areas become more affected after starting whey, reviewing the supplement is reasonable, but it should not be the only step.
Protein Powder and Acne in Women
Women can also experience acne while using whey or other protein powders. Hormonal changes during the menstrual cycle, pregnancy, and certain medical conditions may influence breakouts.
If acne appears along the jawline or chin, hormones may be one possible factor. This pattern does not prove a hormonal disorder or show that protein powder is responsible.
Women with persistent acne, irregular periods, or other concerning symptoms should discuss them with a health professional rather than relying only on supplement changes.
Can Teenagers Get Acne From Protein Powder?
Teenagers often develop acne because of normal hormonal changes during puberty. Adding a supplement can make it harder to identify which factors are involved.
The 2024 Jordanian case-control study included male teenagers and young adults and found an association between whey use and acne. However, it did not establish that whey caused acne in all teenage users.
Teenagers should discuss sports supplements with a parent or guardian and a qualified health professional. A balanced diet is usually the best starting point for meeting basic nutrition needs.
Other Reasons You May Be Getting Acne
Protein powder is only one possible factor in a breakout. Acne is a complex skin condition, and several influences can work together.
Before blaming a supplement, look at your skin care habits, hormones, medication use, and workout routine. This wider view can help you avoid unnecessary food restrictions.
Hormonal changes
Androgen hormones can increase oil production. Puberty, menstrual cycles, and some medical conditions can affect acne.
Genetics
A family history of acne may increase your chance of developing the condition.
High-glycemic eating patterns
Some research links diets rich in rapidly absorbed carbohydrates with worse acne. The effect varies between people.
Certain skin care products
Heavy or pore-clogging products may contribute to blocked pores in some people.
Sweat and friction
Tight workout clothing, sports equipment, and repeated rubbing may contribute to acne-like breakouts.
Certain medications and supplements
Some medicines and high-dose supplements can cause acne or acne-like eruptions. Review new products with a health professional.
Stress and sleep changes
Stress and poor sleep may affect acne management and can coincide with changes in exercise or eating habits.
How to Tell Acne From Other Skin Reactions
Not every bump that appears after starting a supplement is acne. Some people develop irritation, allergic reactions, or folliculitis, which is inflammation around hair follicles.
Acne often includes blackheads, whiteheads, inflamed pimples, or deeper nodules. Folliculitis may cause groups of similar-looking bumps or small pustules around hair follicles.
An itchy rash, hives, swelling, or a sudden widespread skin reaction needs a different assessment. If you are unsure what you are seeing, a dermatologist can help identify the condition.
Typical acne
May include blackheads, whiteheads, red pimples, and deeper painful lesions.
Possible folliculitis
May appear as similar small bumps or pustules centered around hair follicles.
Possible allergic reaction
May include itching, hives, swelling, or other symptoms. Breathing difficulty or throat swelling requires emergency medical care.
How to Manage Acne While Keeping Your Fitness Goals
You do not need to abandon strength training or protein-rich foods because you have acne. A better approach is to address the possible trigger while keeping your nutrition balanced.
If you suspect whey, consider a suitable alternative and track your skin. At the same time, follow a simple skin care routine and avoid habits that may irritate your skin.
The American Academy of Dermatology explains that diet changes alone are not enough to manage acne. Effective treatment often requires skin care and medication.
Use a gentle cleanser
Wash your face gently, especially after exercise. Avoid harsh scrubbing, which can irritate inflamed skin.
Shower after workouts
Remove sweat and change out of damp workout clothes when practical.
Choose non-comedogenic products
Look for skin care products labeled non-comedogenic or oil-free if heavy products seem to worsen your acne.
Avoid picking pimples
Picking and squeezing lesions can increase inflammation and raise the risk of scars.
Maintain balanced meals
Include protein, vegetables, fruit, whole grains, and healthy fats rather than following a highly restrictive diet.
Consider proven acne treatments
Depending on your skin and the severity of acne, a health professional may recommend benzoyl peroxide, topical retinoids, or other treatments.
When Should You See a Dermatologist?
See a dermatologist if your acne is painful, deep, widespread, or leaving scars. You should also seek help if over-the-counter care does not improve the condition or if breakouts are affecting your confidence and daily life.
A dermatologist can determine whether you have acne, folliculitis, or another skin condition. They can also help you choose treatment based on your age, skin type, medical history, and other needs.
Seek urgent medical care if a supplement causes serious symptoms such as breathing difficulty, throat swelling, or a severe allergic reaction. These are not ordinary acne symptoms.
Common Mistakes to Avoid
It is easy to blame every breakout on the newest product in your routine. However, acne often develops from several overlapping factors, so a rushed conclusion can lead to unnecessary changes.
Use a simple and measured approach. This can help you protect your nutrition while finding out whether a supplement is actually relevant to your skin.
Assuming all protein powders cause acne
Whey has received the most research attention, but different protein sources have different ingredients. There is no evidence that all protein powders cause breakouts.
Switching between several products at once
Changing multiple supplements makes it difficult to identify which ingredient may be involved. Test one major change at a time when possible.
Cutting out all dairy without a clear reason
The evidence on dairy and acne is not equally strong for every dairy food. Avoid unnecessary restrictions, especially if they make your diet less balanced.
Ignoring the complete ingredient list
A product may contain several ingredients beyond its main protein source. Check the entire label.
Expecting overnight results
Acne does not disappear immediately after removing a suspected trigger. Existing lesions can take time to heal.
Stopping prescribed treatment
Do not replace medical acne treatment with dietary changes without discussing it with your health professional.
Taking excessive supplements
More protein or extra vitamins do not automatically improve fitness. Excessive supplement use may create other health concerns.

Frequently Asked Questions
Q
Does protein powder cause acne in everyone?
No. Protein powder does not cause acne in everyone. Some people may notice worse breakouts after using whey, while others experience no visible skin changes.
Your hormones, genetics, diet, skin care, and supplement ingredients can all affect the result. Current research does not establish a universal acne risk for all protein powders.
Q
Does whey protein cause more acne than plant protein?
Whey protein has a stronger suspected link with acne because it comes from milk and may influence insulin and IGF-1-related pathways. Plant proteins such as pea, soy, and rice do not contain whey.
However, there are not enough direct clinical trials to prove that plant protein always causes fewer breakouts. It may be a reasonable alternative if you suspect dairy-based supplements affect your skin.
Q
Can protein shakes cause hormonal acne?
Protein shakes may influence hormonal and metabolic pathways linked to acne, particularly when they contain whey. However, there is not enough evidence to say that protein shakes directly cause hormonal acne in everyone.
Acne along the chin and jawline may have several causes. Persistent or recurring breakouts should be assessed by a dermatologist.
Q
Will my acne go away if I stop taking whey protein?
It may improve if whey is a meaningful trigger for your breakouts. However, stopping whey will not necessarily clear your skin because acne has several possible causes.
Look for changes over several weeks while keeping other habits as steady as possible. If your acne continues, seek advice about other triggers and effective treatments.
Q
Does whey protein isolate cause acne like whey concentrate?
Both are dairy-derived proteins. Whey isolate generally contains less lactose and fat than whey concentrate, but it still contains whey proteins.
There is not enough clinical evidence to show that whey isolate is less likely to affect acne than whey concentrate. People who suspect whey itself may need to consider a non-dairy alternative.
Q
Can I build muscle without protein powder?
Yes. You can build muscle without protein powder by eating enough protein from foods such as eggs, fish, chicken, tofu, beans, lentils, and dairy products that suit your needs.
Protein powder is a convenience, not a requirement. Your overall food intake, resistance training, recovery, and consistency matter.
Q
Can protein powder cause acne on the back and shoulders?
It may contribute to breakouts in some people, but back and shoulder acne can also result from hormones, genetics, sweat, friction, and other factors.
If these areas worsen after starting whey, review the supplement and your workout habits. Persistent or painful lesions deserve medical attention.
Q
Is acne from protein powder permanent?
Acne related to a possible supplement trigger is not necessarily permanent. Breakouts may improve if the relevant trigger is removed and the skin receives suitable care.
However, severe or long-lasting acne can leave scars. Do not delay treatment if you develop painful nodules or lasting marks.
Q
Should I switch to pea protein if whey causes breakouts?
Pea protein can be a practical dairy-free alternative. It supplies protein without whey or casein and can fit into many plant-based diets.
It is not a proven acne treatment, and people with pea allergies should avoid it. Check the complete ingredient list and choose a product that meets your nutritional needs.
Q
Can protein powder cause acne even if I do not drink milk?
Yes, it is possible to consume whey protein without drinking a glass of milk. Whey is a milk-derived protein that is sold separately as a supplement.
Avoiding regular milk does not mean that your diet is free from dairy proteins. Check the supplement label if you are trying to identify a possible dairy-related trigger.
✦ Wrapping Up
Conclusion
So, does protein powder cause acne? It can contribute to breakouts in some people, especially when the product contains whey protein. Research has found a possible association, and biological pathways involving insulin and IGF-1 offer a reasonable explanation. However, a small randomized trial published in 2024 did not find significant acne worsening among men who used whey for six months.
This means the relationship is not simple. Your skin may respond differently from someone else’s, and whey is not the only possible cause of acne. Hormones, genetics, diet, skin care, and other supplements can also affect your skin.
If you suspect your protein powder, check the ingredient list and consider a planned change to a suitable non-dairy source. Track your skin over several weeks instead of making several changes at once. You can still meet your protein needs through whole foods and suitable supplements.
Most importantly, do not let acne stop you from caring for your health and fitness. A balanced diet, sensible supplement choices, and proper skin care can work together. If your acne is painful, persistent, or leaving scars, a dermatologist can help you find an effective treatment.
💡 Key Takeaway
If your breakouts began after you started using whey protein, check the label, consider a suitable pea or soy protein alternative, and track your skin for six to eight weeks. Keep other habits steady and seek dermatological advice if acne persists or becomes painful.
If you’ve ever stood in the health food aisle wondering why are protein bars bad for you when the label touts 25 grams of protein, you’re not being irrational.…
