Protein Powder That Doesn’t Cause Acne

Can Protein Powder Cause Acne?

Acne is an inflammatory disorder of the skin that causes outbreaks of lesions, commonly referred to as pimples or zits.

It can present in various forms, including:

• whiteheads: closed, clogged pores that appear as small, white bumps on the skin
• blackheads: open, clogged pores that darken due to oxidation and appear as black or dark brown spots
• papules: small, red, and tender bumps that arise from inflamed hair follicles
• pustules: red, tender bumps filled with pus
• cysts: deep, painful, pus-filled lesions that can cause scarring

Acne is thought to have several causes including oily skin, clogged pores, bacteria, inflammation, and hormonal changes.

Certain medications, beauty products, behaviors, stress, and foods can trigger acne too.

Diet is actually thought to be one of the leading causes of acne (Postepy Dermatol Alergol, 2016).

It follows that protein powder can cause acne.

Why Does Protein Powder Cause Acne?

There are several reasons why protein powder can cause acne.

For starters, meta-analyses and observational studies have demonstrated a positive relationship between dairy intake and the development of acne (Clin Nutr, 2019).

This means that dairy-based proteins like whey and casein are probably not a good choice for someone with acne-prone skin.

In fact, several studies have indicated a link between whey protein supplementation and the exacerbation of acne (Dermatology, 2012).

For the record, the exact mechanisms behind this link are unclear and more research is needed.

That said, dairy has been shown to stimulate the production of insulin and insulin-like growth factor, both of which have been linked to acne development (J Dtsch Dermatol Ges, 2009).

Soy is another protein powder ingredient that might contribute hormonal acne.

The only evidence linking soy and acne is anecdotal, however.

If you think soy is causing you to break out, eliminate it from your and see what happens; if your skin clears up, you probably found your culprit.

It is worth mentioning that your acne may be related to the health of your gut microbiome – the collection of microorganisms living in your digestive tract (Life (Basel), 2022).

It is thought that altering the gut microbiome increases intestinal permeability, contributing to skin inflammation (J Clin Med, 2019), which occurs at all stages of acne development.

Increased intestinal permeability allows for toxins and bacteria to enter the bloodstream, triggering an inflammatory response throughout the body, including the skin.

You should therefore stick to gut-friendly ingredients when choosing a protein powder for acne-prone skin.

What Is the Best Protein Powder for Acne-Prone Skin?

The best protein powder for acne-prone skin is 1) dairy-free, 2) soy-free, and 3) made with a short list of simple ingredients.

Simple ingredients are recommended because ultra-processed ingredients can alter the composition and function of your gut microbiome (North Clin Istanb, 2019).

These shifts, known as gut dysbiosis, can cause increased intestinal permeability and widespread inflammation, which is a leading driver of acne.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, and other ultra-processed additives should be a top priority for someone with acne.

⚠️ Here is a list of the most common food additives in protein shakes and powders:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you cannot find it in nature or make it at home, it is probably a food additive.

🚫 Avoid Protein Concentrates and Isolates

Acne sufferers might also want to avoid ultra-processed protein concentrates and isolates.

Most protein shakes and powders are made from one or both of these ultra-processed protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help your gut break them down.

You therefore do not digest them in the same way that you do whole foods, which could affect your gut health.

In fact, studies show that regularly eating protein concentrates and isolates might disrupt your gut microbiome (Nutrients, 2018) and cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024).

I therefore recommend only consume protein shakes and powders made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.

What Are the Benefits of Protein for Acne-Prone Skin?

Although some protein powders may cause acne, eating enough protein is essential for healthy skin because:

• Protein promotes collagen production: Protein is made up of amino acids, which are essential for collagen synthesis. Collagen is what provides structure and elasticity to your skin.
• Protein supports tissue repair: When your skin is damaged, amino acids are also needed to help repair and regenerate the damaged tissue.
• Protein helps with hydration: Adequate dietary protein intake supports the synthesis proteins in the skin, such as filaggrin, which contribute to the skin’s ability to retain moisture.
• Protein regulates oil production: Dietary protein is involved in regulating the production of sebum, the skin’s natural oil. Balanced sebum production is essential for maintaining skin hydration and preventing acne.

Basically, if you need the protein, adding an acne-safe protein powder to your diet can nourish your skin from within.

What Are the Benefits of Collagen Protein Powder for Acne-Prone Skin?

Incorporating Collagen Protein Powder into your skincare routine can be incredibly beneficial for acne-prone skin.

Research has shown that regular collagen supplements improve skin moisture, elasticity, and hydration when orally administered (Dermatol Pract Concept, 2022).

Try this acne-friendly high protein Turmeric Collagen Latte recipe to give your skin a glowy boost:

Ingredients:

• 1 serving of Vanilla Collagen Protein Powder
• 1 cup unsweetened almond milk (or milk of choice)
• 1 teaspoon ground turmeric
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon ground ginger
• pinch of black pepper (to enhance turmeric absorption)
• 1 teaspoon honey (optional)

Instructions:

In a small saucepan, heat the almond milk over medium heat until it is warm, but not boiling. Add the Collagen Protein Powder, turmeric, cinnamon, ginger, black pepper, and honey. Whisk the ingredients together until frothy. Pour the latte into a mug and enjoy its anti-inflammatory and skin-nourishing benefits.

How Do I Heal My Skin Through Diet?

Here are a few dietitian-approved tips for clearer skin:

1. Prioritize protein: Include sources of lean protein in your diet. Protein is essential for skin repair and renewal, and helps to maintain a healthy complexion. Consider using Collagen Protein Powder or eating collagen-rich foods like bone broth to support skin structure and appearance.
2. Balance your blood sugar: Prioritize balanced meals rich in complex carbohydrates, lean proteins, and healthy fats to help stabilize your blood sugar levels. Eating fiber-rich foods, such as vegetables, fruits, and whole grains, can also slow down glucose absorption, further supporting skin health. Consistent blood sugar regulation can mitigate hormonal fluctuations associated with acne, reducing sebum production and inflammation.
3. Stay hydrated: Drink plenty of water throughout the day to keep your skin hydrated and support detoxification processes, which help to flush out toxins and prevent clogged pores.
   Eat antioxidant-rich foods: Incorporate antioxidant-rich foods like berries, dark leafy greens, nuts, and seeds into your meals. Antioxidants help protect skin cells from damage and promote a healthy glow.
4. Limit added sugar and processed foods: High-sugar and processed foods can contribute to inflammation and hormone imbalances, potentially triggering acne breakouts. Focus on whole, unprocessed foods for clearer skin.
5. Include healthy fats: Include sources of omega-3 rich fats such as avocados, seafood, olive oil, nuts, and seeds in your diet. Healthy fats support skin barrier function and reduce inflammation, promoting clearer skin.
6. Practice stress management: Chronic stress can exacerbate acne, so incorporate stress-reducing activities like meditation, yoga, or deep breathing exercises into your daily routine to support skin health.

By following these tips, you can support clear and healthy skin from the inside out!
