Does protein powder cause acne?

Written by Bodycraft | Jan 13, 2026 8:59:16 AM

There is a correlation between protein powder and skin problems; however, that link is very dependent on the kind of protein you are using.

The Whey Factor: Why Dairy Might Be the Culprit

Most gym-goers reach for Whey protein because it’s effective for muscle growth. However, Whey is derived from cow’s milk, which contains a hormone called IGF-1 (Insulin-like Growth Factor 1).

When you consume Whey, your body’s IGF-1 levels spike. This triggers two major acne-causing events:

  • Overactive Oil Glands: Your skin starts producing excess sebum.
  • Rapid Cell Growth: Skin cells multiply faster, which can lead to clogged pores.

Comparing Protein Sources and Acne Risk

Not all powders are created equal. If you suspect your protein powder causes acne, look at how different sources stack up:

Protein Type

Acne Risk Level

Why?

Whey Concentrate

High

Contains high lactose and growth hormones.

Whey Isolate

Medium

Lower lactose, but still triggers insulin spikes.

Pea / Soy / Rice

Low

Plant-based; no dairy hormones or IGF-1 spikes.

Egg White

Low

Dairy-free and low-glycemic.

 

It Might Be the Sweeteners, Not Just the Protein

Most of the protein powders on the market are loaded with artificial sweeteners (for example sucralose) and fillers (for example maltodextrin). Maltodextrin has a higher glycemic index than table sugar and fast insulinemia can result from it, which in turn can lead to fast skin inflammation.How to Keep Your Gains and Clear Your Skin

How to Keep Your Gains and Clear Your Skin If you are not willing to give up your protein shakes, then wear these expert tips:

  1. Be a Plant, Based: Temporarily change to a top, quality pea or hemp protein for 30 days and verify if your skin gets better. 
  2. Look for "No Added Sugar": Do not use powders that contain high, glycemic thickeners. 
  3. Cleanliness after Workout: If you are sweating while exercising, wash your face and body right away. On occasion, "protein acne" is the sweat that is trapped in your pores.

Conclusion

Is protein powder the cause of acne? For a large number of people, the answer is yes, mainly a dairy, based Whey. You can still gain muscle without losing your beautiful skin by switching to a pure, plant based product and being careful about the hidden sugars.
