Common questions

Protein and acne

Updated: October 25, 2026

In some people whey protein can worsen acne — dairy proteins raise insulin and IGF-1. Not everyone reacts.

If it happens to you:

  • Switch to isolate or try a plant protein.
  • Use smaller servings and get more protein from food.
  • Cut sugar and gainers.

Severe acne — see a dermatologist.
