Food ingredient guide
Whey protein and acne
Whey is a milk-derived protein common in sports nutrition and packaged foods. Some acne-prone people choose to track it, but current evidence does not show that whey causes acne in everyone.
Names to look for
Labels may list whey protein concentrate, whey protein isolate, hydrolysed whey, milk protein, or whey powder. Products marketed as high-protein can contain more than one dairy-derived ingredient.
How to use the information
If you suspect a pattern, avoid changing many variables at once. A scan history can help you remember exposures, but persistent or severe acne deserves professional care.
