Abstract: BACKGROUND Based on personal observations of dermatologists, nutritionists and patients, a new problem emerges in the gyms: development and exacerbation of acne in users of whey protein, which is a protein derived from cow's milk. Whey Protein extract contains growth factors that may be related to acne. Its purity and composition are not fully known and there is no scientific research on its potential to cause acne.

“…Whey proteins are predominantly responsible for the insulinotropic effects of milk, whereas casein stimulates IGF-1 to a greater extent than whey [ 56 ]. Hyperinsulinemia, such as that caused by the insulinotropic effects of milk whey proteins, also increases IGF-1 levels, which could provide a potential explanation for why those taking whey supplements, as has become common practice in fitness centers and weights-based athletic pursuits, present with an onset or aggravation of acne [ 57 , 58 ].…”

Furthermore, the progressive use of protein-calorie supplementation was discouraged in a study in Brazil because of its association with the onset of acne within a two-month period (8).…”
