Abstract
BACKGROUND: One of the ways to treat acne is by using chemical peels. Salicylic, glycolic and pyruvic acids due to their keratolytic and antibacterial properties are often recommended for acne patients. AIMS: The aim of the study was to compare the effect of a preparation containing glycolic and salicylic acids with pyruvic acid. PATIENTS/ METHODS: 14 women diagnosed with acne took part in the study. The facial treatment area was divided into two parts: right (a preparation containing 50% pyruvic acid) and left side ( a preparation containing glycolic and salicylic acids). A series of four treatments was performed at 2-week intervals. Skin parameters, namely hydration, sebum secretion and skin colour were measured. RESULTS: As a result of using 50% pyruvic acid, the hydration of the right side of the face increased statistically and there was a decrease in the amount of melanin in the epidermis. On the left side of the face, there was an increase in skin hydration after using a mixture of glycolic and salicylic acids. The increase in skin hydration on the left side of the chin and nose was not statistically significant. The use of the mixture of glycolic and salicylic acids affected the skin colour on the left side of the face, on the forehead, cheek and nose. CONCLUSION: Chemical peels affect a wide range of pathological factors of acne. A mixture of acids yields fewer side effects than a single acid used in high concentration, but the therapeutic effects are comparable.
