Many patients have skin problems related to the production of an excessive amount of sebum. Various factors can cause this, such as ultraviolet rays, genetic predisposition, stress, hormonal imbalance, etc.It is particularly important to determine the type of skin in order to take the best possible care of it. Every skin type is different and undergoes changes over time.Alpha-hydroxy acids (AHAs) are of great interest today. They are a group of plant and animal products widely used in cosmetics.This article aims to summarize literature data on the effects of AHAs in photoaging skin.To achieve this goal, a literature review method was used. The reviewed literature sources were selected from PubMed, Scopus, and Google Scholar databases.AHAs act delicately and gently, removing the upper layers of the skin in a non-invasive way, where dead skin cells and impurities accumulate. Then they penetrate downward and build a natural protective barrier on the lower layers of the skin, which strengthens its resistance to various external influences. As a result, the skin becomes clean and smooth, with a softened relief and increased absorption.AHAs are used for various skin problems, such as wrinkles, acne, dark spots, problem skin, and imperfections. They are used in combination with other active ingredients in cosmetics, in the composition of daily anti-aging products such as serums, toners, and creams, and in various preparations for chemical peeling
