Hyaluronic acid is one of the most important organic chemicals in the human body. In the human body, it is mostly found in the skin in the form of an intercellular space filler. Hyaluronic acid has the ability to bind a large amount of water in the skin, what provides the proper hydration. Unfortunately, human skin ages over time, which leads to a decrease in the amount of hyaluronic acid. This is one of the main reasons for the decrease in skin firmness and hydration, as well as the formation of wrinkles. Hyaluronic acid is used as an implant to enlarge the lips or fill wrinkles. In addition, in mesotherapy treatments to moisturize and revitalize the skin. Moreover, it is a substance that is the basic ingredient of moisturizing creams. Aim. The aim of the study was to assess the effect of hyaluronic acid on the level of skin hydration. Material and method. The research was carried out on 20 women, aged 25-50. Women were divided into two groups: 10 women aged 25-40 and 10 women aged 41-50. In each group, 30% hyaluronic acid (Water Drench Hyaluronic Moisturizer by Peter Thomas Roth) was applied externally to the skin. The degree of skin hydration was tested with the SK-30 (Digital Moisture Monitor For Skin) hygrometer tn three parts of the face: forehead, cheek and chin. Results. The initial measurement of skin hydration in women aged 25-40 on the forehead was 33.1%, on the cheek 31.6%, on the chin 35.4%. However, in the group of participants aged 41-50, the hydration of the skin on the forehead was 30.1%, on the cheek 28.9%, and on the chin 32.2%. After 14 days of treatment with the product with hyaluronic acid in women aged 25-40, the average measurement of skin hydration on the forehead was 41.3%, on the cheek 38.8%, on the chin 43.2%. In women aged 41-50, the average measurement of skin hydration on the forehead was 36.5%, on the cheek 35.8%, and on the chin 38.6%. Conclusions.
