Bee pollen is a natural material rich in biologically active substances such as enzymes, polyphenols, carbohydrates, proteins, fats, fatty acids and amino acids. Many of them have a recognized role in cosmetics. Aim. The aim of the study was to assess the effect of cream with aqueous bee pollen extract on the hydration and pH level of the young women´s skin of the hands. Material and methods. 14 cosmetology students who met inclusion criteria (no allergy to bee products, no use of elimination diets, no dermatological and endocrine diseases and a negative patch test result for the tested cream) were randomly assigned to the test group (pollen cream), or control (cream base). Before and one day after the 5-day treatment, a moisturizing and pH test of the skin were made. The questionnaire survey allowed for subjective assessment of skin condition. Results. Increase in hydration was indicated in both groups (p=0.0471 and p=0.1498, respectively, for the test and control groups). The pH level in both groups decreased: in the study group by 0.12 units (p=0.1128), and in the control group by 0.42 units (p=0.1770). Volunteers from the study group reported a subjectively higher level of skin hydration. Conclusions. A 5-day treatment with an aqueous bee pollen extract cream gives a subjectively assessed increase in skin hydration. Observations with a longer exposure period seem advisable.
