Study on the ability of Betulogel, a cosmetic product containing high specific surface birch bark extract, to reduce skin pigmentation

A group of researchers will evaluate the effectiveness of the newly developed cosmetic product by applying a questionnaire to the research participants involved in the doctor-dermatologist's practice site.
The developed cosmetic product contains an extract of plant origin (birch bark), the main component of which is Betulin.
Participants of the study will be regularly evaluated for the skin condition, degree of pigmentation, volume of the hyperpigmented skin region, as well as digital dermatoscopy will be carried out during each visit.
