“Chemistry Lessons” is a series of entertaining and educational videos from Re[Sens], the first Ukrainian high-biotech sustainable professional skincare brand. This project was created to explain the complex in simple terms — and to make the world of cosmetics more accessible, honest, and conscious.

The main face of the project is Yuliia Gaharyna, co-founder of Re[Sens], cosmetic chemist, and skincare formula developer. With humor, sincerity, and expertise, she reveals how cosmetics work — from the inside out.
