Cosmetic Science

~60 min · 15 stations

Cosmetic Science is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify core chemical components within common cosmetic formulations; explain the biological structure of the human epidermis; categorize substances based on their solubility in oil or water.
