study of substance penetration through skin in lab settings
In Vitro Skin Absorption refers to the process of studying how substances penetrate the skin using laboratory techniques outside of a living organism. This method involves applying a substance to a skin sample, often from human or animal sources, and measuring how much of the substance passes through the skin layers. It is commonly used in research and product development to assess the safety and efficacy of topical medications, cosmetics, and other skin-applied products.
