Young skin is sensitive and fragile compared to that of an adult. The difference in skin structure contributes to the fragility of young skin as opposed to the skin of an adult. Made up of different kinds of cells, the epidermis is the out most layer of the skin. The epidermis is 20-30% thinner in tweens/teens therefore much less resilient than adult skin. A tween/teens skin is thinner and has a higher body surface area, so it more easily absorbs toxins; therefore, gentle, simple and safe products specifically designed for tween/teen skin should be used.
