What are the Cellular Mechanisms Behind Skin Hydration?
Skin hydration involves various cellular mechanisms:
Keratinocytes: These cells produce Natural Moisturizing Factors (NMFs) and contribute to the formation of the lipid barrier. Fibroblasts: Located in the dermis, they produce collagen and elastin, which help in retaining moisture. Sebaceous Glands: These glands secrete sebum, which helps to maintain the lipid barrier.
