Part 2: The Biological Reality of Skin Aging and Barrier Function

Understanding skin anatomy helps separate basic occlusive hydration from sensationalized DIY skincare claims.

Wrinkles, skin laxity, and age spots result from a gradual loss of collagen, elastin, and subcutaneous fat caused by intrinsic aging and cumulative ultraviolet (UV) damage.
