Skin Barrier Theory

Skin Barrier Theory refers to the concept that the outer layer of our skin acts as a protective barrier against environmental challenges, like bacteria, allergens, and moisture loss. This barrier is primarily made up of lipids (fats) and proteins that help maintain hydration and shield against external irritants. When this barrier is compromised, it can lead to skin issues such as dryness, irritation, and increased susceptibility to infections. Proper skincare, including moisturizing and protecting the skin, supports its barrier function, promoting overall skin health and resilience.
