What does a healthy balance of the hydrolipidic film on the skin contribute to?

A healthy balance of the hydrolipidic film on the skin primarily contributes to decreased transepidermal water loss (TEWL). The hydrolipidic film is a thin layer of water and natural oils that covers the skin, serving as a protective barrier. When this film is in balance, it effectively locks moisture in while preventing dehydration.

This balance is crucial for maintaining skin hydration, as it minimizes TEWL, which is the process by which water evaporates from the skin surface. By reducing TEWL, the hydrolipidic film helps to keep the skin plump, supple, and well-moisturized, functioning at its best and appearing healthy. This is especially important for maintaining overall skin integrity, resilience, and preventing issues like dryness or irritation.

While aspects like skin elasticity, pigmentation, and cell regeneration are important for overall skin health, the most direct connection to a balanced hydrolipidic film is its role in decreasing TEWL.
