hydrolipidického

Hydrolipidického is a term derived from Greek and Latin roots, referring to the balance between water (hydro) and lipids (fat) within a specific biological context. In dermatology, it most commonly describes the hydrolipid film, also known as the acid mantle, which is a protective layer on the surface of the skin. This film is composed of sebum, a lipid-rich secretion from sebaceous glands, and sweat, which provides the aqueous component.

The hydrolipid film plays a crucial role in maintaining skin health. Its acidic pH, typically between 4.5 and 5.5, inhibits the growth of pathogenic microorganisms and supports the skin's natural barrier function. This barrier prevents excessive transepidermal water loss, keeping the skin hydrated and preventing dehydration. It also protects the skin from environmental aggressors and irritants.

Disruptions to the hydrolipid balance can lead to various skin concerns. For instance, a weakened hydrolipid film can result in dry, sensitive, or irritated skin, making it more susceptible to conditions like eczema or dermatitis. Conversely, an overproduction of lipids can contribute to oily skin and acne. Maintaining the integrity of the hydrolipid film is therefore essential for healthy, resilient skin. Skincare products often aim to support or restore this delicate balance.
