Hydrolipidic film and hydration?
The hydrolipidic film guarantees hydrated skin, and therefore nourished and healthy skin. Focus on two key concepts for our skin.
The surface of our skin is covered with a protective film called hydrolipid film, invisible to the naked eye. It allows the skin to retain water and maintain its hydration, and to give the epidermis its suppleness and softness to the touch. On the other hand, thanks to its acid pH, this film has antimicrobial properties. It thus limits the development of microorganisms and participates in the maintenance of the microbial flora on the skin surface.
When the hydrolipidic film is damaged, the signs of dry and dehydrated skin appear. Skin feels tight, itchy, reddened, flaky ... These signs are both unsightly and uncomfortable. This dryness is medically called xerosis.
The concept of hydration does not involve getting water into the skin, but preventing it from getting out of the skin. Skin hydration is linked to the barrier function and acts on two levels: on the surface by reconstituting the hydrolipidic film and in depth by ensuring better retention of skin water.
Hydrated skin gains in density and becomes more radiant. Daily hydration reduces the superficial signs of aging by restoring a more plump appearance.
