Today, moisturizing treatments are not only about making our skin look pretty. They also slow down its aging. Our skin captures more than 10% of the water present in our body. This precious drink is diffused via the blood vessels, goes up towards the epidermis by impregnating each cell, then evaporates once on the surface. Before, cosmetics formed a shield to block this evaporation called insensitive water loss through humectants and lipids. It was fine, but not enough.

How to strengthen skin moisture?

Enlightened by recent advances in understanding the skin mechanisms, the labs have focused on NMF, alias natural factors of hydration . Produced by keratinocytes, these amino acids, minerals or sugars, act like water magnets and help the skin to better manage its reserves. Another key element is the aquaporins , whose discovery was rewarded by the Nobel Prize for Chemistry in 2003. These proteins form a micro-irrigation network that transports water from one cell to another and improves its distribution. All these elements, present in the body, are now integrated into our creams.

High-tech treatments for well hydrated skin

The stakes are enormous, because this immense network of sensors and channels not only guarantees a comfortable, supple, rebounded "skin mattress". Without it, the cellular metabolism turns slow ... and the skin ages faster! The new high-tech moisturizers play a crucial role: one moves from a superficial hydration, dressing, to a deep hydration , which is born in the heart of the cells. Is this not the best way to preserve its youth capital?
