The body's first barrier against the environment, the skin, with its complex structure in 3 layers (epidermis, dermis and hypodermis), provides complete protection. The protective functions of the epidermis are largely ensured by sebum. Major constituent of the hydrolipidic film, it protects the skin against microbial attacks, participates in the lubrication of the skin and contributes to the elastic properties of the skin.
In cold weather, the skin plays an essential protective role by preventing the body from cooling down. This fight against heat loss results in cutaneous vasoconstriction which in particular generates a slowing down of sebum secretion by the sebaceous glands.
At the level of the epidermis, the cold slows down the enzymatic reactions responsible for the degradation of “dead” cells. This leads to an accumulation of dry cells. Simultaneously, the cold and the wind attack the hydrolipidic film. Stripped of its protection, the skin dehydrates more quickly, dries out, becomes rougher, tight and tingles.
To avoid skin dryness, several simple measures must be adopted and repeated throughout the winter season:
Prefer surgras soaps and moisturizing soaps.
Apply a soothing and moisturizing* cream to the face and body to preserve or restore the hydrolipidic film, while calming and softening skin irritated by the cold.
Opt for a supplement helping to provide your body with gamma-linoleic acid (polyunsaturated fatty acid) which helps to preserve beautiful skin and maintain its elasticity.
