Myth: dry skin

My skin is dry because I do not drink enough water.

Not really, no...

Unfortunately, it is not so simple. Although drinking water is essential to our health, no study suggests that consuming more water would have a direct impact on skin hydration. In fact, the skin dries out when its barrier is not able to retain enough water in the skin. stratum corneum (une couche superficielle de la peau) et qu'elle s'évapore dans l'atmosphère. Plus précisément, si la peau contient moins de 10% d'eau, elle aura tendance à devenir sèche. Plusieurs facteurs peuvent exacerber ce problème, nommons entre autres, l’exposition non protégée au soleil, la saison, les variations de température, l’état de santé, l’environnement, le type de chauffage domestique et l’utilisation de mauvais produits cosmétiques.

Whatever the source of the problem, and there may be more than one, it is by restoring the moisture barrier of the skin that it can be allowed to remain healthy. The best tools to do this are to use proper cosmetics and to wear sunscreen, minimum SPF of 30, every day!
