In: Recipes and advices On: Hit: 139

Is the dilemma often behind the angle, when we must purchase a cream for the face or body: moisturizing or nourishing cream? Which are the differences?

First of all it needs to understand the specific action of the product: to hydrate means "to get to absorb the water" and not (as many mistakenly think) "to introduce water." The moisturizing creams in fact can help to recall the water that is already present in the deep layers of the skin toward the most superficial layer, thanks to wetting substances.

The nourishing creams reconstitute that sort of hydrolipid film (composed by water and fats) that acts as adhesive for the cells, forming a barrier that protects the skin from the aggression of the external agents. This adhesive is mainly composed from hydrolipid molecules called ceramìdes and nourishing creams’ action is to nourish the adhesive through substances defined soothing. The ceramìdes are chemically countersigned by the amid bond, that it is proper for to remain in a watery solution and that, as soon as he climbs toward the superficial layer of the skin, enables the alternation of layers of water and fat substances in which we find again that damp allows that it usually evaporates.

Completely moisturizing or nourishing creams don't exist, but they are mainly moisturizing or nourishing, because the skin needs of both of them. For the fat skins they are more proper the first ones, since they already abound in nourishing substances; for the dry skins, instead, the seconds will be ideal.

The oily substances as oil (in primis the olive oil) and fat are soothing, hygroscopic and water soluble substances are (es. the glycerine) are wetting. Attention to the INCI to understand the degree of effectiveness of the action that the cosmetic product publicizes.
