Sensitive skin or facial irritable syndrome affects many persons, and almost one in five women. 

Sensitive skins are particularly responsive to stressful situations (extreme temperatures, wind, sun, etc.) and also to the use of certain cosmetic products. They have redness on the face, tightness or even frequent tingling.

In addition, the more the skin is dehydrated, the more sensitive it is. Also, the sensitivity of the skin will change with the seasons and the lifestyle of a person.
