  • Even when the skin is sensitive, it is possible to reduce its sensitivity by eliminating the skin care products that it cannot tolerate and replacing them with specific products that are well tolerated and formulated with powerful moisturizers for the corneum layer.

Intolerances and allergies

Sensitivity, intolerance, allergy ?

Sensitivity or intolerance ? a question of degree…. Many of you have sensitive skin, but in varying degrees. It is, however, important to make a difference between sensitive and sensitized (or allergic) skin.


Sensitive skin

Fine, light, often a little dry, gets red easily.
It itches, feels tight, gets hot…
The sun is a known aggressor for the skin, specially light skin.
Cold and wind are also difficult on light skin.
Some dermo-cosmetic or therapeutic products are formulated using ill-suited ingredients:
  - Cleansers that include irritating surfactants
  - Acne treatments with a gentle peeling effect
The skin doesn’t feel any relief, on the contrary, it is traumatized by these ill-suited products.

Sometimes, your skin reacts excessively to the slightest aggression; it cannot stand anything and becomes intolerant. It itches, feels tight, gets red, scaly. In this case, it is time to choose products containing very few ingredients.

Sensitized or allergic skin

An allergy is caused by an immunological response (to an allergen).
Obvious clinical symptoms can be observed on the skin: Red patches with small eczema bumps, strong itching, swelling and oozing along with more or less intense pruritus.
If you experience allergic reactions, consult your physician without delay; Through allergy testing, he will look for and find the substance that causes your reaction.
