reactive skin

The skin no longer fulfil its barrier function, which makes it more sensitive to external aggressors. Environmental molecules called allergens such as pollen, dust, etc. can, therefore, penetrate the skin more easily and come into contact with the skin's immune cells. This triggers an inflammatory response that causes the itchiness and dry skin patches. This lack of hydrolipidic film is also accompanied by significant skin dryness.
Your esthetician recommends using toiletries that are suitable for ultra dry skin. These are formulated without fragrance, with mild surfactants and have a physiological pH so that they do not irritate the skin but rather hydrate it durably and soothe itching.
Daily application of an emollient helps to space out flare-ups and reduce the use of corticosteroids
