My skin supports less and less cosmetics, water, temperature changes ... How did I get there? (Marie, age 40, Saint-Brieuc)

Decoding
The case of Mary is widespread: her skin has gone from a normal state to a sensitive state . In question, a set of factors that have gradually damaged the protective barrier of the epidermis - the hydrolipidic film - and disrupted its ecosystem.
Consequence: the threshold of cutaneous tolerance decreases.

The responsible ? The limestone water of the cities, the dry air due to the heating or the air conditioning, the cold , the UV rays , cosmetic too detergent or unsuitable. Also mentioned are irritating phenomena such as air pollution or certain products that come into contact with the skin (detergents, household products, interior perfumes ...). Stress is also involved because of the special connection between the skin and the nervous system.

The right attitude
It is necessary to restore the " shield " function of the skin by providing fatty acids such as ceramides, omega 3 and 6 , which will rebuild this indispensable intercellular cement. Another reflex, play sobriety. Avoid accumulating tons of products and changing them all the time: a good day cream, a comforting mask as soon as the skin claims, a UV protection at the first rays of the sun, a rich body milk, and basta! Finally, on the house side, you can treat the problem at the source by investing in a water softener or an air humidifier.

Nerves on the skin
Every inch of skin contains about 10 hairs ... And 12 nerves! The mission of this immense nervous network? Help the body adapt to its environment.
The nerve endings transmit indeed every information (it is cold, it is too hot ...) by releasing messenger molecules, neuromediators.

The latter then generate an inflammation that causes the skin to defend itself. On a daily basis, these "messengers" are released every time the skin is attacked, which is even more common in the case of sensitive skin, their skin barrier being more permeable. It has also been proven that acute stress causes the release of neuromediators. A key, micro-inflammations cascading and ad hoc reactions: tingling, tightness ... Hence the strange feeling that sometimes the sensitivity comes from within!
