? Sensitive skin: why

Doctors and researchers are trying to understand how, or rather the ways that the skin works, and why, more and more often, it rebelled against the environment. Indeed, one in two women complained of having sensitive skin, and it is a regular pattern of consultation to the dermatologist

What we knew

The skin is covered by a huge network of nerves. This, it was discovered a long time ago. She has even more nerves per square centimetre (twelve) and hair (ten)

What is new

On the other hand, it is less than ten years that we know that the skin also secretes substances that only the brain produces: the neurotransmitters (or neurotransmitter), which have a very important role in inflammatory processes

These proteins made by neurons, in granules or vesicles, are released outside in case of need. They attach themselves to the surface other specific cells: receptors. It is convenient to fill the brain permanently on the skin feels, and give him control of all of its duties. When Dr. Laurent Misery talks about in his book "The neuronal skin", it specifies that brain and skin are "brothers Embryological and nostalgic" because during embryonic life, their cells are confused and, even when they differ, they retain links, have a common language. This is what is called the neuro-immuno-skin system

Skin: a pain that does not

"I have bad skin, I can't stand anything!" When it does not, it does not believe you. And this complaint is taken for the sentimentality

It was often the case.. until this pain evaluation test developed by scientists from l oreal neurophysiologists specialists of brain functional imaging by magnetic resonance of the cnrs and ilnserm. They observed the brain activity of two groups of people (skin sensitive / non-sensitive skin), in an assay of skin reactivity using an irritating active, lactic acid, on the face.

The results reveal that in (right or left) areas of the face that has been applied the substance, brain activity is much greater.

Skin: a sometimes genetic susceptibility

Can be more or less genetically prone to this excessive sensitivity of the skin: this is what dermatologists call an endogenous origin. Light skin being the most affected

Then, one can become reactive due to invasive and repeated gestures. Too 'perfect' hygiene, cosmetic removers, frequent recourse to peels or lasers, or abuse of Sun accelerate the process: these are environmental causes.

But he must not forget the psychological origins, the psyche is closely related to the bodily sensations, studies American performed on children suffering from eczema reveal that massaged daily, they need less of to Corticoid ointments. An exacerbated skin sensitivity might therefore be related to stress, or even psychological suffering

! Sensitive skin: no water

Women to the ultra-sensitive skin, the skin barrier, this small invisible protective film that is on its surface, is deficient. It is porous and lays me bare. Result: the water it contains evaporates, it dries out, and everything you apply above does it warm up, the tingle or burn

Forget water

In any case, tap, unless you live in the heart of the Auvergne, where she is incredible softness. Otherwise, use a thermal waters. With regard to the makeup of the evening - which requires products effective but soothing, to clear mascara or the Foundation - a cream or a make-up Remover oil suited

Absolutely, avoid conventional soaps, which eliminate the skin barrier for several hours, no-rinse cleansers & wipes. Because less remains active residue on the surface, better your skin is
