Summary of the issue

Why moisturise your skin?

At first glance, it is difficult to distinguish dehydrated skin from dry skin. However, each of them has specific needs and care requirements. Focus on dehydrated skin.

Why does the skin get dehydrated?

About 70% of our skin is made up of water, of which a small part, about 10%, is concentrated in its outermost layer: the stratum corneum. Together with the hydrolipidic film, it ensures the skin's barrier function. But when it lacks water, this protection is impaired and the insensible water loss increases. This means that water evaporates more easily. The skin becomes more fragile and less supple.

This is due to external factors such as wind and cold, heating, unsuitable cosmetic products, shaving, etc., but also to internal factors such as skin ageing and hormonal variations. 

The ideal skincare product for dehydrated skin must therefore combine both moisture - for hydration - and lipids - to restore the barrier function of the hydrolipidic film and limit water evaporation.

How to distinguish dry skin from dehydrated skin?


I couldn't understand why my skin was absorbing the foundation until a beautician explained that it was simply dehydrated.

What does dehydrated skin look like?

Dull, rough and tight skin, fine lines at the corner of the eyes, make-up that does not hold and causes streaks to appear on the cheeks, around the eyes or around the mouth, less elastic skin that seems to age prematurely... These are some of the signs that indicate that your skin is dehydrated. These characteristics are the same for all dehydrated skin types, whether oily, normal, combination or dry. 

Because yes, you can have oily, dehydrated skin at the same time. But if your skin is constantly oily (your skin type) it is only decreased. Luckily, it’s possible to improve the comfort of your skin as long as you choose the right products.

How to care for dehydrated skin?

Moisturise the face... and the body!

It is not only the skin on the face that is affected by dehydration. So is the body, especially in winter.

Well-moisturised legs and hands

Your legs are not spared from dehydration, and you certainly know this if you wear tights: in winter, your legs can look like "crocodile skin". Your hands can also experience from the effects of cold and repeated washing with soap or hydroalcoholic gel. Either way, moisturise as often as possible!

For super soft lips!

The skin of the lips, which does not have a hydrolipidic film and is five times thinner than that of the face, is particularly at risk of dehydration, especially in cold weather. To avoid the appearance of dry, chapped lips that are unsightly, use your moisturising lip stick or balm often.


How do you properly moisturise your body?


Hydration the shower!

A shower gel that is too aggressive and water that is a little too hard: this is the recipe for dehydrated skin on the body and face after a shower, resulting in redness and tightness. This effect can be further enhanced by the drying effect of heating.

To prevent this, we adopt gentle, soap-free cleansing products that act both to moisturise the skin and to restore the skin barrier. After the shower, moisturising products with a fluid, non-sticky and non-greasy texture, specially formulated for dehydrated skin, are applied to the body. And for the face, choose moisturisers tailored to your skin type.

A little trick to reinforce the hydration of your skin: generously spray Thermal Spring Water with soothing properties on your skin, massage with your fingertips and absorb the excess with a reusable cotton pad. Then quickly apply your skincare product to prevent the thermal water from evaporating.
