Each day the skin of face loses water and this daily water loss concerns all men and women from all countries, whatever their age or type of skin. Skin is a smart and dynamic ecosystem in permanent interaction with its environment. In normal conditions, the skin could be rehydrated naturally but some external factors such as pollution, UV rays, tobacco, alcohol, fatigue, stress and climate change increase skin dehydration by altering this natural mechanisms. The skin is no more able to generate properly its natural hydration and dehydrates. The epidermis might break down, form micro-wrinkles and tighten. Consequently, the complexion loses its natural colour and becomes dull.

This product was formulated according to the ecobiological approach of the NAOS Laboratories to take care of you. At the heart of this product:

Water and lipids are essential components of the skin, enabling it to remain hydrated. In the event of an imbalance, the skin becomes dehydrated and no longer works properly. This patented complex stimulates the synthesis of skin lipids and the expression of aquaporins. These “water channels” naturally found in the skin transport water to epidermal cells.

External stress can make the skin reactive and sensitive. This patented complex increases the skin’s tolerance threshold – regardless of skin type – in order to strengthen its resistance.

This product did not agree with me.
I am using other products from the Bioderm range, which have all beenn fantastic so I thought I would try the Serum , within a few hours I could feel the irritation on my skin & my Eczema flaring up. I was very disappointed as it was not a cheap product

Worth every penny
This serum is fantastic, I tried lots of other products but nothing else worked until I found this. I’m suffering with very dry menopausal skin and other creams couldnt stop my skin peeling but this serum works beautifully. Buy it, you’ll not be disappointed. We only thing is I’d appreciate a travel size version as well as refilable bottles as I think that is something that responsible companies need to begin.
