Sérum T.E.W.L., a genuine lipidic shield, is more specifically appropriate for extreme conditions of cold and low air humidity. It is ideal for very lipid-deficient Skin Instants, also accompanied by significant sensations of tightness and signs of minor lines associated with superficial dehydration of the epidermis.

Apply a few drops of Sérum T.E.W.L., instead of the regularly used Finishing Serum, all over the face, neck or décolleté and massage with fingertips until fully absorbed by the skin.
