Biologique Recherche Serum T.E.W.L. 30ml + 8ml

Serum T.E.W.L. is a protective serum. I find it is really essential for a lot of skins. Trans Epidermal Water Loss is when your skin is unable to hold water. Undernourished skins lack lipids and feel really dehydrated. This treatment serum is used to restore lipids and form a lipidic shield allowing the skin to repair and hold water. Active ingredients like Phytosterols, Raspberry Seed Oil Extract, Jojoba Oil and Cranberry Oil all work to restore and protect against external factors.

Natalie’s Use Instructions:

Serum T.E.W.L. can be used as the last step in your routine. Use 2 or 3 drops and warm in the palms before pressing into the skin as a protective layer. If you are exposed to very cold or dry climates this acts as a barrier for the skin. I like to use it on my skin in wintertime on long walks! Not for use on oily skins. Can be used as a more intensive treatment for undernourished skins. Please have a consultation for customised advice.
