Sérum T.E.W.L. is formulated with an ultra-high concentration of precious lipid-replenishing, repairing and protective oils. The combined action of its active ingredients restores a strong cutaneous barrier and strengthens the hydrolipidic film so skin is better able to shield itself from external aggressions. The serum’s formula envelops skin like an epidermal shield, providing intense nourishment and supreme comfort. Once repaired and protected, the epidermis maintains an optimal level of hydration.

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, also accompanied by significant sensations of tightness and signs of minor lines associated with superficial dehydration of the epidermis.

Recommended for skin that is lacking in lipids and nutrients.

*Wonderful for dry winter skin

Can be mixed into any BR cream to boost lipids and hydration for the winter months. I would not recommend this for oily or acneic skin. 


Apply 2-4 drops to the entire face, neck and décolleté and massage in with fingertips until completely absorbed, can also be mixed with your cream.
