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. Recommended for Skin Instants© that are lacking in lipids and nutrients.
