Sérum TEWL - Biologique Recherche

Sérum TEWL is a nourishing face serum for dry skin, designed to deeply moisturize and reinforce the skin's protective barrier. Ideal for extremely dry, sensitive, or lipid-depleted skin, this ultra-rich serum restores comfort, suppleness, and hydration.

Ultimate Protection Against Trans-Epidermal Water Loss

This serum is formulated to combat Trans-Epidermal Water Loss (TEWL), which leads to dryness, irritation, and premature aging. With a high concentration of essential fatty acids, botanical oils, and antioxidants, Sérum TEWL forms a protective film that seals in moisture and defends the skin against environmental aggressors.

Especially recommended for harsh climates, post-procedure recovery, or winter dryness, it leaves the skin feeling smooth, nourished, and resilient. Can be used alone or over lighter serums and creams for added occlusive protection.

How to Use

Apply a few drops of Sérum TEWL in the evening to clean skin, after lighter serums and before or instead of a cream. Massage gently until absorbed. Use 2-3 times a week or daily in extreme dryness.
