Bioderma Hydrabio Moisturising Skin Toner is a hydrating, moisture-generating toning lotion that provides an immediate and lasting sensation of freshness while toning and moisturizing the skin. Formulated with the patented Aquagenium™ complex, it helps the skin activate its natural moisturizing abilities by stimulating the production of aquaporins, water channels that retain essential moisture for a balanced complexion. The skin toner offers eight hours of hydration and works to restore the skin's natural moisture balance by supporting the synthesis of lipids and promoting efficient water transport to the epidermis. With a lightweight, non-comedogenic texture, it provides excellent cutaneous and ocular tolerance without the need for rinsing.
