Biotherm Biosource 24h Hydrating & Tonifying Toner ( Normal And Mixed Skin ) 200ml

The Biotherm Biosource 24h Hydrating & Tonifying Toner restores moisture balance and clears cleanser residue in normal to combination skin using a fast-absorbing, paraben-free formula that primes every layer beneath. Each 200 ml bottle centers its activity on Life Plankton™, delivering a precise blend of proteins, amino acids, vitamins, and trace nutrients that actively rehydrate surfaces without leaving a greasy film.

This water-light liquid tackles the dual challenge of mixed skin textures by lifting lingering impurities, balancing surface pH, and supporting cell renewal while you wait for heavier products to work. Apply across the face or press directly into the skin with clean fingertips after patting dry post-cleansing. The formulation settles completely within seconds, creating a uniform, slightly damp base that significantly improves active ingredient penetration and prevents the tight, stripped sensation common with astringent toners.

Designed around sustained hydration rather than temporary shine control, this toner functions best as a daily bridge step between washing and treatment serums. It layers cleanly under most moisturizers and sunscreen formulas without pilling or migration, making it a practical replacement for traditional astringents when your priority is long-term barrier support and stable complexion maintenance.
