Common Name(s): Ferrous lactate,ferrous lactate,cosmetic functional ingredient,established active
CAS Number: N/a
DESCRIPTION
What It Does: Provides trace mineral or guanidinium ion delivery for skin cell enzyme cofactor activity, antioxidant function, or cellular signalling.
Why It's Used: Mineral salts provide essential trace elements in bioavailable ionic forms — the counterion determining solubility, bioavailability, and skin compatibility.
How It Works: Metal ions (fe²⁺/³⁺, co²⁺, ga³⁺) serve as enzyme cofactors, radical scavengers, or structural components of metalloproteins in skin cells.
