Stabilized vitamin C is a derivative or formulation of ascorbic acid (e.g., sodium ascorbyl phosphate, magnesium ascorbyl phosphate, ascorbyl glucoside, tetrahexyldecyl ascorbate) designed to resist oxidation. It provides antioxidant protection, supports collagen synthesis, and helps reduce hyperpigmentation and uneven skin tone.
