Purely Potent Vitamin C Serum

$86.00 CAD

Kossma's Vitamin C Serum is a blend of pure, potent antioxidants, featuring THD Ascorbate (Vitamin C) and full-spectrum Vitamin E, combined with the nourishing properties of jojoba oil. This formula is crafted to boost collagen production, diminish yellow-brown pigment spots, and brighten the skin while providing protection against UV, environmental, and PUFA damage (Lipofuscin).

This serum is uniquely formulated with a stable, non-oxidizing, and non-irritating form of Vitamin C, guaranteeing potency and stability. This sets it apart from the commonly used ascorbic acid, which is prone to oxidation and can irritate and sensitize the skin.

The oil-soluble formulation enables deep dermal penetration, boosting skin cell viability by up to 30% compared to L-Ascorbic Acid. This feature makes it an ideal choice for anyone seeking to enhance their skin's health and appearance with a gentle, natural, yet highly effective solution.

Best used on dull skin, to improve laxity, hyperpigmentation, and melasma.
