"The best vitamin c serum I’ve ever used! Helps improve dark spots like nothing else and has improved my overall complexion!" -A S

Purely Potent | Non-Oxidizing Vitamin C Serum

$52.00

Description

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).

Our 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.

(Non-Oxidizing Vitamin C),

Great product

Love this vit C serum for its deeply moisturizing and brightening effects. Every Kossma product has been superior to anything else I’ve tried in the past and I cannot imagine using any other brand in the future
