"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),

Never leaving!!

My sister-in-love introduced me to you all! She doesn’t have the vit c serum but with what I was trying to do for my skin, I wanted to give it a try. I was nervous because I have pretty sensitive skin. However, I am completely sold! Forever!! I am already seeing a difference in my skin. I thought I was crazy because it’s so soon but my skin looks and feels absolutely amazing. My dark spots are definitely so much lighter, even my 11 year old son told me my “spots” weren’t there anymore. I’m not normally the type to leave reviews but this product is truly amazing. I absolutely LOVE this vit c serum! I will forever have it! Sincerely, a basal cell carcinoma warrior! Speaking of, the scar of my forehead from removing that cancer spot is also lightening so much. It even seems to be shrinking. It was raised and reddish and now it seems to be lighter and flatter. Like I said, absolutely miracle serum!

Glowing + even skin

I love this serum. I originally purchased it because I had dark sun spots on my face. This has helped even my skin tone and leaves my face hydrated and glowing.

Top notch vitamin C serum

This vitamin C serum contains fat soluble version of vitamin C, making it more stable than typical ascorbic acid containing serums. This serum rivals some big brand products. The addition of jojoba oil makes it very moisturizing by itself. I have used in our Florida humid summer weather as a stand alone product and my face is glowing.

Love this serum

I feel like my skin glows. I use this after using my homemade face wash, then the sugar skin squaline, and the tallow balm on top. I’ve never looked better tbh.
