Compromise our values

Kossma is revolutionizing skincare. We are boldly stepping out of Unsaturated synthetic skincare that is sweeping the beauty industry, but Saturated skincare that mimics our skin's NATURAL biome, restoring our natural glow, with healthy animal fats and whole plant extracts.

Use products from factory farms

Kossma does not engage in harmful mono crop agriculture. We are dedicated to regenerative practices that restore nature, as it was intended. Regenerative skincare is Sustainable skincare, using farming techniques that actually create carbon negatives, rather than fictitious net zero claims, popular today.

"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 Vitamin C Serum


Our pure and potent Vitamin C Serum contains a highly effective antioxidant complex, THD Ascorbate (vitamin C) and mixed tocopherols (full spectrum vitamin E), along with skin-nourishing jojoba oil. These ingredients work together to boost collagen production, reduce the appearance of yellow-brown pigment spots, and brighten the skin while shielding it from UV, environmental, and PUFA damage (Lipofuscin).

This serum features a highly stable and gentle C Ester in jojoba oil, which has the ability to deeply penetrate the dermis and increase skin cell viability by up to 30% when compared to L-Ascorbic Acid. Its oil-soluble formula is gentle on the skin, making it an ideal choice for those seeking to enhance the health and appearance of their complexion.

We consider this formulation as essential for providing nutrients to the skin, enhancing its texture, balancing pigmentation, and boosting collagen production to result in a firmer and plumper complexion.

    Excellent product!

    I love this product. I have been using this serum for a couple of months and my skin feels softer and my complexion looks healthier. I use it day and night.

    Love it!

    I've been using the Purely Potent Vitamin C serum for several months now and I am loving it! I use morning and at night and layer underneath the New Moon Serum and Marshmallow Hydrosol. Since using Kossma products, my skin feels incredible! It's hydrating while also being light enough to wear underneath makeup if needed. It is my favorite!

    So far so good, I see already my face is lighter, like I had a little sun spot after the summer and it is disappearing already. I think it will help me to have a better and looking even skin, and since it is still a little hot here, the only thing I feel is that it is a little heavy for my skin, since I have oily/mixed type and with the heat gets even more. But I think it will be better for using during the night and also when the colder months arrive ;)

    The best Vitamin C I have tried!!

    This is the best lightweight Vit C I’ve ever tried. I love that it sinks into the skin almost instantly and works for my sensitive skin. Definitely helps any sun spots, I’ve been in the sun the whole summer and used kossma thallow products and this serum I think does the trick for my skin. Thank you Kossma. Already telling my friends what I use🤍

    Happy hydrated skin!

    I always deal with super dry skin, and this serum seems to have brought my skin back to life! I’m really happy with it, and look forward to using it morning and night before the tallow balm. I definitely recommend this to anyone who needs a little skin boost!
