We Never

Use harmful essential oils

Kossma does not use any harmful irritants or ingredients containing seed oils, synthetic, or filler oils in any of our products. We believe in saturated skincare that mimics the skin's natural biome, sustaining the body's natural state.

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.

Work With Nature

Kossma works with nature, using traditional distilling methods, rendering processes, and techniques known to ensure the integrity of the raw materials. Our apothecary and lab partners are dedicated to upholding these traditional extraction methods, while maintaining modern standards.

Believe that our skin can heal itself

Kossma empowers our customers to discover their skin's natural state and return their biome to it's most healthy condition.

"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!
