    Sacred Skin+

    Salicylic acid, derived from willow bark, is a potent acne-clearing agent. It works by deeply penetrating the pores to dissolve skin debris that clogs pores, acting as an exfoliant to promote the shedding of dead skin cells. This action is complemented by the combined effects of pinion resin, echinacea, calendula, and poplar buds. Pinion resin possesses anti-inflammatory and antimicrobial properties, reducing acne inflammation and preventing bacterial growth. Echinacea enhances skin regeneration and reduces redness, while calendula soothes the skin and reduces irritation. Lastly, poplar buds, rich in salicin, further aid in exfoliation and maintain clear pores. Together, these ingredients create a synergistic formula that not only clears clogged pores but also keeps them clear, preventing future acne breakouts.

    What's inside

    Black Willow Bark clears pores of dead skin and bacteria. It provides anti-inflammatory, soothing, and antiseptic benefits.

    Myrrh Resin stands out due to its pharmaceutical-grade medicinal properties. Its antifungal and antibacterial qualities are especially effective in treating both acne and fungal acne.

    Calendula Flowers have anti-inflammatory,
    antioxidant, and antimicrobial properties,
    making them useful in treating skin conditions,
    such as eczema, psoriasis, and acne.

    Nature is simple.

    So is Kossma. That's why we are proud to be an animal forward wellness company. Kossma products are grounded and work with nature to promote essential wellness for the mind and body.

    I am 16 years into the chronic acne game. Fully trusting Stephanie, I ordered this serum. I LOVE the smell and texture. Honestly, I have used other products that have worked faster. BUT they always stop working or eventually dry out the skin or upset the skin barrier. This is the only product I have tried that consistently improved my skin in all aspects for a long period of time.


    This is amazing for locking in the moisture after using a hydrosol! I’m very happy with it.

    Great product

    I’ve had oily/dry skin in the past. Most moisturizers would break me out. This product from kossma works great. It makes my skin feel hydrated, reduces old marks, and fights against new ones.

    Great at shrinking blemishes

    I occasionally get cystic acne and dermititis due to gut issues that I'm working on. This serum has definitely aided in reducing the size of painful cystic acne and redness of the dermatitis. Not quite moisturizing enough on its own for my drier skin so I pair it with the Shea butter. My skin is soft and starting to look healthy again while the breakouts heal. The infused herbs and resins make a difference and are so much better than harsh "acne treatments" which dried out my skin so much.

    Teens friendly!

    My teenager doesn’t want to use anything “natural” but this one won her skin so she’s on her second bottle and she even tried the mature skin kit and now is skipping the harsh chemical filled skin products! Thanks!!
