Kosi Multi-Acid Mask

A multi-acid mask and skin resurfacer with a reparative antioxidant-boosted formula.

All good skincare routines could use a coach or point-person to keep your progress in check. Consider this mask your periodic skincare project manager or concierge, making quick work of issues like dullness, splotchiness, and any visible signs that you’re not drinking 64 ounces of water daily. Kosi goes beyond superficial layers, reaching down to the cellular level to help prevent future skin damage as well — this is not just another exfoliating resurfacer. With a multi-functional acid blend, reparative antioxidants, and the power of algae and seaweed, this formula is meant to recharge skin back to its most vibrant, refreshed, and energized self.

Holifrog products are nutrient-rich and infused with natural active ingredients for your best skin yet.

On a cleansed face, apply an even layer. After 10 to 20 minutes, rinse thoroughly with warm water.

"And now, the dawn of the Kosi Multi-Acid Mask is upon us. It exfoliates from seemingly every angle — AHAs, BHAs, and even PHAs (polyhydroxy acids) — to help skin look more alive, all the while moisturizing and protecting it with peach kernel oil, jojoba oil, and glycerin so you see more even skin — not the red splotches that sometimes come with excess exfoliation."
