Kosi Multi-Acid Mask

This 11% blend of AHAs (glycolic, lactic, phytic, citric) and BHAs (salicylic acid) gently scoops away dead skin cells and helps clear pores of excess sebum.

FOR: Dull, rough, or congested skin that could use an overnight resurface.

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 (who has the time?).

• Brightens skin overall, diminishing hyperpigmentation and dullness, while restoring vibrancy to skin tone.
• Penetrates below skin’s surface to repair damage on a cellular level, preventing the appearance of future damage and premature aging.
• The multi-functional ingredient profile exfoliates, hydrates, repairs, and protects against inflammation (kind of like AAA for your skincare journey).

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.

KEY INGREDIENTS:

• 10% AHA Blend: Lactic, Mandelic, Malic Acids are chemical exfoliators of various molecule sizes. They gently break down debris and dead skin cells loitering on the skin's surface.
• 8% PHA (Gluconolactone): An overachieving acid exfoliator that not only does what AHAs can do, but it’s gentler because it simultaneously hydrates skin with humectant properties.
• 2% BHA (Salicylic Acid): A larger-molecule exfoliator, this acid is oil-soluble, so it can actually penetrate pores to more deeply clear them of debris and gunk, including shrinking blackheads and whiteheads.
• Diglucosyl Gallic Acid: This molecule is activated by your skin’s microbiome, partially transforming it into Tri Hydroxy Benzoic Acid, a natural melanin synthesis inhibitor. It has skin-brightening, anti-inflammatory, and photo protectant properties, which help to even-out and improve overall skin tone.
• Peach Kernel Oil, Jojoba Seed Oil, Glycerin, Caprylic/Capric Triglyceride: These cushioning ingredients form a gel-oil base, a protective and nourishing buffer for the aforementioned acids to do their job without causing excess irritation. Think of them like gutter bumpers on a bowling lane.
• Wakame Bioferment Advanced (Undaria Pinnatifida Cell Culture Extract): This unique seaweed-derived active is found in cultured wakame cells. It contributes to cell longevity by minimizing cellular damage within the mitochondria, which helps prevent the appearance of premature aging.
• AcquaSeal Algae (Chlamydomonas reinhardtii extract): Derived from a particularly robust green algae that can thrive in extreme environments, this oil-soluble active produces a bioactive complex of lipids and fatty acids that renew and hydrate cells to promote cell proliferation and anti-inflammatory benefits.
• N-Acetyl Glucosamine: A stable and effective form of biofermented glucosamine, this skin-identical ingredient helps reduce hyperpigmentation, increase the skin’s water content with hyaluronic acid, and maintain its barrier functions.
• Magnesium: This mineral helps soothe inflammation in skin, protecting against free radical damage, and is necessary for the enzymes that regulate cell turnover and repair.
• Antioxidant Blend: Turmeric Root Extract: a highly-soothing antioxidant that interrupts trigger signals in surface cells that lead to irritation. Ginkgo Biloba Extract: a potent antioxidant that protects skin from signs of premature aging and inflammation. Oat Kernel Extract: This super-soothing antioxidant is loaded with beta-glucan and lipids to protect and cushion skin. Melia Azadirachta (neem) Leaf Extract: This antioxidant has anti-microbial properties that diminish the population of harmful microbes on the skin's surface, reducing inflammation and calming the skin.
