Kosi Multi Acid Mask

As with any effective skincare regimen, there is always room for improvement.
When it comes to dealing with dullness, splotches, and other obvious symptoms that you're not drinking enough water (who has the time?), this mask is your go-to project manager or concierge.
This isn't just another exfoliating resurfacer: Kosi Multi Acid Mask reaches down to the cellular level to help prevent future skin damage.
This composition aims to restore skin's vitality, radiance, and vigor by combining a multi-purpose acid combination with antioxidants that heal damage and algae and seaweed that purify the water.

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 smaller-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. Gingko 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. 

Apply generously to a cleansed face.
Rinse well with warm water and apply Grand Amino Cushion Cream.
Use twice a week before bedtime. 
Skip any other AHA or exfoliating products when using this mask. It's usual to feel tingling or slight redness after application.
Always use sunscreen the next day (but also every day in general).
For external use only. Avoid contact with eyes.

SUNBURN ALERT: This product contains an alpha hydroxy acid (AHA) that may increase your skin’s sensitivity to the sun and particularly the possibility of sunburn. Discontinue use immediately if irritation occurs & consult a physician. Use sunscreen daily where AHA has been applied for a week afterwards. Product contact with skin must be of limited frequency or duration.
