Holifrog Kosi Multi-Acid Mask is a resurfacing and replenishing face mask that goes beyond the superficial layers, recharging the skin back to its most vibrant, refreshed, and energised self.

Not just another exfoliating resurfacer it contains a multi-functional acid blend, repairative antioxidants, and the power of algae and seaweed in this gel-oil base.

Brightens skin overall, helping diminish hyper-pigmentation and dullness, while restoring vibrancy to skin tone. The multi-tasking ingredient profile exfoliates, hydrates, repairs, and protects against inflammation.

Suitable for all skin types, especially in times of visible fatigue or dullness.



Key ingredients in Holifrog Multi-Acid Mask include:

  • 10% AHA Blend - Chemical exfoliators, Lactic, Mandelic, Malic Acids, gently break down debris and dead skin cells on the skin's surface. 
  • 8% PHA (Gluconolactone) - This acid exfoliator is a multi-tasker, it not only does what AHAs can do (but gentler), but also hydrates the skin with its humectant properties.
  • 2% BHA (Salicylic Acid) - This oil-soluble acid penetrates pores to more deeply clear the skin targeting blackheads and whiteheads.
  • Diglucosyl Gallic Acid - Transforms into Tri Hydroxy Benzoic Acid, when activated by your skin’s microbiome. It has skin-brightening, anti-inflammatory, and photo protectant properties, which help to even-out and improve overall skin tone. 
  • Wakame Bioferment Advanced - This unique seaweed-derived active is found in cultured wakame cells. It contributes to cell longevity helping prevent the appearance of premature ageing. 

Antioxidant Blend

  • Turmeric Root Extract - a highly-soothing antioxidant that interrupts trigger signals in surface cells that lead to irritation.
  • Oat Kernel Extract - This super-soothing antioxidant is loaded with beta-glucan and lipids to protect and cushion skin.
  • 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
