Science behind this peeling solution: Unlike physical exfoliators (scrubs brushes etc.) commonly used in facials this gentle yet powerful 32% AHA/PHA/BHA chemical exfoliant trio promotes cell turnover and clear pores without causing micro-tears or damaging the skinâs natural barrier. 25% AHA (Glycolic Acid Lactic Acid Mandelic Acid) delivers superficial peeling by dissolving away the dead skin cells present in the upper skin layer revealing a bright even skin tone. 5% PHA not just exfoliates but also doubles up as humectant and moisturiser. Because of its larger molecule size compared to Glycolic acid (molecular weight 178 vs. 76 for Glycolic acid) it penetrates the skin slowly hence offering lesser irritation. Lastly 2% BHA (Salicylic acid) unclog pores by breaking bonds formed by dead cells and flushing out skin debris & oils reducing blackheads and whiteheads.
