A targeted exfoliating treatment built around glycolic acid — the smallest AHA molecule in skincare. That smaller size means it penetrates pore lining faster and deeper than other AHAs, dissolving the compacted debris behind blackheads and maturation arrest acne (those stubborn, skin-colored bumps that surface exfoliation alone can't touch). Available in 5% and 10% strengths to match your skin's tolerance and congestion level. Show more
