About this product
Chemical exfoliant with 7% glycolic acid to dissolve dead skin cells and whiteheads. Gentle enough for regular use, revealing smoother and brighter skin over weeks.
Why AHA 7% (Glycolic Acid) works
AHA 7% (Glycolic Acid) exfoliates by breaking desmosomes between dead skin cells, improving tone, texture, and product absorption.

Concerns addressed
AHA/BHA chemical exfoliation smooths rough patches, while hyaluronic acid plumps for a refined finish.
BHA, niacinamide, and clay-based products help minimise pore appearance by controlling sebum.
Look for BHA (salicylic acid) to unclog pores and niacinamide to calm inflammation.
Niacinamide, vitamin C, and AHAs gently fade pigmentation with consistent use.
