A 10-minute weekly peel at professional strength — glycolic, lactic, tartaric, citric and salicylic acids stacked together. Not a daily product; once or twice a week maximum, never on broken or actively irritated skin. The red colour is tasmannia fruit, not blood.
The smallest AHA molecule — 76 daltons — allowing the deepest penetration and most potent exfoliation. Dissolves desmosomes holding dead skin cells together, accelerating cell turnover. Improves texture, radiance, fine lines, hyperpigmentation and active-ingredient absorption. Used in professional chemical peels at 20–70%.
The only BHA widely used in skincare and the gold standard for acne and congested skin. Oil-soluble — penetrates sebum-filled pores to dissolve plugs and exfoliate pore walls. Dual surface + pore-level action uniquely effective for blackheads, whiteheads and inflammatory acne. At 0.5–1% in cleansers it provides daily maintenance without irritation.
The gentlest commonly used AHA — larger molecular weight than glycolic means shallower penetration and less irritation. Uniquely dual-function: exfoliates dead skin AND acts as a humectant, hydrating while it treats. Ideal first AHA for sensitive skin. At higher concentrations treats hyperpigmentation and used in professional peels.
