Gently renew and hydrate with our 7% Polyhydroxy treatment tonic — powered by gluconolactone and lactobionic acid for next-level exfoliation that’s kinder than traditional AHAs. This leave-on tonic smooths texture, brightens dullness, fades fine lines, reduces hyperpigmentation and strengthens the skin barrier while delivering deep, long-lasting moisture. Ideal for sensitive, dry, rosacea-prone or mature skin craving radiance without stinging or redness.
