Alpha Arbutin for Melasma

A safer, slower-acting alternative to prescription-strength dark-spot faders. Built for long-term use without irritation.

Why it works for Melasma

Fades patches by slowing pigment production. It is a gentler relative of hydroquinone and does not release free hydroquinone into the skin, so it suits long-term upkeep. There is clinical evidence for 2% alpha-arbutin in melasma and in dark marks left after inflammation, especially in Asian and Latin-American skin.

How Alpha Arbutin works

Hydroquinone-glucoside that competitively inhibits tyrosinase without releasing free hydroquinone.
