Alpha Arbutin

Precision brightening without irritation

Corrects

Inhibits melanin production to fade existing hyperpigmentation.

Prevents

Blocks new dark spots from forming with continued use.

Gentle

Safer and more stable than traditional hydroquinone treatments.

What it is

A glycosylated derivative of hydroquinone, naturally occurring in plants like bearberry and pear. It delivers similar brightening benefits with a significantly better safety profile.

How it works

Alpha Arbutin inhibits tyrosinase, the enzyme responsible for melanin production. By slowing this process, it gradually fades existing dark spots and prevents new hyperpigmentation from forming — with a much lower irritation risk than hydroquinone.

hydroquinone — Alpha Arbutin delivers comparable brightening without the regulatory restrictions or irritation risk.

Why we chose it

We wanted a brightening agent with real efficacy but without hydroquinone’s regulatory restrictions and irritation potential — Alpha Arbutin threads that needle precisely.
