What it does
A gentle brightening active that interrupts excess melanin production to fade the appearance of dark spots and even skin tone.
Best for
Dark spots, post-acne marks, melasma, and uneven tone. Well tolerated as a gentler alternative to hydroquinone.
What is alpha arbutin?
Alpha arbutin is a gentle brightening active that fades the appearance of dark spots and evens skin tone. It works by interrupting tyrosinase, the enzyme that drives excess melanin, and it is often chosen as a gentler alternative to hydroquinone.
Because it targets pigment specifically, it is one of the more reliable ingredients for the look of dark spots and post-acne marks.
What does alpha arbutin do for skin?
Alpha arbutin reduces the appearance of hyperpigmentation and helps even overall tone.
In a split-face clinical study, topical alpha arbutin reduced the appearance of melasma effectively and with good tolerability.
It layers well with vitamin C and niacinamide for a brightening routine. Results build over weeks, and daily sunscreen is essential, since sun exposure undoes brightening progress.
Who should use alpha arbutin?
Alpha arbutin suits anyone with dark spots, melasma, or uneven tone who wants a gentle brightener. It is well tolerated across skin types, including sensitive skin that finds hydroquinone too harsh.
Evidence
Topical alpha arbutin reduces the appearance of melasma and hyperpigmentation, performing well in comparative clinical studies.
