Get the appWhat it does
Alpha arbutin is hydrolyzed in the skin to hydroquinone, which inhibits tyrosinase enzyme activity and reduces melanin production. It works gradually over weeks to months and is considered a gentler alternative to hydroquinone while offering similar brightening effects. Results are modest but consistent with regular use.
Benefits
- Fades post-inflammatory hyperpigmentation and melasma with sustained use
- More stable and gentler on skin than direct hydroquinone application
- Works synergistically with exfoliants and vitamin C for enhanced results
- Generally well-tolerated across most skin types
Who it suits
- Hyperpigmentation and dark spots
- Melasma-prone skin
- Post-inflammatory hyperpigmentation
- All skin types including sensitive
How to use
Apply to clean skin in serums or moisturizers, typically once or twice daily. Pair with broad-spectrum SPF 30+ during daytime as brightening products make skin more sun-sensitive.
Pairs well with
Vitamin C (enhanced brightening), AHAs/BHAs (improved penetration), Niacinamide (brightening synergy)
Be careful pairing with
High-concentration benzoyl peroxide (may degrade)
Safety & cautions
Results are gradual; expect 2-3 months minimum for visible improvement. Avoid excessive sun exposure as UV can trigger melanin production; always use SPF. Keep concentration typically under 2% in finished products.
