What Is Alpha-Arbutin?
Alpha-Arbutin (INCI: Alpha-Arbutin; CAS 84380-01-8) is a naturally derived, water-soluble glycoside of hydroquinone — a fine white crystalline powder with purity of 99% and above. As the more stable and potent isomer of arbutin, it has become a benchmark brightening active for premium skincare and dermo-cosmetic formulations seeking visible tone correction without the irritation associated with free hydroquinone.
How It Works
Alpha-Arbutin acts as a reversible, competitive inhibitor of tyrosinase, the key enzyme that drives melanin synthesis. By selectively blocking this step, it reduces the formation of new pigment and helps fade existing discoloration — including sun spots, melasma, and post-inflammatory marks — while leaving healthy melanogenesis largely undisturbed.
Unlike many legacy brighteners, Alpha-Arbutin remains stable across a wide pH range and penetrates the stratum corneum efficiently at low use levels (typically 1–2%), delivering a gentler, more predictable brightening curve that suits daily and sensitive-skin routines alike.
5 Key Application Areas
- Brightening serums & essences — daily radiance and luminosity boosters.
- Dark-spot & hyperpigmentation correctors — targeted tone-evening treatments.
- Anti-aging & even-tone creams — day and night moisturizers with visible clarity benefits.
- Post-acne mark & melasma formulas — calming, pigment-reducing actives for compromised skin.
- Sensitive-skin tone-up products — a mild alternative to hydroquinone in clean beauty lines.
