Alpha Arbutin

INCI: Alpha-Arbutin · Bearberry-derived glycoside

AlphaForm Used (vs. Beta)

Mechanism of Action

Alpha Arbutin is a plant-derived glycoside that competitively inhibits tyrosinase — the rate-limiting enzyme in melanin synthesis.¹² The alpha configuration is structurally more stable and a stronger tyrosinase inhibitor than the more commonly used beta form.²

Research Evidence

Key finding: Studies in cultured skin cells and tissue models found that arbutin inhibits tyrosinase activity and reduces melanin production.¹² Visible change from consistent use typically emerges over 4 to 12 weeks.
Property Detail
Depigmentation Competitive tyrosinase inhibition, blocking new melanin production at the source.¹
Daily-Use Profile Formulated for ongoing daily use rather than a short, cyclical course.¹

Formulation Rationale

Alpha Arbutin and Niacinamide interrupt pigmentation through different stages of the same pathway — production versus transfer — which is the basis for using both together rather than relying on a single mechanism.

Usage Protocol

Included at an effective concentration in the Face Serum, applied 2–3 drops twice daily.

Safety Profile

Generally well tolerated. Daily sunscreen is strongly recommended alongside any brightening active, since unprotected UV exposure can generate new pigmentation that offsets progress.

Where You'll Find It

Niacinamide 10% Face Serum (₹649)

Frequently Asked

How long before I see results?

Most people notice a gradual change over 4 to 12 weeks of consistent twice-daily use — pigmentation fades gradually rather than overnight.

Bottom line: Formulated for consistent daily use rather than a short, aggressive course — steady, gradual improvement in tone with regular application.
