Product Advantage
Superior Tyrosinase Inhibition
α-Arbutin exhibits 10‑15× stronger tyrosinase inhibition than β-arbutin (IC₅₀ = 0.35 mM vs. 4.8 mM). This allows use at lower concentrations (0.2–1.0%) while achieving faster brightening results.
Keywords: alpha arbutin powder
Excellent Safety & Low Irritation
Dermatological studies confirm 0% cytotoxicity at 1% concentration (MTT assay on human melanocytes). Unlike hydroquinone, α-arbutin does not induce ochronosis or DNA damage, making it suitable for long‑term use.
Keywords: skin brightening agent
High Purity & Stability
Our α-arbutin offers ≥99.0% purity (HPLC), with heavy metals ≤5 ppm and residual solvents below ICH limits. It remains stable in formulations at pH 4–7 and up to 60°C, ensuring consistent performance.

Fast Visible Results
Clinical study (n=30, 2% α-arbutin cream, twice daily): Ideal for dark spot correction.
Keywords: arbutin for hyperpigmentation
Versatile Formulation Compatibility
Water‑soluble and non‑sticky, α-arbutin can be easily incorporated into serums, essences, creams, and masks. It synergizes with niacinamide, vitamin C, and tranexamic acid for enhanced brightening effects.

Product Uses
α-Arbutin – Multi-Application Skin Brightener
Facial Serums for Dark Spot Correction
α-Arbutin is a staple in brightening serums, where it gently fades age spots, post-acne marks, and sun damage. At 0.5–2.0%, it works well with hyaluronic acid for a hydrating, non‑irritating formula. Ideal for daily use on all skin types.

Moisturizing Creams for Even Tone
In daily face creams, α-arbutin helps prevent new pigmentation while improving overall radiance. Its water‑soluble nature blends easily into emulsions, leaving no residue. Perfect for anti‑pollution and daytime brightening creams.

Sheet Masks for Instant Glow
Added to sheet mask essences, α-arbutin delivers a concentrated brightening boost in just 15–20 minutes. It soothes hyperpigmentation without causing redness, making it suitable for sensitive skin masks.

Night Creams for Overnight Repair
In overnight formulations, α-arbutin works synergistically with retinol or niacinamide to accelerate cell turnover and fade dark spots. It remains stable at skin pH, providing cumulative brightening effects with consistent use.

Eye Creams for Dark Circles
α-Arbutin is increasingly used in eye creams to target periorbital hyperpigmentation. Its mild nature reduces the risk of stinging, while its tyrosinase‑inhibiting action lightens under‑eye shadows over time.
