Alpha Arbutin

Overview

Alpha Arbutin is a highly stable, water-soluble skin brightening active that inhibits tyrosinase enzyme activity to reduce melanin production. It is considered a safer and more effective alternative to hydroquinone.

INCI Name

Alpha-Arbutin

Key Benefits

• Inhibits melanin synthesis — reduces dark spots and hyperpigmentation
• More stable and effective than Beta-Arbutin
• Brightens overall skin tone without bleaching
• Suitable for all skin types including sensitive skin
• Synergistic with Niacinamide, Vitamin C, and AHAs

Recommended Applications

• Brightening serums & ampoules
• Day & night creams
• Spot correctors
• Toners & essences
• Eye creams

Recommended Use Level

0.5–2% in the aqueous phase (pH 3.5–6.5 for optimal stability)

Solubility & Phase

Water-soluble. Dissolve in warm water (40–50°C). Add at cool-down phase (below 40°C) to preserve activity.

Certifications & Grade

• Cosmetic active grade
• >99% purity (HPLC)

Storage

Store in a cool, dark place (below 25°C). Keep away from light and humidity. Shelf life: 24 months in sealed packaging.

Commonly Used With

• Niacinamide (Vitamin B3) — the most powerful brightening duo; dual melanin inhibition pathway
• Glycerine 99.7% — aqueous base for brightening toners and essences
• Propylene Glycol — co-solvent to aid Alpha Arbutin dissolution

Frequently Asked Questions

What is the difference between Alpha Arbutin and Beta Arbutin?

Alpha Arbutin is more stable, more effective, and more expensive than Beta Arbutin. It has a stronger tyrosinase inhibition effect and is the preferred form in premium brightening formulations.

Can Alpha Arbutin be used with Niacinamide?

Yes — this is one of the best combinations in cosmetic formulation. Niacinamide and Alpha Arbutin inhibit melanin through different pathways, making them highly synergistic for brightening and hyperpigmentation treatment.

Is Alpha Arbutin safe for daily use?

Yes. At 0.5–2%, Alpha Arbutin is well-tolerated for daily use by all skin types, including sensitive skin. It does not cause the irritation associated with hydroquinone.

What pH is best for Alpha Arbutin?

Alpha Arbutin is most stable and effective at pH 3.5–6.5. Avoid formulating above pH 7 as it may degrade into hydroquinone over time.

How do I dissolve Alpha Arbutin powder?

Dissolve in warm water (40–50°C) or use Propylene Glycol as a co-solvent. Add to the formulation at cool-down phase (below 40°C) to preserve stability.
