Alpha-Arbutin

Alpha-Arbutin — one of the most scientifically validated and safe lightening molecules. More effective than regular arbutin, it inhibits tyrosinase (the enzyme that produces melanin), evenly brightening skin tone without aggressive bleaching.

What is it?

Alpha-Arbutin — a synthetic glycoside of hydroquinone (4-hydroxyphenol-α-D-glucopyranoside). The alpha form is more stable and effective than beta-arbutin (natural arbutin from cranberries). Concentration: 0.5–2% in most products, effective from 0.5%. INCI name: Alpha-Arbutin.

Key component in serums and creams for pigmentation: age spots, post-acne PIH, melasma, uneven skin tone. More effective than regular arbutin due to the alpha configuration, which slows down enzymatic breakdown.

Key Benefits

✦
Inhibition of tyrosinase — effective brightening
Alpha-Arbutin inhibits tyrosinase — the key enzyme in melanin synthesis. Reduces the formation of new pigment in melanocytes. Clinical studies confirm a visible effect at 0.5–1% concentration within 4–8 weeks.
◈
Correction of post-acne and hyperpigmentation
Effective for PIH (post-inflammatory hyperpigmentation) — darkening after acne inflammation. Gradually brightens existing spots. Best results when combined with vitamin C, niacinamide, or retinol.
✧
Safety and tolerability
Unlike hydroquinone (potentially toxic with prolonged use), alpha-arbutin is safe for long-term use. Well-tolerated by sensitive skin. Stable in formulas with pH 3.5–6.5.

Alpha-Arbutin vs Arbutin vs Kojic Acid

Beta-arbutin (natural) is less effective — it breaks down faster. Alpha-arbutin is more stable and stronger. Kojic acid is effective but less stable in formulas and can be irritating. Alpha-arbutin is the safest choice for long-term pigmentation correction.
