Hyperpigmentation Risk Checker

Does Alpha Arbutin Cause Hyperpigmentation?

Evidence-based guidance on alpha arbutin and its risk of triggering or worsening dark spots, melasma, and post-inflammatory hyperpigmentation.

Risk level
LOW risk

Alpha arbutin is a gentler hydroquinone derivative that inhibits tyrosinase. It is generally well tolerated, though it can release small amounts of hydroquinone in the skin, so monitoring is sensible.

How it can affect pigmentation

  • Tyrosinase inhibition without the potency of hydroquinone
  • Low irritation potential
  • Possible slow hydroquinone release with degradation

Usage advice

A lower-risk brightening option suitable for leave-on day or night products. Patch testing is still recommended.

Recommendations

  • Use morning or evening.
  • Pair with niacinamide or vitamin C for synergistic brightening.
  • Always use sun protection if your skin tends to hyperpigment; we recommend a zinc oxide sunscreen.
