Hyperpigmentation Risk Checker

Does Mandelic Acid Cause Hyperpigmentation?

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

Risk level
LOW risk

Mandelic acid is a larger-molecule AHA that penetrates more slowly than glycolic acid. It is generally less irritating and a safer choice for hyperpigmentation-prone skin.

How it can affect pigmentation

  • Gentle exfoliation with slower penetration
  • Lower irritation and photosensitization risk than glycolic acid
  • Brightening through cell turnover

Usage advice

Mandelic acid is a good introductory AHA for darker skin tones. Use at night and wear SPF during the day.

Recommendations

  • Start with 1-2 uses per week at night.
  • Apply SPF every morning.
  • Always use sun protection if your skin tends to hyperpigment; we recommend a zinc oxide sunscreen.
