Does Salicylic Acid Cause Hyperpigmentation?

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

Risk level
MODERATE risk

Salicylic acid is oil-soluble and effective for acne and pore exfoliation. It can be drying and mildly irritating, which may worsen hyperpigmentation if the skin barrier is compromised.

How it can affect pigmentation

  • Keratolytic exfoliation and dryness
  • Barrier disruption at high concentrations or overuse
  • Post-inflammatory hyperpigmentation from acne treatment irritation

Usage advice

Use in cleansers, toners, or spot treatments. Start with low strength and avoid layering with other strong actives until tolerance is established.

Recommendations

  • Use as a spot treatment or short-contact cleanser first.
  • Moisturize after use to protect the barrier.
  • Always use sun protection if your skin tends to hyperpigment; we recommend a zinc oxide sunscreen.
