Does Physical Scrubs Cause Hyperpigmentation?

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

Risk level
HIGH risk

Abrasive particles can create microtears and inflammation, particularly on darker skin tones and active acne. This mechanical damage is a direct trigger for post-inflammatory hyperpigmentation.

How it can affect pigmentation

  • Mechanical abrasion and microtears
  • Inflammation and PIH
  • Worsening of active breakouts and barrier damage

Usage advice

Physical scrubs are high risk for pigmentation-prone skin. Chemical exfoliation (e.g., low-dose AHAs or PHAs) is usually a gentler alternative.

Recommendations

  • Use very gentle pressure and only 1-2 times per week if you choose to scrub.
  • Avoid on active acne, broken skin, or inflamed areas.
  • Consider switching to a chemical exfoliant.
  • Always use sun protection if your skin tends to hyperpigment; we recommend a zinc oxide sunscreen.
