The Claim

Massaging lemon juice on a scar for about 10 minutes two to three times per week lightens the skin and helps remove old scars.

Verified by Lenz ·

The Short Version

The evidence does not support lemon juice as a reliable way to lighten or remove old scars. Research on scars favors other treatments, while studies on AHAs or topical vitamin C involve standardized formulations, not raw lemon juice. Citrus can also irritate skin and cause phototoxic reactions that may worsen discoloration.

Caveats

  • Do not confuse discoloration with scar removal: even if pigmentation changes, established scar tissue is not shown to be removed by lemon juice.
  • Evidence for chemical exfoliants or vitamin C serums does not apply to raw lemon juice, which has unpredictable strength and safety.
  • Lemon on skin can cause irritation, burns-like phototoxic reactions, and post-inflammatory hyperpigmentation, especially with sun exposure.
