“Massaging lemon juice on a scar for about 10 minutes two to three times per week lightens the skin and helps remove old scars.”
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.
“Topical application of lemon juice lightens human skin tone.”
The evidence does not show that raw lemon juice is a reliable way to lighten human skin tone. Laboratory studies on citric acid or lemon extracts suggest possible pigment-related effects, but that is not the same as proven benefit from applying lemon juice to skin. Direct evidence is limited, and real-world use more often raises concerns about irritation, phototoxicity, uneven lightening, or darker post-inflammatory pigmentation.
