Will lemon juice actually work to lighten eczema marks?

Lemon juice has natural bleaching properties due to its citric acid content, which may help lighten hyperpigmentation, including eczema marks. However, it can also be irritating to sensitive skin, potentially worsening eczema symptoms. It's essential to perform a patch test and consult a dermatologist before using lemon juice as a treatment. Other gentle, dermatologist-recommended options may be safer and more effective for treating eczema scars.
