Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Lemon has traditionally been used as a home remedy for body odor. Its use is rooted primarily in folk and traditional practices rather than in strong scientific validation. Lemons contain citric acid, which can lower the skin’s pH. This acidic environment is less hospitable to odor-causing bacteria, which thrive in the more neutral pH of sweat. People have historically applied lemon juice directly to the skin, especially underarms, to help neutralize body odor and as a natural alternative to commercial deodorants.

However, while there is some plausibility to the mechanism—since lowering skin pH can inhibit bacterial growth—there are limited clinical studies that directly assess lemon’s efficacy for body odor management. Most of the evidence is anecdotal or based on the general antibacterial properties of citric acid and lemon juice. Some laboratory studies have demonstrated that lemon juice has antimicrobial effects, but these are not specific to the context of body odor in humans.

Therefore, while the traditional use of lemon for body odor is widespread, and its acidic and mildly antibacterial properties offer a theoretical basis, scientific evidence supporting its effectiveness is weak and mostly indirect. Individuals should also be cautious, as lemon juice can irritate sensitive skin and increase sensitivity to sunlight.
