While drinking lemon water is often touted as a skin-whitening solution, there's no scientific evidence to support this claim.
Lemon juice contains citric acid, which is a natural bleaching agent. However, the amount of citric acid in lemon water is too diluted to have any noticeable effect on skin pigmentation.
While lemon juice can lighten skin when applied topically, ingesting it won't have the same effect.
The benefits of drinking lemon water are primarily related to hydration and its potential antioxidant properties.
To achieve noticeable skin lightening, consider using products containing proven ingredients like hydroquinone or kojic acid under the guidance of a dermatologist.
Remember, healthy skin is radiant skin. Focus on a balanced diet, adequate hydration, and proper skincare routines for optimal results.
