Can drinking lemon water whiten the skin?

Drinking lemon water may have some skin whitening effects, but one should not rely solely on lemon water for skin whitening, as the actual effectiveness varies among individuals. Lemons are rich in vitamins and are considered excellent for beauty care. Particularly, the vitamin C contained in lemons can inhibit melanin production, helping prevent and reduce skin pigmentation, thereby achieving a skin whitening effect. Moreover, lemons are rich in citric acid, which can mildly exfoliate the skin, promote skin metabolism, help brighten skin tone, and also contribute to skin whitening. In addition, lemons contain flavonoids that exert antioxidant effects, neutralize free radicals, protect skin cells from UV-induced free radical damage, and thus reduce melanin deposition. It is advisable to drink lemon water in moderation daily. After drinking lemon water, it is important to apply sunscreen to prevent skin pigmentation caused by UV exposure. Skin whitening cannot be achieved solely by drinking lemon water. It also requires regular skincare routines, the use of medical-grade skin whitening products, and aesthetic treatments such as laser whitening and photorejuvenation. If skin problems on the face are severe, prompt medical consultation and treatment are recommended.
