Claims on social media that using ENO powder with lemon can make the skin fairer are not true. ENO is a medicine used to relieve indigestion and stomach acidity. It is not designed for use on the skin. Lemon juice is highly acidic and can irritate the skin, especially when exposed to sunlight. Mixing and applying them to the face may disturb the skin?s natural balance and cause redness, a burning sensation, dryness, itching, or even chemical irritation in some people. It may also increase the risk of dark patches after sun exposure. There is no scientific evidence that this mixture improves skin fairness. Skin colour is mainly determined by genetics and cannot be safely changed using home remedies. For healthy skin, it is better to use gentle skincare products, apply sunscreen regularly, and consult a dermatologist for any pigmentation concerns.
