1. Apply buttermilk and rub the portion that is exposed to the skin tan. The lactic acid in the buttermilk will clean your skin and shed the upper layer. later you will get the regular colour of the skin.
2. Cucumber with lemon juice is the other medicine which can clean your skin and bring back the same to the normal condition. While the cucumber will soothe and cool your skin, the Lemon juice acts as a bleaching agent and removes the tan slowly. The same can be used for the face also.
3. Sandalwood powder with rose water is also good for the skin. Sandalwood has the soothing effect, while the rose water has got the cleaning effect. Both should be made as a paste and applied.
4. Oatmeal and honey together can be grounded and used as a paste. This will also remove the tan and clean the skin to a larger extent. The paste can be applied and then peeled off.
5. Watermelon can be rubbed on the skin and it acts as an antioxidant. It soothes the skin and removes the bad portions. Just use watermelon pieces as a scrub and it removes the tan to a larger extent.
