After eating fruit, some people casually stick the peels on their faces in order to make their skin delicate and smooth. Unexpectedly, pimples appear. Lately, quite a number of such patients have been seen by Dr. Liu Xiangnong, director of the Department of Dermatology at Nanjing Military Region Fuzhou General Hospital.
Because, some fruits and vegetables contain photosensitive substances, such as aloin in fresh aloe vera and mangiferin in fresh mangoes. When these are directly applied to the skin, they absorb light and cause an allergic reaction that leads to local swelling.
In many people's minds, using juice squeezed from fruit they buy themselves and applying it to the skin is more natural and safe than using skincare products with chemical additives. The vitamins, pectin, green tea phenols, etc., in these fruits can allow the skin to directly enjoy a "nutritious feast". However, if the wrong fruit is chosen, this method can instead harm the skin. Some fruits, such as lemons, tomatoes, and strawberries, are very acidic and can have a "bleaching" effect on the skin. Applying their juice to the face can actually make the skin rougher.
