From the perspective of traditional Chinese medicine, watermelon rind has a diuretic effect, which is a drainage effect, and the skin needs to maintain moisture. Using watermelon rind may be counterproductive.

From the nutritional perspective of Western medicine, there may be such a statement, but it is only based on the ingredients contained in watermelon rind. That is a serious mistake. Any beneficial or harmful ingredient requires the coordination of other ingredients. If you ignore the interaction of ingredients, it is a wrong understanding.
