You've probably heard that in order to keep your skin hydrated, you must drink eight glasses of water each day. Is drinking water good for your skin? It's no surprise that your body needs water and is a better alternative than any other liquid you choose to put into your body. Although, contrary to popular belief, there is no actual medical or scientific study that correlates healthy and hydrated skin to drinking a fixed amount of water everyday. Drinking a glass of water does not directly correlate with the appearance of your skin. If you're feeling thirsty, it is because the entirety of your body needs water. If your skin is feeling dry, try a moisturizer instead of drinking water.
