Hydrated skin is healthy skin, but your serums and creams shouldn’t have to bear all the responsibility. Aside from that, your other organs need water to function properly. One simple way to calculate how much water you should be drinking every day is to take your weight in pounds, divide it by two, and drink that amount in ounces. If you’d like to be a little more advanced in your calculations, you can download an app that adjusts your recommended intake according to your activity level and weather conditions. Your diet is also important, so make sure to eat balanced meals full of essential vitamins, minerals, fats, antioxidants and other beneficial nutrients.
