Water helps the body flush out toxins and transport nutrients to the body. Drinking water puts less strain on the skin organ to flush out toxins. The recommended amount of water you should drink is at least half your bodyweight in ounces of water( a 140lb. individual should drink 70 ounces/day ). While water alone will not eliminate your acne it will greatly assist your skin in remaining healthy and that will be one portion of the pie in fighting acne.
