Unfortunately, many adults don't outgrow the adolescent problem of having difficult skin. Men and women in their twenties, thirties and beyond can still suffer from acne and either oily or dry skin that results in frequent breakouts. To clear your skin, the best tip to follow is to increase your water consumption. Be sure to drink a minimum of 64 ounces of water each day, and more if you live in a hot or humid climate. This can help detoxifying your body and results in clearer skin.
