A dermatologist and a cosmetic chemist debunk 19 skin-care myths

A cosmetic chemist and board-certified dermatologist debunk 19 of the most common myths about skin care. They explain how drinking water doesn't necessarily make your skin look better and how you can't really shrink your pores. They also debunk the idea that acne is only a puberty problem. In fact, adult acne is quite common and treatment usually takes about 6 to 8 weeks for results to show.
