"Exercise can improve your skin, as long as you are breaking a sweat," said Dr. Jeanine Downie, a board certified dermatologist. "What that means is that you must raise your heart rate and boost your circulation. Boosting your circulation is what improves your skin tone on a physiological basis — that is why they call it 'working up a good sweat.'"
She said that exercise improves your heart, skin, lungs, and, of course, the function of your body's largest organ: the skin! Pictured above is Sugarmat Blue Orchid Botany Yoga Mat ($72), which is pretty enough to inspire anyone to assume the Downward Dog position!
