Skin & Beauty: Exercise Your Body -- and Your Skin (cont.)

"There's a lot of indirect evidence that shows that when you exercise your level of stress diminishes. So your adrenal glands are producing less of these male-type hormones that are part of any acne flare-up," says David Berman, MD, medical director and dermatologic/cosmetic surgeon at the Berman Skin Institute, Palo Alto, Calif., and former chief of dermatology at Santa Clara County Hospital.

If you want proof, says Berman, think about any situation that increased your stress level -- finishing a term paper or job project on deadline -- and you're likely to recall a breakout.

"Almost everyone's skin flares when they are under stress but especially those who already have acne," says Berman.

Exercise, he says, can help control it. "By reducing stress, it tends to quiet the adrenals. There is less hormone output which in turn helps control acne," says Berman.

According to dermatologist David Goldberg, MD, regular exercise also increases sweating, which in turn can unclog pores and have a positive effect on breakouts.

"In the long run, people who exercise have a better complexion overall. If they have acne, it's better controlled, and if they have occasional breakouts they are definitely less severe, and clear quicker and easier," says Goldberg, director of Skin Laser and Surgery Specialists of N.Y./N.J., and a clinical professor of dermatology at Mt. Sinai Medical Center in New York City.

Kunin agrees and says this same hormone-reducing activity can also benefit your hair.

"Anything that controls the amount of male hormones your body produces can impact not only skin, but also androgenic hair loss. Anything you can do to reduce the production of these hormones is going to have beneficial results on both skin and hair," Kunin tells WebMD.

While we don't often think of exercise has having any specific anti-aging effects on skin, experts say it most definitely does.

One is by influencing the natural production of collagen, a kind of connective tissue that plumps your skin and gives your face the bloom of youth.

"Our fibroblasts, which are the collagen-producing cells in the skin, became fewer in number and they become lazy as we get older," says Kunin. Skin becomes less firm, drier, and even more wrinkled.

However, add an exercise routine to your beauty regimen and Kunin says you infuse skin cells with oxygen as well as other nutrients. Both set up ideal conditions for collagen production.

"Give your skin what it needs to function properly and it's going to behave better and look younger," says Kunin.

And when it comes to looking good, Kunin says certain exercises can even help break up pockets of cellulite -- that cottage cheese-like skin on the buttocks, backs of thighs, and upper arms. This forms, she says, when fibrous connections in skin are pulled tighter, leading to puckering in pockets of fat.

By toning and pulling the muscles with workouts such as Pilates or weight training, Kunin says you reverse that tension, which reduces the appearance of cellulite.

"If you are properly hydrating yourself during exercise you will get better blood flow."
