Dr. Jami Reaves' Tips for Healthy, Active Skin

Exercise is great for your mind and body, but regular workouts can cause some skin issues. Follow these tips to help avoid common skin problems.

How do you apply sunscreen to sweaty skin?

• Some new sunscreens are formulated for use on wet skin, such as Neutrogena Wet Skin and Coppertone Wet and Clear. Unless your sunscreen is specifically made for wet skin, however, dry your skin with a towel before applying.

What are the best fabrics for working out?

• Moisture-wicking fabrics, such as nylon or polyester blends, will minimize irritation and keep you dry.

Is it best to cover cuts or let them breathe?

• Cuts heal 40% faster when covered with a protective product, such as Vaseline or Aquaphor, and a bandage. I don't recommend antibiotic ointments, which can cause skin problems and are only minimally effective.

What can I do if my clothes or gear chafe my skin?

• A fellow dermatologist and marathoner recommends Body Glide Chafing Stick orMission Skincare High-Performance Anti-Friction Cream to help with chafing.

Does sweat cause acne?

• Athletic activities can trigger both sweating and increased oil production. Whenclothing or gear (such as sweatbands) rubs against your skin, the irritation can cause a breakout. Reduce the likelihood of breakouts by avoiding tight-fitting clothing and accessories and showering shortly after a workout.

Should I be worried about callouses?

• No, callouses don't need to be treated unless they cause discomfort. Your doctor can remove them or you can treat them with an over-the-counter salicylic acid ointment.

Should I pop a blister?

• It's okay to prick the blister with a sterile pin to drain the fluid, but the top should be left intact. You don't need a bandage unless it feels better covered.

How do I avoid athlete's foot?

• I advise patients prone to these infections to apply a powder such as Zeasorb daily before putting on shoes. Keep your feet dry, and spray shoes two or three times a week with an antifungal spray such as Tinactin.
