For many people, the purpose of tanning is obvious: bronze is beautiful. But although a deep tan may get you compliments this summer, too much exposure is likely to give your skin trouble down the road, causing premature wrinkling and other problems. Our panel of dermatologists will offer some expert tips on keeping you skin in top shape.

STEVEN SHAPIRO, MD:  I’d like to start with this one.  Years ago we thought that UVB caused skin cancer, and we remember UVB for bad.  And the tanning salons, to that point, were about 98%.  So what happened is they switched to UVA and now they’re about 98% UVA.  Later on we found out that UVA caused skin cancer, as well.  So what happened is that we know that tanning salons contain about 98% UVA, 2% UVB, both rays cause skin cancer, therefore the tanning salons cause skin cancer.  In fact, I believe it was this week, the FDA listed sunlamps on their list of carcinogens.  So we do know that tanning salons do cause skin cancer.

MARIANO BUSSO:  People need to understand that when you have a tan, the skin is sending is sending you a messaging, which is, “I’m getting darker to protect from radiation.”  So it’s a protective mechanism as opposed to a health mechanism.  So every time you have a suntan, that’s bad.

STEVEN SHAPIRO, MD:  One of the things I tell my patients in the room, most people say, “I don’t go out in the sun, I don’t have any skin cancer, I don’t have any sun damage,” and I tell people, “Look at the outer part of your arm.”  And on the outer part of their arm you’ll see freckling, you compare it to the inside of your arm, you don’t see quite as much, that’s a measure of your own sun damage.  That will also show people, too, that they do have some background sun that they’re getting, and it’s the same sun walking down the street that it is at the beach. Most people feel you have to be at the pool or the ocean to get sun, that’s not true.

MARIANO BUSSO:  Yes, that’s not true.  I see people with major suntans, I say, “You’ve been in the sun?” “No.”  “But you have a suntan.”  “Well, I run from eight to nine.”  Right.  People think that the bad rays are between ten and four.

All the sun exposure is going to harm your skin, it doesn’t matter the time of the day.  Of course, you’re going to get a lot more harmful radiation at noontime, it has the highest index value, but at seven o’clock at night or in the morning, you’re still going to have harmful rays.
