MARIANO BUSSO: Sure. The sun has visible light
and invisible light. Within the invisible light we have the ultraviolet
light A and ultraviolet light B, UVA and UVB. They both produce suntan,
sunburn, premature aging, skin cancer, and also allergies and deterioration
of the immune system. The UVA penetrates the skin deeper, so it can
be harmful, and it’s more related to premature aging. UVB can be
filtered out through glass windows, whereas UVA not as much. Therefore
we see a lot more aging or even skin cancers on the left side of our body
because of our driving habits, we get more sun through the windows in our
cars.
SUSAN CINGARI: So essentially, should we wear sunscreen
in the car?
MARIANO BUSSO: We should wear sunscreen before we
leave home. As a matter of fact, we receive about one to two hours
per day of indoor tanning without even noticing it. So first thing
in the morning we should apply sunscreen.
STEVEN SHAPIRO, MD: One thing about damage to the
skin and skin cancer, most people feel they have their sunburn and the
sunburn goes away and the skin goes back to normal. But the skin
actually has memory in it and it can remember that damage, and years later
it can cause skin cancer.
SUSAN CINGARI: Speaking of UVA and UVB rates, a
lot of people are saying, “Okay, we know we’re not supposed to gout in
the sun so we’re going to go to a tanning salon.”
What about tanning salons? Talk to me about UVA
and UVB rates, if there are any, in the tanning salon.
