Can a tan signal DNA damage? YES.
Ironically, what's often called a “healthy glow” can actually be a sign of serious skin damage.
Skin vs. Sun
The sun's UV–(ultraviolet) rays easily penetrate the paper-thin epidermis. Different types of rays—UVA and UVB—cause different types of damage. Both begin immediately upon exposure. A tan is skin's attempt to shield its DNA from further damage.
|Shorter, more energetic UVB “burning” rays:
||Longer, more penetrating UVA “aging” rays:
|• Probable cause of sunburn and certain skin cancers.
• Intensity varies by time of day, season, altitude, distance from the equator.
• Fair skins are the most vulnerable.
|• Probable cause of wrinkling and other signs of premature aging, certain skin cancers.
• Intensity does not vary. 60-80% penetrate clouds, 50% pass through window glass.
Damage to DNA sets in motion a range of effects from premature aging to skin cancer.
ALL SKINS RISK DNA DAMAGE. IT STARTS LESS THAN 5 MINUTES AFTER UV-EXPOSURE BEGINS. REDNESS TAKES 8-25 MINUTES TO APPEAR.
Less than 5 minutes: DNA is damaged
The fairest skins start to turn red after less than 10 minutes of exposure. DNA damage, though invisible, starts almost immediately upon exposure to the sun. Visible damage—a tan or a burn—doesn't show up until it's too late.
8 Minutes: Fair skins redden
How serious can the damage be?
When the sun's UV–rays penetrate skin they can attack DNA, the genetic material inside each cell that controls everything the cell does.
12 Minutes: Medium skins redden
How can I protect against UVA rays?
Look for sunscreens that offer stabilized UVA protection. Be sure they contain UVA filters such as titanium dioxide, zinc oxide or avobenzone (Parsol 1789). Explore UV–protective products recommended by the Skin Cancer Foundation including window film, sunglasses, clothing and laundry additives.
25 Minutes: Dark skins redden
Will a tan protect skin from further damage?
The idea that a tan offers adequate UV–protection is a dangerous myth. A tan provides only minimal protection—the equivalent of SPF 2 or 3. Dermatologists advise daily application of SPF 15 and up.
Should I go to a tanning salon instead?
We'd say no. Most tanning beds or lamps use UVA rays—two to three times as much as in sunlight—because they are less likely to cause a burn. Now, scientists recognize that UVA rays are worse than a sunburn in terms of premature aging. Recent data link tanning beds to far more serious skin damage.
Any way to get a safe tan?
Clinically speaking, no. The only “safe” tan is a non–sun tan. Fortunately, fast and easy self–tanning formulas are readily available. Caution: In the sun, always wear sunscreen with your self–tan.
Doesn't my skin need sunlight to make vitamin D?
Yes, your skin creates vitamin D from sunlight—specifically UVB. Fortunately, incidental exposure may be all you need. But if you're older, dark–skinned, or live in northern latitudes, you may not get enough sun year–round. Talk to your doctor about sun–free ways to get your daily dose: foods naturally rich in or fortified with vitamin D (fish, dairy) and supplements.
UV vs. DNA—What it does to skin
Takes its toll on many types of skin cells, structures and systems:
Skin cell, structure or system/effects of uv-exposure / resulting damage melanocytes:
||Lose their ability to produce melanin (tanning pigment) evenly. / Age spots and blotchiness.
||Dilate from heat, UV-rays. / Visibly swollen or broken capillaries.
||Less protection against moisture loss. / Dehydration and dryness. Lines and wrinkles look deeper.
||Fibers fray, repair mechanisms break down. / Sagging. Wrinkling.
|Immune system cells:
||Suppressed ability to “clean up” damaged cells. / Damaged cells replicate, harm healthy cells.
