A tan, whether you get it on the beach, in a tanning bed, or through incidental exposure, is caused by harmful UV radiation. If you have a tan, you’ve damaged your skin cells, there is no “healthy tan”.
The cumulative damage caused by UV radiation can lead to premature aging (wrinkles, lax skin, and brown spots), as well as skin cancer. Indoor tanners are 74 percent more likely to develop melanoma than those who have never used a tanning bed.
If you rely on sun exposure to increase your vitamin D levels, consider taking a vitamin D supplement instead. You will achieve the same results without the risk of skin cancer and premature aging.
If you are going on vacation or want a change of pace for summer, consider a spray tan. Many salons offer custom blended solutions applied by skilled technicians that mimic the appearance of a natural tan without the damage to the skin cells.
Make sure you are wearing an SPF with a high concentration of zinc oxide for the best protection on a daily basis.
