In search of "safe" tanning, many people resort to tanning booths or tanning beds. While tanning companies will tell you their light machines produce only UVA radiation, the nonburning type, UVA rays are far from safe. In fact, UVA rays penetrate the skin even deeper than UVB rays do. Over time, exposure to UVA rays can make skin dry and wrinkled and increase the risk of skin cancer.
As you can see, protecting your skin from sunburn isn't just to avoid discomfort. Too much sun exposure can contribute to dry, wrinkly skin, brown spots, and, worst of all, skin cancer. Unfortunately, there are no home remedies to cure the damage from sunburn, so always be careful when in the sun.
