Re: can benzoyl perioxide permanently damage skin??? Yes, BP can cause a dermatitis (permanent skin damage). I had problems with BP, I used it for the spots, but when I applied it my skin went red (it like burned...)on the spots I had applied the BP. I personally don't like BP at all.
A tan is visible proof that your skin has been damaged by UV rays. Tanning is your skin's response to overexposure to UV rays. Sunburn is also caused by too many UV rays: your skin turns red and may become hot and painful or even swell and blister. Overexposure to UV rays also causes premature aging effects, like: 1  skin wrinkling and hardening (leathery skin) 2  blotchiness. 3  loss of elasticity. 4  dark patches (age spots or liver spots) 5  precancerous skin changes (called actinic keratoses) Skin damage caused by the sun is cumulative. This means that long-term, daily exposure to sunlight adds up. UV exposure causes damage in the DNA of your skin cells. Damaged cells die or repair themselves. If, however, the damage is too severe to be repaired, you can get skin cancer.
