Topics | Allergies | Can symptoms of skin allergies cause permanent skin damage? Usually, symptoms of skin allergies-like hives, rashes, redness, and itchiness-last only a few days. If blisters form, they may last for a little longer, but even those usually disappear after a few weeks. In certain cases, especially with particular skin conditions or recurring severe allergic reactions, the skin that's affected may be permanently hardened or thickened. Scratching or rubbing the skin can also cause permanent damage, either by thickening the skin or by scarring the skin after cutting it open.
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.
