What really happens to your skin when you skip the sunscreen

Too much sun makes the problem a lot worse by breaking down the collagen beneath the skin. The blood vessels near the surface of the skin are also damaged. When the skin gets hot the body tried to cool down by dilating and bringing superficial veins to the surface, according to the NJ Vein and Vascular Center. Sun exposure may also cause spider veins, especially on the noses or cheeks.
