When your skin is bright red and sensitive from a sunburn, you may not think your body is doing you a favor. However, new research from scientists at the University of California in San Diego suggests that sunburns are an immune system reaction that helps to clear the body of genetically damaged cells.
Sunburns are a symptom of skin damage, which is a precursor to scarring, premature wrinkles, and even skin cancer. However, exposure to UV light is part of treatment for many conditions and diseases, including psoriasis. When UV rays interact with skin cells, they damage the cells’ RNA. Undamaged cells in the area become inflamed, red, and painful in order to flush the cells out.
The research is important because ultraviolet therapy is frequently used as treatment for various disorders like psoriasis and vitiligo. Knowing more about sunburns could help scientists find a way to trigger this healing process without putting patients at risk for skin damage.
Until then, the healthiest choice is to stay out of the sun and wear sunscreen when you go outside. For more information on keeping your skin healthy, contact Zimmet Vein & Dermatology today.
