What You Need to Know Effects of Sun Sunburn. Overexposure to the sun can happen in just a few hours. A bad reaction includes tenderness, pain, swelling, and blistering, and may include fever, chills, and nausea. While there is no cure for sunburn, wet compresses, cool tub baths, and soothing lotions may help. If you have a bad burn, see your dermatologist.
Some people think that a tan means good health and looks.
Dermatologists know that a tan does not prevent sun damage, it is sun damage. Tanning occurs when the UV rays penetrate the skin and injure the pigment cells. The effects are cumulative, and with every burn, the skin becomes more damaged. People who work or lay in the sun without sufficient protection get sagging cheeks and deep wrinkles that may make them look much older. The sun can also cause unsightly red, yellow, gray, or brown spots and scaly growths that may develop into skin cancer.
