How contagious are cold sores?
Your body is feeling run down and you start to feel a cold sore emerging. You don’t think much of it, because how contagious can they really be? An Ohio State dermatologist explains.
Ultraviolet (UV) rays are an invisible form of radiation. They can pass through your skin and damage your skin cells. Sunburns are a sign of skin damage. Suntans aren't healthy, either. They appear after the sun's rays have already killed some cells and damaged others. UV rays can cause skin damage during any season or at any temperature. They can also cause eye problems, wrinkles, skin spots and skin cancer.
To protect yourself:
Check your skin regularly for changes in the size, shape, color or feel of birthmarks, moles and spots. Such changes are a sign of skin cancer.
