How Makeup Can Affect Your Health

Cold sores are painful red sores that form near and around the mouth. In some cases, a clear liquid will leak from the blisters before scabbing over. Cold sores are caused by the HSV-1 virus, with most people becoming infected with the virus before the age of 10. Recurring blisters are then triggered throughout life by stress, colds, fever or trauma to the lips. Cold sores can also be caused by prolonged exposure to sunlight, kissing — and even sharing cosmetics like lipstick, lipgloss or chapstick with others. There is no known cure for cold sores, but most clear up on their own in a few days. If you think you may have a cold sore, talk to your doctor.
