Cold sores — also called fever blisters — are a common viral infection. They are tiny, fluid-filled blisters on and around your lips. These blisters are often grouped together in patches. After the blisters break, a scab forms that can last several days. Cold sores usually heal in two to three weeks without leaving a scar. Cold sores spread from person to person by close contact, such as kissing. They're usually caused by herpes simplex virus type 1 (HSV-1), and less commonly herpes simplex virus type 2 (HSV-2). Both of these viruses can affect your mouth or genitals and can be spread by oral sex. Cold sores are contagious even if you don't see the sores. There's no cure for cold sores, but treatment can help manage outbreaks. Prescription antiviral pills or creams can help sores heal more quickly. And they may reduce the frequency, length and severity of future outbreaks. Products & Services
