Cold sores are a cluster of blisters that first appear clear then become cloudy. First infection may be inside the mouth, but cold sores generally appear outside the mouth on the lips. Canker sores are gray or white sores surrounded by a red inflamed area.old sores typically result from a viral infection called herpes simplex virus (HSV). Cold sore blisters can occur on many different parts of the body but are most common on or around the lips, cheeks, or nose and also (on rare occasions) in the eye.
Canker Sores Aren't the Same. Cold sores usually appear on the lip; canker sores affect the inside of the mouth. Canker sores aren't caused by the herpes virus and aren't contagious. No one knows what causes them. Cold sores generally start with red, irritated skin. Blisters form, break open, and crust over before healing.
