10 Cold Sores Symptoms
Pink Skin
The cluster of blisters should heal on their own in one to three weeks. Once the blisters are gone, the skin underneath will have a pink appearance. This discoloration slowly fades on its own.
Most cold sores won't leave a scar. However, individuals that pick at the blisters or itch them excessively might experience some minor scarring. Avoid activities that aggravate the blisters, such as aggressively washing or rubbing against a collar or similar clothing type, to prevent permanent damage.
