Well, do yours hurt? Is it tender at all? Is it in both corners of your mouth?
Herpes sores wouldn't typically appear in both corners at the same time, and would at least be tender. The blisters will scab over, forming a scab, and then heal.
Fordyce spots will just be there.
There are other things that it could be - an allergic reaction, angular chelitis - though it doesn't look a lot like that, irritation. If it's sore or tender at all, let your doctor take a look.
