Fever blister question? Would rubbing alcohol reduce appearance?

I had what looked like a fever blister , a “type” of cold sore that looked more like a blister on my upper lip towards the middle. I put alcohol on it and it went down then went away. Does alcohol work like that on fever blisters or do they tend to scab over once you do that? Or do you think it was even a cold sore/fever blister? Someone I was newly dating kissed me a week or 2 prior before it appeared.
