I think I just discovered cold sore treatment with IPL.

I had a cold sore, a really small one on my lower lips but it still tingly and annoying. This morning I got IPL treatment and the laser light go over my upper lips area. Right after the IPL I noticed my lower lips had a red spot. It was my cold sore dried out and red from the dry blood. Now, it's about 2:45 pm and my cold sore and tingleness is totally gone. My 2nd day of cold sore out break and it usually last for 7or 10 days.WOW! Did I just discovered the fastest way to get rid off cold sore?
