Yes, It worked for me. It was a little challenging since it was on my face and I kept it covered with a bandaid and my skin broke out because of the adhesive in the bandaid. I applied a small dab only on the angioma each night for about 4 days and a sore developed (plus my skin irritation where the bandaid was) but after about a week the sore healed over with a scab and after a couple of days the scab came off and the skin healed over absent the angioma.
Luckily, it was on my forehead and I could cover it with my bangs.
I've got several more angiomas to do but they are on difficult areas of my body and the problem is my allergic reaction to the bandaid adhesives.
