Same thing here. My daughter's is on her left eyebrow and it gets puffy from time to time.....In fact she was completely weaned off of propanolol for about a week and her H got a bit puffy and we were worried it was growing again so the doctor had us put her back on 1 dose a day unless we want to do 2. It will depend on how it looks but I think the puffiness is normal. I am like you I'm not sure if it's the skin stretching or re growth. I watched my daughters for a couple of days and I thought it was getting larger but wondered if it was just extra skin. Finally after almost a week I called her doctor and he said to put her back on one or two doses -whatever I felt necessary. She was down to one dose before we weaned her completely off so she seemed fine on one dose so I just put her back on that. But when she does her little 'face krinkle' I notice it more. Not sure. Just wanted to let you know we are seeing the same thing here.
