Hi there, I was wondering if you could tell me more about how home IPL devices work in comparison to in salon ones? I have a smooth skin IPL which for about 8 months I used on my upper lip over a year ago. I'm 33 and have noticed very faint vertical upper lip lines, I think I am too young to have to the start of these and was wondering are in home IPL devices capable of causing damage like this? My understanding was that they were far less powerful but now I am unsure and concerned. Many thanks
