I had four IPL treatments over the course of 8 months and my skin looks great.
I am 41, very fair with red undertones, had some sundamage and broken capilaries, and fine wrinkles under my eyes. IPL improved everything dramatically except for the fine wrinkles. I look 10 years younger.
I have a very experienced, dedicated laser nurse who is up on all the technology and works in a well-known cosmetic surgeon's office.
The worst thing I can say about it is it hurts (I didn't ever use numbing cream) and my face was swolen for 24 hours afterwards. It seems like purpura and burns can happen if the energy level is too high or you have darkish skin- I'd really check around for someone who knows what their doing before trying IPL.
