Ahemmmmmmm *sneaks in* yes I have had it...ummm a fair bit... LOL you need to keep it up to really get the benefits. I have it once a year now, but earlier on I had it every 4 months then made the gaps longer between. Its great as a preventative for deep lines...thats my argument and I am sticking to it!
If you want any more specific info PM me ...*sneaks out*
