The general cost, per session, is about 300-350, but many places offer sales. You'll need a package of between 3 and 5. I must say, I thought, at the beginning, 3 were sufficent. The 4th and 5th treatments were very strong and I thought, at the time, that I could have lived without them, but I also believe that's where I saw the biggest boost in the underlying collagen levels. I really looked pretty fantastic after 5 treatments. I get 1 booster, every year, to keep the wonderful results. You might want to check out a new treatment, called Active FX. It's more expensive, but you only need one treatment. It repairs sun damage, rebuilds collagen, and provides some skin tightening as well (about 30%, I've read). I think it will be what I try next, instead of my yearly Photofacial. I look years younger then I did before my Photofacials. It was certainly worth the money to me.
