Sue - I can't remember what mine was called exactly, but I remember I had extractions, which was very important. It's just like what it sounds like, but it's good for people with acne because it provides a safer and better way to "pop" pimples without the risk of scarring and spreading the infection. It also involved a mist and 2 different masks. One that felt like it was exfoliating and then a soothing one at the end that relieved any inflammation from the extractions or otherwise. I found a link that describes different types of facials. The one I got sounds a lot like the acne facials on the page.
When I went in for the first time she looked at my face and kind of decided from there what treatment I should get. So, it may depend on how severe your daughter has it and things like that. But, hopefully it gives you an idea on what to look for
I would say extractions were the biggest help for me. I had such clogged pores (even though I cleaned my face all the time) that it helped to have a professional clean them out with products that healed my skin rather than irritate it even more like so many store products tend to do (ie Oxy pads!!).
I think spa technicians can be certified in holistic care too, so maybe ask for the persons credentials too
I will try and find some of the product names I went home with when I get home from the doctor's. They're going to be more expensive, of course than your typical product. But probably no more so than going to the dermatologist would and I would say if they help then you won't have to use as mjuch in the long run
Let me know what you find out!
