I have tried quite a few treatments with all members of the staff...they are all wonderful. I would not hesitate to have any of my services performed by any of them. I think the prices are on the low side for Newbury Street, but the quality of service far exceeds anything I've had. The staff is pleasant and knows their collective stuff. Also, I feel very comfortable in the spa....a new place can be intimidating, but not Kosmetika. HIGHLY RECCOMMENDED!!!!
Kosmetika is a great spa. I have been to Le Pli and some of the other top-rated spas, but I prefer Kosmetika. I have been for individual treatments and twice for the full day experience. It is a smaller spa than some others, but they have most if not all of the services the other spas offer. And, they're slightly cheaper than Le Pli. I recommend them with no reservations! Enjoy!
