I always liked the very clean & minimal look of Skinklinic, a (closed) medical spa & skin clinic in NYC.
I never got a chance to make it in to Skinklinic but I always liked the very clean lines and design.
From what I remember, Skinklinic overreached and expaneded to a couple of locations that they couldn't support and ended up closing downw. (Sleek Medspas have their domain now and I'm guessing that they purchased that in order to get some trafficl. I don't think that Sleek medspas have anything to do with Skinklinic. If anyone knows, please leave a comment.)
The startup and build out for this kind of skin clinic are out of the reach for most locations and physcians but it's always both interesting and informative to see where others have gone.
