This Sephora location is my favorite. It has a convient location right next to the food court in the Scottsdale Fashion mall. Also, it has an entrance from outside so you don't have to make your way around that huge mall to find it.
The employees are extremely helpful. They also have many professional makeup artist available to help you. I use "Makeup Forever" products and I had a very nice young woman color match me with no problem. It's always good to have employees who at least appear to be happy and know what they're talking about. Anyways, love this Sephora! Will recommend this location over any one In the East valley.
