    I highly recommend Dr. Zand for fillers and Botox. In addition to her charming personality, she is…read morededicated to quality care. She is warm and friendly and at the same time highly professional. Dr. Zand listens carefully to her patients about their concerns and offers excellent guidance about treatments to address them. She is highly knowledgeable, experienced and gentle. Her office and staff are welcoming, and Dr. Zand treats them with the same consideration and respect she shows her patients.

    Why when I go there for a chemical peel am I greeted by a dog barking a lunging towards me? Not…read moreeven like a cute poodle or something but a fierce albeit small Tasmanian Devil like dog. The esthetician proceeds to pick the dog up with her bare hands that would soon be touching my face and go into a room with the dog for 5 minutes. Then comes out and ask if I can wait while she walks the dog. As I am leaving (because who would stay for an appointment after that) the dog comes out barking and lunges at me again. I had a prescription pickup that I confirmed over phone 4 separate times was hydroquinone with retin a and they give me hydroquinone with kojic acid. Ask estetician and she goes "I don't know that's what the left" That what she said for real. At least she went to "wash her hands" for I kidd you not,10 seconds, before looking for the prescription.For getting a prescription no big deal but what if that would have been the hand wash before the procedure? Omg.
