Rejuvenation Clinic, New York

As a medical doctor and integrative medicine practitioner who specializes in treating pain and aesthetics, Dr. Jignyasa Desai understands the need for treatments that work and work fast. It's with this idea in mind that the doctor has outfitted each of her three New York-based clinics with advanced beauty and health equipment.

Computer diagnostics and pain management programs help Dr. Desai and Dr. Elena Agilina locate and treat the root of health problems. Dr. Desai and her team also stave off signs of aging with both simple aesthetic treatments such as Botox injections as well as more involved services. These latter include infusing oxygen into the epidermis via a gentle-pressure machine and performing Ultherapy, which uses painless ultrasound technology to lift aging skin, a procedure highlighted by Barbara Walters on 20/20.
