At Phoenix Medical Spa, a nurse, medical aesthetician, dental hygienist, and duo of doctors help beautify clients with high-tech treatments. A doctor or nurse might soften wrinkles with dermal fillers, while the dental hygienist whitens teeth. The medical aesthetician performs everything from CoolSculpting body-contouring procedures, which freeze unwanted fat cells, to diamond-tip microdermabrasion treatments that gently resurface the face to reveal younger-looking skin. Registered nurses perform the cosmetic injectables with over 10 years of experience injecting.
