Medical Aesthetics, New York

Dr. Leslie Gerstman doesn't just fight aging and other skincare woes with cutting-edge nonsurgical treatments; she also teaches patients how they can look fresh-faced by de-stressing, improving their diets, and stopping all their clocks. For more than a decade, Dr. Gerstman has been using this holistic approach to create personalized regimens tailored to each patient's aesthetic goals and skin type.

For instance, she might look at two patients with acne and determine one needs an Isolaz broadband light treatment to stop excess oil production and that another needs a gentle fruit-acid peel or topical retinoid to unclog their pores. No matter what treatment the client needs—acne remedy, Botox injection, Ultherapy eye lift—Dr. Gerstman first performs a one-on-one consultation and explains how she'll achieve noticeable results without too many alterations.
