Dr. Harkavy and the team at Form & Function Aesthetics and Wellness are incredible! I just received my Neogen Plasma treatment and I am already impressed with the results! My skin is brighter and tighter, and I can't wait to see my results in 30 more days! I highly recommend the team at Form and Function for any of your aesthetic needs!
Dr. H and her team are excellent! I had the Neogen treatment and I cannot believe the before and after in only one month! My face is tightened and I don't look tired anymore. Dr. H is compassionate and listens to your concerns with what you would like to treat.
Madeline Ortiz is amazing! She talked me through everything and made me feel very comfortable! My lips came out so good.
PA Madeline Ortiz performed my Xeomin and Radiesse Injections (Botox and filler) and I loved it! She explained the procedure and gave after care instructions. She has a very soft touch, making it a painless experience. I highly recommend her!
