Botox on Forehead and Eyebrows

Dr. Hammerman is excellent! I highly recommend her for Botox treatments. Her injections were spot on, so that my results were smooth and even from the beginning - no touch ups needed!

This was my first time trying Botox! Dr. Hammerman walked me through the entire procedure so that I was at ease. My results were better than expected and I can't wait to go back in a few months for another treatment!

28 Years Old - Juvaderm and Botox - New York, NY

I could not be happier with the results of the botox (forehead) and juvaderm (lip) injections I visited Dr. Hammerman for. She is not only an incredibly talented doctor, but also extremely friendly and personable. We discussed my goals and the results were exactly what I hoped for. So natural and beautiful! I highly recommend a visit to Dr. Hammerman if you are considering these procedures.

Great Experience for First Time Lip Filler - Forest Hills, NY

I recently visited Dr. Karen Hammerman in her Forest Hills location for a lip filler consultation. I never had any fillers prior to my visit with Dr. Hammerman, so I had many questions. She explained in great detail about the procedure and product, and I never felt rushed during the appointment. I felt very comfortable in my decision to go through with getting a lip filler with Dr. Hammerman....

Struggling with Melasma on my Forehead for over Three Years! - Forest Hills, NY

I highly recommend Dr. Hammerman for not only Fraxel Laser, but for injectables and dermatology services. Just after my treatment, my Melasma is gone! I also had Dr. Hammerman inject juvederm in my cheeks and everything looks flawless! She is incredibly professional and I'm very excited to have a dermatologist for laser, injectables and dermatology services. Very exciting! Dr. Hammerman is always available for questions and concerns. She even called to check up on me!
