5 out of 5 stars IPL

AMAZING; Dermatologist!!! - Commack, NY

I rarely write reviews but I just felt I needed to let people know what Dr. Papantoniou did for me because it was something I was so unhappy with for so long. Dr. P COMPLETELY got rid of my sunspots using her laser technology! Someone literally compliments me on my complexion almost everyday and I truly owe it all to her. Before Dr. P I tried sooooo many creams, lotions you name it, if I saw...

Incredible Doctor! Commack, NY

It's doctors like Dr. Papantoniou who remind you that your doctor cares about you as a patient. During the time she spent with me it was obvious that she cares about her patients and their treatments. She takes her time during every procedure and does everything she can do to make you comfortable in her office as well as help you find the best treatment possible with or without insurance. I would recommend her to anyone who asks for any procedure. I will definitely be returning to her for all my dermatological needs!

28 Years Old, Deep Nasolabial Folds - Commack, NY

Dr. P is extremely personable and knowledgeable. I was nervous and hesitant going into the procedure, but her friendly disposition put me at ease. She was eager to hear what my wishes are and came up with a couple of treatment options for me to choose from. All my questions about the product, the procedure and aftercare were answered. The actual procedure was virtually painless and I couldn't be happier with the results! She has a great eye and knew just what to do to achieve the look I was going for.

5 out of 5 stars Botox

Excellent doctor

This doctor was everything I need and want in a dermatologist. I got Botox for the crease in between my eyebrows, and I got filler for my nasolabial folds. From the second she entered the room, I felt safe and comfortable with her. She is sweet, warm and comforting, and she explains things very clearly. She also never tried to sell me anything and even suggested I try one syringe for filler...
