I moved out of NYC and one of the things I miss the most is Defining Beauty. Bernadine’s work was always subtle and natural looking, but at the same time it made all the difference! I look forward to when I’m in NYC so I can pay her a visit!

I am often complimented on my skin.  I must attribute it to “Defining Beauty”.  They do an amazing job. I always feel like a new person!
Thank you “ Defining Beauty”

This was my first time to Bernadette and I am new to laser work. She was kind, caring, and professional. I most definitely see  an improvement in my skin tone, and I plan to continue to see Bernadette at Defining Beauty. I highly recommend her.

An amazing experience at Defining Beauty!  Bernidine, the owner is fantastic and so helpful as well as a receptionist Michelle!  Billie the Nurse Practitioner was phenomenal. This was my first time having Botox.!  I would highly recommend coming to Defining Beauty!

I've had great success with all my treatments at Defining Beauty. I've had an old tattoo removed as well as lasers to improve my skin. Next up I plan on getting my eyebrows microbladed.  I also love the skincare line.

I saw Raquel for laser hair removal and couldn’t be happier. I’d recommend Defining Beauty any time

I have been coming to Defining Beauty for several years. The RN and the doctor that does my botox are both very nice. I also have had facials and laser treatments to tighten my skin. I give this place A plus. What I like best that unlike other places, the staff here take their time and explain everything and you never feel rushed.

I love Bernie - such a kind person. I've seen many people over the years for my eyebrows and she's the best. I also get laser skin tightening and microneedling, too.

So happy with the results of my treatments.  Bernadine is gifted and makes you feel so comfortable.
