PATIENT REVIEWS

UNION SQUARE

VICTORIA

“I suffered from pretty moderate to severe melasma for the past 5-6 years. With no exaggeration, Dr. Anne Chapas has changed my life. My melasma has nearly disappeared! It started to improve about a week after starting her 3-pronged treatment. I look younger, my skin is glowing and healthy, and my self-confidence has soared.”

JENNIFER

"I recently saw Dr. Chang for laser treatment of my brown spots and for Botox and loved my results. Dr. Chang is an expert in Asian skin and tailored my treatments to get the best results as I had complications from previous dermatologists light/uneven spots, droopy eyes, bad reactions. I could tell she truly cares about her patients and I can't wait to go back to see her!”

“The new uptown location is equally as STUNNING as the downtown location. The views make you feel like you’re at The Plaza, except you’re getting fillers instead of tea!”

"Dr. Chwalek has a very natural, relaxed manner that makes me feel I am speaking with a friend. She is very honest, trustworthy, non judgmental and receptive to any new information I might have about procedures that I find interesting.”

JUDITH

Everyone here is a total perfectionist! I’ve been a patient of both Dr. Chapas & Dr. McGregor for many years. I have olive skin & I’m delighted my treatments are tailored to optimize outcomes for my particular skin tone. I deeply appreciate their attention to detail & their flexibility in being able to treat patients with all skin types. I am over 50 & am often mistaken for a woman in her 30’s - I owe it all to Dr Chapas & Dr. McGregor! They are loyal partners in my fight against aging & pursuit of healthy skin. I recommend them both with all my heart.

NOEMI

“If you're looking for the BEST dermatologist, look no further. Dr. MacGregor is absolutely amazing! As a physician myself, I'm extremely discerning about who I go to for my own medical care. Dr. MacGregor's professionalism and knowledge is simply unparalleled! I've been a patient for about 10 years now, and thanks to her, I look and feel much younger than my actual age. People comment all the time on how great my skin looks - I can't thank her enough!”

VIRTUAL

CHRISTY

I had a virtual consultation, which I really appreciated given everything with COVID. Dr. Chang had reviewed my photos in advance, so she was very prepared and ready to talk about my areas of concern and already had a treatment plan prepared and ready to discuss with me. She was very thorough. I also appreciated that in no way did I feel like I was being "upsold" on additional treatments that may or may not be necessary. Dr. Chang was very honest and clear about what would work best with my areas of concern.

JAWNA

I base every other medical appointment experience based on the bar that Dr. Chapas has set. Not only is she a leading authority in her field, she’s an incredibly kind & personable doctor. I have yet to have any doctor's visit be as smooth and pleasant as when I visit Dr. Chapas & her team of amazing nurses & administrative staff. I just had a Sofwave laser/tightening treatment. It was painless. So far, I’m delighted with the results! I can’t wait to return in 3 months.

RONALD

Dr. Robyn Gmyrek is the best doctor I have ever had. Her professional nature is only matched by the care and true love you feel being one of her patients. It is always best to see the doctor with the greatest skills, but when that doctor is matched with the greatest patient care and kindness, you are truly lucky to be in her care! Thank you!

“Just had the best facial of my life from Rhea. If you need extractions and an expert, then see the best - she knows skin like no other! La Suite has the best product to keep you glowing. All of the aestheticians are lovely and highly skilled. The entire place is spotless and the machines/technology are top of the line. Treat yourself!”
