I recently visited SISU Clinic in Flatiron for Botox (men’s treatment), and the experience was honestly exceptional from start to finish. The staff were extremely professional and welcoming as soon as I arrived. Samantha, who performed the treatment, was absolutely amazing — she has a fantastic personality, made me feel totally at ease, and clearly knew exactly what she was doing. Her attention to detail and friendly, relaxed approach made the whole experience super comfortable (and actually fun, which isn’t something you usually say about injectables). I can already tell the results look natural and subtle — exactly what I wanted. If you’re looking for somewhere that’s professional but approachable, SISU Flatiron and Samantha are top-notch. Highly recommend!

I had such a lovely experience at SiSu. Lindsay at the front desk was so friendly and welcoming when I arrived, really helpful and easy to chat to! Samantha did my lip filler and I honestly couldn’t be happier. She really listened to what I wanted and didn’t rush anything. She explained everything clearly and made sure I was comfortable the whole time. I wanted something subtle and natural, and she absolutely nailed it. My lips still feel like me, just a little more balanced and defined. You can tell she really cares about getting it right. I’d 100% recommend Samantha and the team at SiSu.

LOVE LOVE LOVE! I was greeted by Leen who is one of the sweetest people! Botox can be a scary experience but I immediately felt at ease. THEN I met Samantha- she is such a doll, so professional and sweet. She knows what she’s doing. I did my forehead, crows feet and a gummy smile. She acknowledged my insecurities and came up with a solid treatment plan. Only a few days out post treatment but am LOVING the results so far. I feel fabulous and my confidence is at an all time high! It can be difficult finding a good injector in nyc because there are SO MANY. I highly recommend Sisu and I will definitely be back!

Had an amazing experience! Emily is my new go to girl love this location super clean and friendly staff! My filler was done very carefully and she pays very close attention to what you’re asking for to make sure your needs are met and you get what you asked for! Minimal bruising and swelling, painless experience. I got a lip flip and lip filler.

I thoroughly enjoyed my experience! The moment I walked in immediately I was greeted by Lindsay! I noticed how clean bright, and welcoming it was! I arrived early; and fragrance inside smelled so amazing I was glad I had time to take in the scent. Once I entered the room for my consultation with Emily( the Dr. ) she gave me and opportunity to explain my goals, and to ask all the questions I had ( Which was a lot ) she was very knowledgeable and informative. Emily gave me recommendations on which procedures to choose that would be best. I only intended to just have a consultation, the way she made me at ease while educating me I went ahead and got the procedures done. I am very pleased so far!! I recommend seeing Emily if you would like to enhance your appearance! ✨🪄✨ Like this post and be sure to Mention “ Rashaad G. “ Sent you so you can receive a discount
