I had such a positive experience at SISU Castleknock, and I have to say Georgia is absolutely fantastic at what she does. From the moment I arrived, she made me feel completely comfortable and at ease, which really helped as I was a bit nervous beforehand. She took the time to go through everything in detail, explaining the treatment, what to expect, and answering all of my questions without ever making me feel rushed.
What really stood out to me was how honest and knowledgeable she is—she gave genuine advice and focused on achieving a natural result rather than overdoing anything. You can tell she really cares about her clients and takes pride in her work. During the treatment itself, she was so gentle and reassuring, constantly checking in to make sure I was okay.
I’m absolutely delighted with the results—they look so natural and exactly what I was hoping for. I’ve already had so many compliments, and I feel so much more confident. The clinic itself is spotless, modern, and very welcoming, which just adds to the whole experience.
I wouldn’t hesitate to recommend Georgia to anyone considering treatment. She’s professional, skilled, and genuinely lovely to deal with. I’ll definitely be returning to her again ⭐️⭐️⭐️⭐️⭐️
I had a great experience at Sisu Clinic. It was my first time getting lip filler and Botox, and Dr. Cole was professional and reassuring. The treatment was less painful than expected, and I’m very happy with the natural-looking results. I’ll be back for my follow-up and would definitely recommend Sisu Clinic.
I visited SISU Clinic ahead of my wedding and had such a fantastic experience. I chose them because they’re doctor-led, and it really shows in the quality of care.
I had a consultation with Dr. Cole in the Castleknock clinic, as I was interested in Sculptra. He created a personalised treatment plan with a clear timeline and, most importantly, was incredibly honest—he actually advised against treatments I didn’t need, which I really respected.
The whole experience was professional and welcoming. Yolanda at reception was lovely and made everything seamless.
The treatment itself was very comfortable—Dr. Cole was gentle, precise, and clearly very skilled. Just a week and a half later, I already love the results. My face looks refreshed and natural, exactly what I wanted.
I’ll definitely be back—highly recommend!
The girls in Sisu are amazing ♥️ so welcoming and make you feel so comfortable. Georgia was so professional and provided an amazing treatment & Yolanda was so helpful on reception providing information on products and explaining the special offers. Would recommend to anyone to pop into the clinic in castleknock
5 stars for the girls in Sisu Castleknock! They are so friendly and informative about all the products and services. So much choice but they take the time to talk about what you need and make the journey easier. Great range of Image products also at great prices so definitely worth visiting! Thanks to Sarah Yolande and Vik
It was my first time having an aesthetic treatment, so I was quite nervous, but Dr. Georgia Collins was very patient and explained everything clearly, which made me feel comfortable. I’m very happy with the results, my lips look very natural, exactly how I wanted. I would definitely recommend the clinic.
Lisa Marie and Dr. Cole were so lovely! Dr. Coke answered all my questions and gave me some excellent advice on how to get the most out of my botox treatment. Lisa Marie was also a huge help when I had to reschedule last minute.
I had the best Botox treatment I’ve ever experienced with Dr. Cole. In the past, I had found it difficult to achieve the right dose and placement for my needs, which made me hesitant about continuing treatments. After discussing my previous experiences, Dr. Cole understood exactly what was needed and achieved excellent results from the very first appointment, with no review required. My second treatment was just as successful. I am extremely happy with the outcome and the consistency of the results.
