Positive experience with Polynucleotides

I had a great experience with my polynucleotide treatment at Sisu Clinic. I booked a course of three sessions and received friendly, professional service throughout, starting from the initial consultation where there was absolutely no pressure to go ahead with the procedure.

Both Dr Nila and Dr Imana were professional, knowledgeable, and made me feel comfortable during the treatments. I’m really pleased with the results so far — I’ve noticed a visible reduction in my under-eye bags and shadows, and my eye area looks much fresher overall. I’d definitely recommend the clinic and team.

5 star experience with Dr Nila and Noor

Had such a lovely experience at Sisu Clinic today for my Botox and lip flip treatment. Dr Nila was so friendly, gentle and made me feel completely comfortable throughout the whole appointment. The treatment was quick, smooth and I was in and out in no time.

Also a special mention to Noor at reception who was so welcoming and friendly from the moment I walked in. Such a beautiful clinic with amazing staff. Highly recommend.

Highly Recommend Dr. Nila and the Sisu Team

I had such a wonderful experience at Sisu, and I want to especially thank Dr. Nila and Mariam at reception.
Dr. Nila is not only an exceptional professional, but also a genuinely warm and kind person who made me feel comfortable and confident from the very beginning. She took the time to listen to all my concerns, answered every question with patience and expertise, and completely removed any doubts I had. Her professionalism, attention to detail, and honest advice made me feel I was in the best hands. The results are absolutely amazing.I truly feel like she has taken at least 5 years off my face, and I couldn’t be happier. I would wholeheartedly recommend Dr. Nila to anyone considering treatment.
Mariam at reception was equally wonderful. She was always welcoming, friendly, and incredibly helpful. She went above and beyond to help me find the most suitable solution for my needs, making the whole experience smooth and stress-free.
Thank you both for your care, professionalism, and kindness. You made this experience truly special.

Avoid if you value aftercare. Substandard results & zero accountability

I have been a regular recipient of anti-wrinkle treatments for over five years, but my experience at Sisu Clinic has been so distressing that it has put me off treatments entirely.
Following an initial treatment that left me with significant facial asymmetry, I attended a corrective appointment which only increased my distress, I was offered no resolution except for "the other brow will drop to match" - it did not, and 3 months later I am still asymmetrical.

Despite this, Sisu’s "Medical Directors" have now hidden behind clinical protocols to refuse any fair resolution, effectively telling me to just "wait it out" while living with a botched result.

The Principle: It’s not about the money; it’s about the appalling lack of care following a medical treatment gone wrong. I understand this is a risk of the treatment, but the total lack of care or accountability is what is most shocking to me.

Communication is non-existent, I had to follow up on every single email, often waiting up to two weeks for a response while dealing with a physical complication.

The Resolution: They offered a 10% discount on future services. Why would I spend more money at a clinic that has already failed me physically and ignored me professionally?

If you are looking for a clinic that takes responsibility when things go wrong, look elsewhere. Sisu is happy to take your money, but they will leave you high and dry if you suffer a complication at the hands of their team.

I’ve had a few appointments now and I still recommend Sisu. Everyone is incredibly kind and caring, they listen to you and make sure any questions are answered before you go ahead with anything. Would happily come back.

Central London service is terrible

I walked into the central London clinic to ask about available appointments. The staff were all chatting in the doorway, was told there were no spaces even with the website should appointment times free. I have used Sisu before but the service has really gone downhill it seems, tried to reach out to customer service to give feedback and couldn’t get through on their website either! Ended up going to Therapie which is always professional but slightly more!!

Friendly service and expert care from start to finish

Had a really great experience from start to finish. Yanisha on reception greeted me warmly as soon as I arrived and made the whole check in process smooth and easy. She also helped me get booked in for my follow up appointment, answered all my questions and even offered me water while I waited which was a really nice touch.
Dr Pedram was excellent. Extremely knowledgeable, professional and took the time to give honest advice. I felt completely comfortable and confident in everything he recommended.
Highly recommend Dr Pedram for any guys considering getting something done. One very happy client here!

Amazing clinic

I've been coming to Sisu to see Dr Nila for almost a year, and I am so delighted with the service and expertise offered at the clinic. I've been getting preventative botox, and recently started masseter botox for teeth grinding with Dr Sonia. Sisu has made a huge difference to my confidence and also my health! I have also found Dr Sonia really cares about the aesthetic I prefer, for me I prefer a more natural look and like a bit of movement and that is always achieved in the clinic. The front of house team are always so lovely as well
