A very good experience. Dr Hass was professional, thorough and took the time to assess my face properly. The face mapping was very detailed, everything was explained clearly, and the recommendations felt considered rather than rushed. I felt very comfortable throughout.

I am a lady in my early 50s I was very confused to choose a clinic that can remove my double chin which was really annoying me and making me lose my confidence. I finally found Dr. Hass clinic. I am a person who doesn’t like surgeries or injections.. I was very worried but Dr Hass was a very experienced professional doctor who made me feel comfortable and relaxed. I personally didn’t feel any pain and when I saw the result I was amazed with the beautiful change … No more double chin 🥹🥹 It’s very important for all women to invest in their health and beauty.. I strongly recommend Dr Hass clinic and I would love to make another visit for different treatments 😊 Dr Hass you really changed my life by increasing my self confidence thank you so so much for everything 🥹🙏🏼🌹

I’ve been coming to Dr Hass for a long time now and I honestly wouldn’t trust anyone else with my filler. He always makes me feel completely at ease and really takes the time to listen to what I want, while also giving genuinely helpful and honest advice. He’s brilliant at what he does, couldn’t recommend him enough!

I visited Dr Hass for dermal fillers and it was my best experience to date. Dr Hass took time during the consultation to really ask questions to understand my needs and make the best recommendations for me to achieve my desired results. He was honest and personable and even advised me against treatments I thought I needed due to seeing others have these procedures online. He really cared about my results and being satisfied over anything else. I was nervous but he put me at ease and the results are amazing. Cannot recommend the clinic enough and I will be back!

Endolift A huge thank you to Dr. Haas! I had a big issue with sagging skin, especially on my neck, so I decided to get an Endolift for my face with an extended neck treatment. I saw the results immediately after the procedure—my skin was tightened, my facial contours were much more defined, and everything looked so beautiful and natural. I am extremely satisfied, the clinic is clean and gorgeous, and everyone there is so kind. Dr. Haas is truly one of the best doctors, and I highly recommend him to everyone!

I recently went to Dr. Hass at Dr. Hass Clinic for an Endolift treatment, and I honestly couldn't be happier with the results! I had quite a bit of sagging skin, especially around my neck and lower face. The moment the procedure was done, I could immediately feel the tightening effect. The results were amazing right away the sagging on my neck completely disappeared, and my facial contours were lifted instantly. Dr. Hass is wonderful, so kind, and extremely professional. He explained everything in detail and took his time to focus precisely on the sagging areas where I needed it the most. I am so satisfied with my experience, I will definitely come back in the future, and I highly recommend him to anyone struggling with similar issues. He is truly one of the best, and I am so glad I found him and chose him!

Lips I would thoroughly recommend Dr Hass and his clinic. He is incredibly thorough, professional and, most importantly, honest in his approach. Having visited a number of different clinics over the years, what really sets Dr Hass apart is his focus on achieving a softer, fresher and more natural look rather than making you look “done”. He has completely transformed years of previous lip filler for me, and my lips already look amazing — beautifully natural and so much better balanced. I’ve had so many people notice the difference and comment on how good they look. I couldn’t be happier with the results and wouldn’t hesitate to recommend him.

I spent years looking for an effective treatment for my jawline and came across Dr Hass's clinic on instagram. I am extremely happy with the results of endolift and a mini liposuction. The service was exceptional from beginning to the after care. Dr Hass always responds to queries and gives appropriate advice. I would highly recommend his services.

Would highly recommend the Dr Hass Clinic. From booking my initial consultation right through to aftercare, every interaction has been quick, easy and professional. After having Endolift on my face with exceptional results, I had no hesitation in booking an Endolift body treatment for my thighs. Due to the amount of loose skin, I had always assumed surgery was my only option. I didn’t want to trade sagging skin for scars, and I also didn’t have the budget or the time for surgery and a lengthy recovery. I was therefore over the moon when Dr Hass explained that I could achieve visible skin tightening results with Endolift. I’ve just had the treatment, so I’m now really excited to see the results develop! The level of care, expertise and attention throughout has been brilliant. I’m particularly self-conscious about my thighs, but Dr Hass made me feel completely at ease and comfortable throughout the consultation and treatment. The treatment itself was also practically pain-free. I genuinely wouldn’t hesitate to recommend Dr Hass and his clinic. He clearly knows his stuff, takes great care of his patients and, as an added bonus, is actually a really cool guy to spend a few hours, I’m now a country music fan too!

I am so lucky to have found Dr. Hass. I recently did an Endolift procedure on my body and couldn't be happier that I chose to go with this clinic. I first had a consultation where Dr. Hass went through the whole procedure in detail and made me feel heard. I then came in for the actual procedure, feeling quite anxious as I never had anything similar done. The procedure went through so smoothly, and the pain was very minimal. Dr. Hass ensured I felt comfortable, and was very patient with me the entire time. He is definitely at the top of his field, so I felt safe being in his hands. I'm still in the process of recovery but I have minimal bruising and swelling and everything is healing really well. I already told Dr. Hass that I will come to him for any future procedure or cosmetic enhancement!

I visited Dr. Hass for a non-surgical nose treatment and I couldn't be happier with the results. My nose was lifted instantly and the whole procedure was very quick and painless. I don't live in the UK, but I would absolutely travel back to London to have this treatment done again. I highly recommend Dr. Hass
