I had a great experience at my recent visit to Dr Hass Clinic. The clinic itself is perfectly located – beautiful, clean, and feels very calming. Dr Hass and his team are highly professional, and communicated well with me before and after treatment. I felt comfortable and looked after throughout my visit. I was also really impressed with the aftercare and overall attention to detail. I would definitely recommend the clinic and will definitely be returning.

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 🥹🙏🏼🌹

After seeing phenomenal results from my first Endolift treatment on my lower face, I decided to have the procedure again, this time targeting loose skin on my thighs. Once again, I’m really impressed with the results. It’s only been a month and I’ve already noticed a significant improvement in the firmness and appearance of my skin, and I’m excited to see how the results continue to develop. Dr Hass has been fantastic throughout. He is incredibly knowledgeable, professional and reassuring, and is always very responsive whenever I have a question. I feel completely confident in his hands and wouldn’t hesitate to recommend him.

I had such a great experience at Dr Hass clinic. The service was amazing from start to finish. Dr Hass was so friendly and accommodating. He took the time to really analyse my face and understand what would suit my features, and it was clear that he knew exactly what he was doing. He did such a great job of balancing and enhancing my features while keeping everything looking natural. I’m genuinely so happy with the results and would definitely recommend the clinic!

Out of all the many places you can go for your Botox in London, and specifically in the Mayfair area, I am so grateful to have found Dr. Hass. He is highly skilled; having trained in surgical ENT prior to setting up his clinic. His background gives me complete confidence in his deep, anatomical knowledge of the face and neck. I have now seen Dr. Hass a couple of times—some treatments for medical conditions, and some for beauty enhancement. I have been delighted with the results. He listens to exactly what you are hoping to achieve, and importantly, he is totally transparent with pricing and the units of the product used. I will definitely be going to see Dr. Hass again in the future. I value his expertise and always follow his advice. With Dr. Hass, you are in safe hands.

I had Endolift with Dr Hass about three months ago and I’m so happy with the results. My skin feels much tighter and my face looks fresher and more youthful, but still completely natural. I had my three-month check-up today and it was really nice to see how much of a difference it’s made. Dr Hass and the team have been lovely throughout

Great experience with Dr Haas! I was honestly so nervous about getting an Endolift, but Dr Haas completely put me at ease. He has such a reassuring manner that really helped calm my anxiety. The procedure itself was very manageable and went really smoothly. I am already so happy with the results and can't wait to see the final outcome! So glad I went to him!
