I went for an Endolift with Dr Hass. I did my research on the procedure and Dr Hass before deciding that this was the procedure for me and that he would do it, so I travelled from Hampshire to London to see Dr Hass. I must confess, I was a little apprehensive to start with, yet I need not have worried. Dr Hass took his time with me, was reassuringly knowledgeable and professional, with a kind, caring manner that put me at ease almost immediately. He certainly is a master at his work because the immediate results are fabulous. I am thrilled and look forward to this continuing to improve over the next 3-6 months. The whole booking process was quick and efficient, supported by great communication on the pre- and post-care instructions. I would not hesitate to recommend Dr Hass. I will be returning in a few months for review of my results to establish if I need any further tweakments. I won't hesitate to do this with Dr Hass again.

Had an Endolift with Dr Hass on Wednesday, with a review in a few weeks time. The procedure itself was around 90 minutes and apart from the anesthetic injections, it was mostly pain free. Dr Hass explained everything before he started and put me at ease. The aftercare contact has been great, Dr Hass has checked in the past 2 days following the procedure to ensure everything was ok and advised to contact him if I have any concerns. The clinic is light, airy and comfortable. I felt at ease and in safe hands and would recommend using Dr Hass if you are looking for a professional, experienced touch

I recently visited Dr. Hass for my very first masseter botox treatment, and the experience truly exceeded all expectations. From the moment the consultation began, Dr. Hass was extremely kind, sweet, and genuinely considerate of my nerves as a first-timer. ​He took his time to thoroughly explain the procedure, ensuring I felt completely comfortable and informed. Despite his careful, measured approach, the treatment itself was impressively fast and virtually painless - a huge relief! 😖 ​Dr. Hass combines professionalism with a wonderfully gentle and reassuring manner. I’m delighted with the care I received. Highly recommended for anyone considering masseter botox! ❤️
