This is 3rd time I see Dr Sef, and I can say I am sticking with him for the long term. I have used a regular who did a great job, but Dr.Sef tops him, plus the atmosphere is perfect, great ambient music, plus a clean and sophisticated surgical room and waiting area too. Dr Sef makes me feel at ease, we have good conversations and a good laugh. You are getting a professional treatment in relaxing surroundings.

I've been a patient with Dr Sef for around 4 - 5 years. Previously to this I've been treated by other companies and was left extremely dissatisfied. First meeting Dr Sef he corrected what looked like the Michelin man and sculpted everything perfectly.<br>When arriving for regular top ups you're made to feel relaxed, comfortable, not judged and at ease. Very well looked after, clean clinic with perfect aftercare.

The clinic is absoloutely gorgeous and Dr Sef was so lovely and made me feel really comfortable. He is warm, welcoming and extremely professional. I am obsessed with the results and will definitely be coming back.

Where can I start. Dr sef is a legend! I've been seeing him for three years now and always had VIP service. I've been to other clinics but they come nowhere close. He is professional, invested and always takes his time to listen to your concerns and ensures you are happy before you leave. He has literally changed my life and cannot recommend him enough. If you are nervous you shouldn't be. He is a master of his craft and having been other places they come no where close. Don't go anywhere else you will be disappointed. PS make sure you go hybrid !

I’ve been fortunate to work with Dr Sef for the past seven years, during which time I’ve received penile filler treatments along with regular top-ups. First and foremost, you genuinely will not find a nicer, more personable doctor.<br><br>I recently visited Dr Sef’s new clinic in Mayfair, which is in an excellent location, spotless, discreet, and very private. From the moment he greeted me, what stood out most was how personal the interaction was.<br><br>Despite not having seen him for around two years, he remembered my occupation, asked after my family, and even commented on my weight loss. That level of attention to detail really speaks volumes about the person he is and the care he has for his patients.<br><br>Historically, I’ve had annual fillers with fantastic results, and lasted well past the 12 months. However, last April I mistakenly attended a different clinic on Harley Street that shared a logo very similar to Dr Sef’s previous branding. I genuinely believed the two were affiliated, which they absolutely are not. While the service there was acceptable, the “premium” filler used lasted less than six months, despite being marketed as lasting 12–18 months. This is not something I was used to from many fillers received from Dr Sef.<br><br>Worse still, I was left with lumps and a misshapen result, which understandably had a significant impact on my confidence. When I returned to Dr Sef last week, he was able to correct the lumps, preserve the existing filler from the other clinic, and restore both the shape and my confidence through an additional course of treatment.<br><br>One moment that really stood out to me was when I mentioned returning in three months for another top-up. This would have meant additional income for him, yet he advised against it and suggested waiting longer. That honesty genuinely surprised me and perfectly demonstrates that Dr Sef prioritises patient wellbeing over profit.<br><br>What I’ve learned from this experience is simple: if something works perfectly, don’t change it.<br><br>Dr Sef, I’ll only be trusting you with my treatment from now on and thank you for being a genuinely nice bloke!

Professionalism at its best. Dr Sef knows exactly what he's doing, he makes you feel reassured and relaxed before, during and after procedures. He genuinely cares about what he does and who he's with.<br>I've been back four times and will definitely return, recommend to anyone thinking of using Aiva clinic.

Dr. Sef is always warm, welcoming, and highly professional. I’ve been going to him for years for all my treatments, and I wouldn’t trust anyone else. He treats you with genuine respect, kindness, and care like family. He takes the time to listen, truly understand your needs, and delivers consistently exceptional results. The quality of service, attention to detail, and aftercare are second to none. His clinic is spotless, hygienic, and beautifully calming, making every visit a comfortable and reassuring experience. His treatments offer great value, and the level of trust and care he provides means I’ll be a customer for life.
