I’ve been going to Dr. Benji Dhillon for all my Botox and facial treatments ever since I moved to London five years ago, and I honestly haven’t looked back. He was the first cosmetic doctor I ever saw, and I immediately felt comfortable in his hands. He just gets it — the results are always natural, never overdone, and I always leave feeling like the best version of myself

Define is the best clinic in London. I would only trust Benji for my touch ups and Eden has completely transformed my skin with BBL. They are so incredibly friendly and I genuinely look forward to going to Define. I couldn’t recommend them more!

If I had the choice of rating DefineClinic any higher, I definitely would!
All the staff there are lovely, respectful and always happy to help!
I had Dr Sunny & Faye to help and carry out my composite bonding journey.
From my first appointment they were so helpful, trying to gain an insight into what I want in order to achieve my dream smile.
I had my final appointment this week to polish and complete my smile, and I am over the moon with the results.
Couldn’t recommend DefineClinic enough!
Thank you all! :))Joe Gaskell

This was my first time ever getting any cosmetic procedure done, and I’m so glad I chose to have this experience done at define with Rosie. Going into my appointment, I was feeling a little apprehensive as to how my results were going to turn out. I just wanted something to help get rid of a few lines on my forehead without anyone noticing that I had anything done. Rosie took all of my points into consideration and she exceeded my expectations. Not only did she try to calm my nerves by bringing me water and making sure my experience was enjoyable, she also made sure that I was completely comfortable with everything she was doing and she made sure that I had all the knowledge I needed before I continued with the procedure.
One thing I will say about define, it’s a little on the pricier side however, it is worth every penny. You are paying for quality and good results!
If anyone is considering going to define (especially if this is your first cosmetic experience), I would highly recommend booking with the lovely Rosie!
