Lovely staff and great result!
I was very nervous as this was my first visit. Dr Salina was kind and patient. She listened to what I wanted and explained my options thoroughly and explained exactly what I would realistically achieve.
I have to say, I didn’t need to worry because Dr Salina did exactly what I asked. I was absolutely thrilled 2 weeks later with the results I achieved. So natural and yet just a better me. It gave me so much more confidence in myself. It was worth every penny. All the staff were kind. Good value for money. I will definitely return now.

I had Botox administered by Dr Salina two weeks ago and the results are amazing! I had Botox previously at another clinic, but Sisu is heads and shoulders above. Thank you Dr Salina for the flawless results.

Professional aesthetics clinic in Mayfair
It was a great Botox anti-wrinkle treatment with Dr. Selina. Very professional, knowledgeable, and thorough, with every step explained in detail. I am truly impressed by Dr. Selina for asking my preference to make sure I get the look that I want. Also, explained to me on the follow-up sessions. Highly recommend Dr. Selina and the lovely Sisu Mayfair to everyone who is looking for a professional aesthetics clinic in Mayfair and beyond.

Dr Pedram's touch is as light as a feather
Dr Pedram has the hands of an angel, as light as a feather! I have been having anti wrinkle injectables for 20 years now and I was absolutely amazed with how gentle the process was this time, he is amazing! Will definitely be choosing him every time now. Thank you, very impressed

Great doctor, not so great experience
Dr Padram at Mayfair was amazing. I absolutely love my results.
However, the blonde receptionist was very unprofessional. I had 4 emails and 2 text messages with my appointment time, but she rudely insisted I had got it wrong with no apology, leaving me waiting for nearly 20 minutes to have my treatment.
The treatment room itself was clean, but the vents of the air conditioning unit right above my head was filthy and covered in dust, not really what you want blowing into your face whilst having injectables.
You expect this from the NHS, not a private clinic in Mayfair

I went to see Dr Nila today for a Botox…
I went to see Dr Nila today for a Botox top-up after visiting Sisu for the first time two weeks ago, and my whole experience was fantastic. I was in and out within 20 minutes — while some might think that’s too quick, I personally felt Dr Nila was very confident and thorough. She asked all the right questions and made me feel completely at ease.
We chatted while she was administering the Botox, and I honestly didn’t feel a thing. My follow-up was just as effective as the initial treatment. Dr Nila was welcoming, highly professional, and I would absolutely recommend her.
