Won’t be back! I had a few treatments done here on first impressions very nice place, friendly etc. I had 3 areas of Botox done and on my review they had to fix one of my eyebrows I also commented on the crows feet so more was put in. This did not last as long as any other Botox I have got from other places and when I brought this up I was told that is the way it was & only get a few weeks from it. I also had a lip flip - no issues. My biggest issue was the polynucleotides for under eyes. This was suggested to me from them when I had went in for under eye filler. I was told this would be far better so paid for the 3 sessions. I was told mild bruising for 24hrs. This wasnt the case for me they went swollen for a week luckily I work from home as you could not go out like that. On my second session they still were bruised and I queried whether i should wait she said no so it was done again and once again badly swollen. I had to wait 3 weeks for the last session so as the swelling finally came down I could see the results and there was zero difference. I rang and spoke to them about this and a consultation with the dr was made. I showed her the pictures & said I was very unhappy after paying near £1000 for a treatment they recommended and didn’t think I wanted the 3rd one done if no results. She advised me all would be better when I get the last treatment done & kinda brushed off my concerns so I stupidly trusted her and went ahead. Again bad swelling but in one eye this time. They didn’t take any pre/post pictures.This treatment is painful btw. It has been months now and if anything my eyes look worse than before I started. I am even considering under eye filler again with another clinic. They happily take your money and suggest treatments but once it doesn’t work or issues they brush you off.
