Katia is very nice, I feel the treatment was effective, although it's something which needs to be done regularly so one session won't massively change your skin.
Downside is the venue is in the basement of a hair salon so a bit confined and dark.
It was nice overall but it lasted less than one hour and I was expecting to have a peel too. In the end it was just an ultrasound with several cream applications and a mask. So for me it was unsatisfactory. The lady was really nice though.
