As mentioned in previous comments, the facial doesn't include extraction nor exfoliation and doesn't last a full hour, but the treatment is nonetheless very relaxing and my skin felt cleaned and moisturised afterwards. The therapist is friendly. She did a skin analysis and gave me a few suggestions on how to improve my skin.
The only annoying thing was that I had booked through Treatwell for a Wednesday afternoon, received my email confirmation and when I turned up, no one knew anything about it and the therapist wasn't in so I had to reschedule. Apparently, the beautician works there from Thursday and the rest of the week, but slots for Mon-Wed appear on the website. So if you book, make sure you call them to confirm day and time!
