First up is an old school facialist who you need to seek out.
Sally from West One Beauty is the kind of therapist you hope to find everywhere, but in this day and age of 'any little course makes you a trained therapist' is sadly not the case.
Sally is old school and has the hands that only experience can give you. She also has absolutely no ego unlike some of the 'celeb' facialists out there these days AND doesn't charge more than a dermatologist for an appointment (don't get me started). Another score.
She has two salons, the one above in Marylebone and another in Camden. She works out of both on alternate days.
Go see her. You won't regret it.
