I have really sensitive skin too, but the best facial I have ever had was at the Perfect Health Spa in Richmond.

They do a complete mapping of your skin and actually chart your problem areas (ex, dry skin, skin pigment change) and they help you come up with a really good way to keep your skin looking healthy. The use the DERMALOGICA products on your face.
This place also has an awesome room to have a spa party in, My MOH booked it for my birthday and we got pedicures and manicures in this room that had a big projector screen in it. We had such a good time there
