The biggest benefit from a facial is the 'feel good' factor, attributable primarily to the massage component. The exfoliation/ creams do not offer a very great benefit over some superior products, which can be used comfortably at home. Also, now with home microdermabrasion/ dry exfoliation tools, and home chemical peels, there is no definite added advantage to a facial, whatever its name!
However, one does 'feel good' and 'pampered' after a facial, which doesnt quite happen when massaging one's own face! So I guess facials are here to stay, but in patients with acne/ oily skin, it is better to avoid these, since overenthusiastic massaging and hydration can end up causing more pimples to break out!
