As Grannyknot says, the face looks younger, but everything else still ages. The Daily Mail is always running articles about women who think they look half their age because they have had this procedure, that procedure etc etc, but actually they are deluding themselves because their clothes, their shoes, their hair styles and their make-up is so stereotypical of women of their chronological age, whatever that may be - and their faces look so like dolls that they end up looking older rather than younger.
Unless you are really unfortunate enough to have a face that really has aged excessively, and even then I would think 10 times, I would avoid surgery. You will look much younger just by finding a younger more fashionable hairdo, and having a good look at your clothes and make-up and gently urging them younger. Look at younger women, or women you perceive as younger when you are out and about, look at fashion magazines, oddly the colour supplements of Sunday papers are good for this, look in the shops, sees what's on trend, to use the current phrase, and then decide what suits you and what you feel comfortable in and buy it. Its a far less painful, cheaper and reversible way of rejuvenating yourself than surgery.
