Supermodel Christie Brinkley and daughter Alexa Rae show off cosmetic surgery

Supermodel Christie Brinkley and her daughter Alexa Rae Joel chose to support each other and decided to plan their cosmetic surgery treatments together.The 56-year-old model had a face lift, while 24-year-old Alexa - Christie's daughter to musician Billy Joel - had a long-awaited nose job to correct a facial feature she wasn't happy with. "I was thinking about getting this for years," Alexa told People magazine. "[My nose] always bothered me a little bit. I was self-conscious of pictures taken from the side. To some people that's vain, but at the end of the day, we all want to feel pretty." While this was Alexa's first time under the knife, her mother may have a longer history of plastic surgery, according to practising cosmetic surgeons, who believe the model may have had non surgical treatments to boost her complexion. Dr Michael Salzhauer told Make Me Heal: "Christie Brinkley looks great certainly with the help of Botox, dermal fillers and a good skin care regimen." Having a look at the way a mother has aged can also be beneficial to daughters who are planning cosmetic surgery, as it offers a useful insight into the way skin is likely to age depending on genetic factors. Using sophisticated 3D computer modelling, surgeons are increasingly able to analyse the ageing process in mothers with similar facial features to their daughters, which can help younger women plan cosmetic surgery more effectively.
