I had a lower facelift 10-years-ago - so shoot me! Essentially, it just refreshed my face, getting rid of the jowls that were beginning to develop and giving me back cheekbones.
As for cosmetic surgery for vanity being “a waste of a surgeons skills” as Patticake said. My surgeon specialised in Maxillofacial surgery in the NHS, working with facial and mouth cancer victims who need reconstruction, burn and road accident victims, etc. He also took a 6 month sabbatical some years before to work with children who had survived a war, but with terrible injuries in Rwanda. He also chooses to earn extra money outside of his NHS hours, providing elective cosmetic surgery!
