Botox, tummy tucks, Brazilian butt lifts. You may have seen the posts - and adverts - on your socials.

Cosmetic surgery is on the rise globally. Last year there were 33.8 million surgical and non-surgical cosmetic procedures done worldwide. That’s according to a recent report from the International Society of Aesthetic Plastic Surgery (ISAPS).

We chat to Giulia Granchi, our reporter from Brazil, and Hyunjung Kim, in South Korea to find out which procedures are popular where they live. We also hear from Los Angeles-based writer Iris Kim and learn about her complicated relationship to double eyelid surgery.

And we check in with Dr Anthony Youn (@doctoryuon on Tik Tok) to ask him about how social media and celeb culture is changing what people ask to get done.
