Just moved to Phuket. One of my first observations is… cosmetic?

I’ve noticed a ridiculously high amount of people with lip injections, Botox, etc.

FWIW — American, just moved to Phuket from CNX after 10 years. Not trying to insult or criticize anyone.

I know it’s become more popular in the past few years, but can someone explain? Is it a particular (sub)culture, or did I fall off somewhere?
