A whole lot of people from the "Democratic" Republic of Congo do it too.
TBH I don't even care WHY you do it: as someone said, a whole lot of people want to change their appearance, mostly for bs reasons. But while I'm not a fan AT ALL of esthetic surgery, it's not as wide-spread (because it's expensive) and I feel it's mostly less dangerous (as it's still a medical procedure). On the other hand this shyt is cheap and not medically assisted at all, so you see girls and guys with pink fukked-up skin with pimples and shyt...I wouldn't care one bit if this was somewhat "temporary" and without or with little medical risk, but it isn't.
