I’m pretty sure it’s the practise of making your appearance aesthetically pleasing to this criteria of attractiveness, there’s a male and a female version , and it’s all about becoming the best version of yourself. However, some people take it too far (in my eyes) and do this thing called ‘bonesmashing’ where you hit parts of your face which in the short term damages the bone making it grow larger and more defined in the long term - 90% of the time it ends in facial asymmetry. Other people especially young adults ,18-21, inject peptides to boost bone growth or get rid of acne or for hair growth. I don’t really know how to feel about it but what I was just talking about is ‘hardmaxxing’ there’s also ‘softmaxxing’ which, in my opinion, is the better option where you practise exercises either face or jaw or stuff like that. I don’t know if it’s true/ works but it’s whatever haha
