cosmetic operations?
I can't really think of anything else that would be useful for someone who is young and doesn't have very obvious facial flaws (like a big bump or something)
There's
femur LL
Tibia LL
Femur nail removal
Tibia nail removal
Scar removal (laser, skin colored tattoo, etc)
scar concealing tattoos w/ art/patterns/etc
Hair transplant (maybe worth it if you truly have enough donor supply. I don't think its worth it for alot of guys)
Micro scalp pigmentation (dark colored tattoo dots) to conceal the scar of the hair transplant/crown thinning
I think there is an argument to be made that the above would make alot of men look better
Although there are things like chin/neck liposuction or buccal(cheek) fat removal, I am not sure they are better than weight loss for like at least 80% of people. There are things like 6 pack etching surgery, but I don't really see the point of it unless someone has reached like 9-11% bodyfat and is very stable at that weight for years and just doesn't want to go through the diet unpleasantness/less enjoyable meals to get all the way down to 6% bodyfat just to get all year around abs
I just feel like after LL and hair transplant, weight loss beats almost every operation by a long shot for at least 80% of people --and so optimizing the diet/sleep/routines seems like the next biggest appearance improvement aside from getting clothes that fit your body well
I know some dermatologists advertise armpit hair removal with laser, but I don't think most guys would care about that, it takes a few seconds to trim them down to a neat length if they are actually too long
I guess for some middle aged people, hair dye could be useful if they want to date younger people but I sort of think some people look better with salt and pepper/grey hair, something about it commands respect
I feel like maybe weight loss is best and then there isn't that much that can be done until someone gets older and then there is this world of facelifts, dyeing hair, wrinkle-related stuff, etc but I just don't know anything about that world or if its good or not
