@5128gap I think you might misunderstand how some people feel.
I don't mind at all other people using Botox, fillers or surgery.
No issue with it whatsoever, only feel a bit sorry for them if it turns out down the line it's problematic, like with certain types of breast implants (watched too much Botched).
I have a friend who had one very small (eye) cosmetic surgery done, and a couple do just the 11's and that's very effective and not noticeable.
However, many people do not stick at that and once doing that, they then do the whole forehead, which is noticeable or fillers, which I can usually spot (even on younger members of the Royal Family..)
I don't think people 'know their own face' better because they tend to see their face in repose, still or in photographs. If they saw a face of filler and Botox in movement, chatting, talking, emoting, they would see something quite different, often the 'uncanny valley' look which does make you do a double-take in a whole line of people (same with duck lips, they just jar the brain in some way even if done really well).
I am not against many very subtle tweaks or even jaw surgery if you want to go all the way, I know someone who had that in their late twenties, didn't really change their overall attractiveness though, because the sum of the person is more than the parts, and that person was already good looking in a noticeable way so having a slightly tinier jaw was neither here nor there. They may have felt more confident though, which is a factor not often considered. I had my teeth done later in life and even though it probably didn't make a dramatic difference to others (I seemed to be attractive and have many friends despite crooked teeth), it made a huge one to me and now I smile in all photos.
