My nose tip is also sagging and my mid-face is really long, but I recently had rhinoplasty
and they also corrected my nasolabial angle,
so my mid-face looks a lot shorter. I used to emphasize my cheekbones and put lip liner and highlighter slightly above the tip of my nose to make my mid-face look shorter, but surgery is the answer, seriously
ㅋㅋㅋㅋㅋㅋ They showed me reviews that were similar to mine, so I trusted them and I think it was a good decision to get the surgery! ㅠㅠㅠㅠ
