I know that 22 is young, but I feel like my face aged more than normally due to having bone removed. I'm not sure about that filler compared to the ones I've had (thank you for the suggestion btw
but I did get fillers in an attempt to camouflage the sagging/bulging and it just made me look puffy and unnatural. The saggy area was still there, but my cheeks just looked bulgier to compensate.
I'm looking into facelifts with some doctors, but I'm worried they'll say the same thing. To be honest, I've never heard of anyone under the age of 30 getting a facelift so I'm not holding my breath.
