What to do about loose skin in lower face at 23? (Photos)

You are not a candidate for any surgical lift. However, micro-needling with or without radiofrequency could be helpful and is good to do as preventive as well.

There is no way you need a facelift at your age. If you have heavy neck liposuction might be an option but I can’t tell from the photos

All people are going to have noticeable difference in their face from their teenage years to when they are in their mid-20s.
I don’t see an indication for facelift surgery.
To minimize aging, I recommend avoiding excessive facial sun exposure, and wearing sunscreen every day.
This is the best way to Minimize further signs of facial aging.
Facial aesthetics, including predisposition, for some facial aging is highly related to facial skeletal structure.
Issues related to the lower, 1/3 of the face are therefore often related to the shape and size of the mandible.
We can’t really make the mandible bigger in a simple way, but This does explain why some people develop loss of jawline definition, jowls and nasolabial folds at an earlier age.
