I have smile lines at 16 and I don't have any bloat on my face, just stupid lines. Can somebody give advice
smile lines are dynamic, and caused by a lot of things. over-expression, facial musculature, cheek fat distribution, bone structure (zygos), etc. ppl who don't have smile lines are ppl who have literally zero facial expression. it's definitely not aging. it's either expression lines or just ur facial structure (ppl with narrower faces, flatter midfaces, etc), or both.
to improve it: if u have bad posture fix it. ex: forward head posture exaggerates nasolabial shadows. also sleep well. chronic undersleep deepens facial folds/creases. and don't go out in the sun too much. use skincare with SPF in it. prioritize drinking...
