Would I achieve noticeable results from filler in the nasolabial folds? 31 y/o (photos)

Frankly, at least from the photos, the nasolabial lines, while present, are not particularly prominent. More obvious in are the parallel laugh lines lower down that ring the sides of the mouth (particularly on your left side). For these, I have found that the use of a low viscosity, cohesive, malleable HA filler injected in a fanning technique to be particularly effective for reducing these. Very likely if these were treated, the smile lines above would become much less of an issue and would very unlikely require any treatment at this time. You would be wise to consult with an experienced board certified cosmetic dermatologist filler injector and best of luck.

Yes, you are a good candidate and should see noticeable results, in good hands.

Of course, an “in person” consultation is necessary.

I hope this helps,
best of luck !
