What treatment is appropriate for a 22 year old with visible nasolabial folds? (Photo)

Hello Elisa.  Considering your age, we would suggest dermal fillers.  1 Syringe of Restylane, Lyft or Radiesse should make the area much smoother and address your concerns.  Best of luck.

It appears to me that injectable fillers could be used to improve your nasolabial fold.  Examining your entire face would be helpful to determine the best placement of the filler to benefit your nasolabial fold.
