Ways to improve nasojugal groove/tear trough in addition to nasolabial fold? (photo)

It's difficult to see from your photos, but nasolabial folds can be improved with fillers for the folds themselves and to provide anatomical support with Sculptra for collagen building. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

This is a good question especially since you are only 19.  You have the beginnings of aging in the midface.  Due to your loss of volume in the midface, the nasolabial fold is also increasing. This is occurring on your right side sooner than on the left.  At this young age, I would recommend Fat transfer over an implant first.  This would solve the flatness in the cheek.  Both cheeks can be contoured at the same time.  This would also improve the nasolabial fold.  Fillers are a good option but would have to be maintained (repeated).  That is the downside to using fillers.  At your age, fat transfer would be the best alternative.  I hope this helps.

Both areas can be improved with synthetic fillers or fat transfer. Most fillers last 6 to 12 months. Longer lasting fillers have increased risk of lumps when place near the eye area. Fat transfer is very long lasting but has more initial swelling.
