To Smooth out Nasal Labial Lines is It Better to Get Filler in my Check Bones or the Actually Folds?

It would be helpful if you posted a photo but typically if the nasal labial folds are not too deep and you have nice cheeks I would just fill the nasal labial folds.  If you have lost volume in the mid face evidenced by hollowing under the eyes or flattened cheeks, filling the cheeks will give a nice lift to the face and lift the nasal labial folds making them look less deep.  In some cases I do both areas.  Again, it depends on what each person needs.   

This is a great question. If you're concerned about the nasolabial folds or smile lines as they are sometimes called then injection of the dermal filler in the area of the actual nasolabial folds will give you the best results. However sometimes when volume is restored in one part of the face you may start to notice other areas of the face that are volume deficient such as the cheeks. This is why it's important to have an experienced physician evaluate you prior to any treatment.
