Does having filler placed in the upper nasolabial fold (the part that's up beside the nose) look unnatural?

This is a very popular area for filler treatment and generally very satisfying for the patient. The area you're asking about can be particularly effective - filling the piriform aperture lifts the base of the nostril and even the upper lip a bit while giving a foundation for the nasolabial fold. In my opinion, this is necessary in most people asking for improvement in the nasolabial folds! Coupled with more superficial fill to lift the fold itself, the results are very natural. Make sure you find an injector who understands the anatomy of the area next to the nose because blood vessels run there and injecting improperly can lead to tissue necrosis! I hope this helps. - Dr. Leong

It would be easier to answer your question if you attached some photos, but generally speaking NLF fillers are performed very often and provide a good benefit in achieving great aesthetic results. But just like with anything , it is possible to overdo it as well. So see a good and experienced aesthetic provider who would listen to your concerns and who would have a good eye for a most natural result. Good luck, Dr. Daniyar
