How can I balance a nasolabial fold that is deeper on one side and make it less noticeable? (Photo)

Implants are the next step when you want to correct imperfections permanently and are easy to put in and easy to remove.

Hello - thank you for the picture and your question.  Of course it is best to be evaluated in person; however, I believe that fillers in conjunction with laser treatments will lift and tighten the skin.  You are not at a lost.

There are a lot of options for improving the nasolabial folds and this often means fillers for the folds themselves but also lifting around the mouth and cheeks to build underlying anatomical support. In our practice we combine sculptra with other fillers "layered" on top and lasers, rf treatments and peels to get the most conservative natural look. Please see a facial sculpting expert.

Dear 6735anon,an examination would provide a lot of details but generally speaking, dermal fillers are a great option for nasolabial folds. Fillers can balance your asymmetry. You should know that it is not a permanent solution and the effects of fillers will disappear after a few months. I would suggest you to consult a board-certified plastic surgeon who is an experienced injector. Daniel Barrett, MD, MHA, MS

Fillers are and excellent way to balance this.  The newer Vollure from Allergan has worked very well here.  Properly placed on the deeper side I think you could acheive a great balance.

Most of us have some natural asymmetries in our faces, so this is normal! However, dermal fillers are a great option to correct facial asymmetries to give a more "balanced" appearance. A skilled injector will asses your concerns during the consultation and inject the appropriate amount on each side to achieve a more symmetrical appearance. This can mean injecting more product on one side vs. the other. There are several new fillers on the market, including Restylane Refyne and Defyne and also Juvederm Vollure, that I am seeing excellent results in treating nasolabial folds. Good luck! 

Fillers are an excellent option for treating prominent or asymmetric nasolabial folds. Fillers to the cheek may soften the nasolabial folds to some extent, but often times, the nasolabial folds need to be injected as well. Juvederm is a great option for treating this area, in addition to some other fillers such as Restylane. A proper physical exam by a facial plastic surgeon who is experienced with filler injections is necessary in order to determine the best treatment option for you.
