How can my asymmetrical nasolabial fold be corrected? When I smile it appears to pull further. (Photo)

I recommend 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, J Plasma and peels to get the most conservative natural look. Please see a facial sculpting expert. Best, Dr. Emer

I appreciate your question very much.I would suggest a dermal filler injection that looks extremely natural and is a flexible gel. The best option will likely be 1 syringe of Restylane Defyne followed by a syringe of Restylane Refyne. See an expert, Dr. ALDO 

I think it would be a good idea to look at pre treatment photos, hopefully they have some with you smiling. I find that sometimes/most of the time patients have a natural asymmetry and when fillers are used it might accentuate that asymmetry, or the patient notices it more as they are looking in the mirror much more that usual.  If you had a Hyaluronic filler placed it can be dissolved to some extent if you really can't live with it.  Best of luckDr G

Your nasolabial fold is slightly longer on one side and almost confluences with the marionette line on the one side.
A smile is a dynamic feature and thus in most cases we some degree of asymmetry in everyone.
Most smile lines cannot be changed as they are a dynamic feature.
This is part of your uniqueness - don't try change it.

Thank you for your question.
Certainly, it is not unusual for our nasolabial folds to be asymmetric when we
smile. However, ideally, we all like to be as symmetric as possible. It would
be important to know if you have any asymmetry between your nasolabial folds in
a resting position. If so, injectable fillers might be able to assist in
improving the asymmetry both at rest and during expression. However, if there
is no asymmetry at rest, then the problem is most likely related to overactive
muscular activity on the right side. One could consider trying to improve the
asymmetry using neural modulators like Botox or Dysport. Certainly, it would
require a consultation with careful physical examination before I could give
specific recommendations. I hope this helps.

Nasolabial folds can be fairly easily treated with dermal fillers. An injection performed with a blunt tipped micro-cannula, as opposed to a sharp needle, is not only less traumatic, with less bruising and swelling, but also allows deeper filler placement with minimal lumpiness. The use of cannula will permit much more accurate filler placement, and your results will be much more natural looking.
You also mention that you grind your teeth. Have you considered having anti-wrinkle injections to your masseter (chewing) muscle? These large muscles, which can be felt in your cheeks when you clench your teeth, can be relaxed with anti-wrinkle injections, which may help minimise grinding, as well as slimming the cheeks.

With smiling (animation) it is not uncommon to have facial asymmetry which is natural to you but perhaps more evident after treatment because of closer after-inspection.  I agree that you should check your face for smiling photos with different degrees of animation, because one has to match the degree of expression to make an accurate comparison.  Nevertheless, our objective is to attain symmetry, if we can, to compensate for muscular or soft tissue variations related to over or under usage, trauma, or simply the result of heredity.  In your case, I suspect your predominate chewing on the right and teeth grinding contribute to your asymmetry, and I strongly suggest you consult with an experienced oral surgeon before you do a cosmetic correction.  A muscular imbalance may be present and certainly teeth grinding should be corrected to prevent TMJ. Only after oral surgeon consultation and any correction which may be needed, would I proceed with cosmetic correction.  
I see a deepening of your right NL fold but it appears to extend into your right ML longer on the right.  Consequently, I would recommend your injector use Juvederm Ultra Plus or Restylane Defyne to layer in the SQ area to match the degree of wrinkling.  I recommend the microcannula technique using the TSK SteriGlide to minimize discomfort and bruising.  As always, I suggest you find someone with vast experience in these particular techniques instead of just general credentialing and I suggest you confirm this with close examination of their pre/post treatment photos.  Best Wishes, Garry R.

Almost all of us have one side 'different' from the other; and animation with eg smiling will accentuate the difference. Fillers or placing material on the actual bone surface under the fold will help change the contour; but it won't change the asymmetry in all likelihood.
