Liquid rhinoplasty - can my nose by made more symmetrical and can alar lines be corrected with fillers? (Photos)

Non-Surgical Rhinoplasty (NSR) A.K.A. Liquid Rhinoplasty is perfect to address bumps and lines to the alar of the nose. It is also perfect for a tip flip, giving the illusion of a raised nose tip and making the nose appear smaller. What NSR is not perfect for is lateral curvature and lines which can make the nose appear wider. For those issues a surgical rhinoplasty is the only reliable answer. So, make sure to review many before and after photos when deciding on an injector. All the best from Boston!

In some cases, yes, liquid rhinoplasty can improve mild asymmetry after surgical rhinoplasty, but it depends heavily on the cause of the unevenness.
Fillers can be helpful for small contour irregularities, such as slight sidewall or dorsal asymmetry, by camouflaging rather than reshaping the nose. However, fillers cannot correct true structural deviation, scar contracture, or cartilage asymmetry from prior surgery.
Alar lines are more challenging. If they are due to volume loss or shadowing, very conservative filler placement may soften their appearance. If they are caused by scarring, muscle pull, or nasal support issues after surgery, filler may offer limited benefit and can carry higher risk in this area.
Because you have had prior rhinoplasty, any nasal filler should be done very cautiously by someone highly experienced with post-surgical noses, as the risk of vascular complications is higher.
An in-person evaluation is essential to determine whether filler is appropriate or if other options, including revision surgery or non-filler treatments, would be safer and more effective.

The short answer to your question is that a low viscosity, cohesive, malleable HA filler can be used to correct certain nasal asymmetries, including those left by prior rhinoplasty surgeries. Very important to make sure to consult with an experienced, board certified cosmetic dermatologist filler expert, especially since the prior surgery has likely caused scarring and vascular changes that make the need for an expert injector that much more important. Hope this helps and best of luck.
