Is there a permanent solution that can make my lips look more symmetrical/even? (photos)

This is my expertise and a huge portion of my practice. Asymmetry is normal and expected. Buccal fat pad gives slimming not symmetry. Masseter botox will make you slimmer and make the jawline more loose. Fillers help give shaping and contouring. If you want perfect or close to perfect symmetry you need maxillofacial surgery or implants customized. I suggest seeing an expert to go through all options. Most of my younger clients use fillers to give them shaping especially on the cheeks, jawline, and chin which make the face look more slim and tight; and threads such as PDO or Instalift can build collagen and support the facial shaping and skin looseness over time, slowing down the aging process and given the face a more “snatched” look; and morpheus8 or PiXel8 deep microneedling RF can tighten crepe skin especially on the neck and jawline and is great for long term tightening of the full face, neck and chest; its often used to give the face a slimmer more sculpted look because it tightens the skin and gives lift. an early face lift can be performed as well even in younger clients if they want a different facial shape, maxillofacial surgery with bone breaking or shaving can also be done. For facial slimming a combination of treatments are always needed. Options include: 1. Buccal fat pad removal to reduce fat on the lower face 2. Factite or Renuvion/J Plasma to tighten the lower face, jawline, and chin to reduce fat and give the jawline and neck tightening and shaping. 3. Botox to the masseter to reduce the muscular size of the jaw giving the face an illusion of being more slender 4. Fillers to the jawline, chin, cheeks, temples and brow help to shape the face and make it more angled and defined Always use at home derma rolling (see link to Emerageskin x anteageMD roller plus stem cells/hyaluronic acid ampules) and peels like emeragecosmetics enlighten or aerify that can be used to improve skin quality and tighten the skin while improving wrinkles, pigmentation, acne, and Melasma. See an expert who does facial shaping with surgical and non surgical methods to get a comprehensive option. Best, Dr. Emer.

The ideal candidate for the Elelyft, or upper lip lift, is someone with a philtral length of 14mm or longer, no upper dental show, and/or a thin upper lip. The nasal base to mouth width ratio needs to be taken into consideration to avoid leaving the lip corners down. 
The lip lift can address asymmetries and can be combined with a nose job. The corner of the mouth issue will not be addressed with a lip lift. I personally do not think that it subtracts from your appearance. 
Consult with an experienced lip and nose surgeon for a complete range of options that are appropriate for your situation.

A lip lift can improve the symmetry of your lips.  However, asymmetry is one of the most difficult things to correct.  The procedure will resect more skin from one side in an attempt to correct the asymmetry but no one can guarantee a perfect result.  A lip lift and rhinoplasty can be done simultaneously if desired or done separately.  You may want to do the rhinoplasty first to see if that has any effect on your asymmetry.Best Wishes,Gary Horndeski, M.D.

Yes, you have a mild lip asymmetry which can be corrected with make up and/or filler. I do not think that you need a lip lift since distance between you nose and Cupid's bow is within normal range. To create more symmetric upper lip, an incision along the lip border (vermilion, white role) is needed. Scar may not be predictable? Hope this helps.

A subnasal lip lift is not going to raise up the right vermilion border of the upper lip, only a direct vermilion advancement can do so which will also be permanent 

That's a great question. An asymmetric lip lift could possibly be used to address your upper lip, and some studies have demonstrated that both procedures can be done. Alterations to the upper lip can affect the nose, and alterations to the nose can affect the lip. Because of this, if you were to get both of these procedures, I would at least get them at separate stages.Another longer term option that wouldn't interfere as much would be something called dermal fat grafting. This would be taking a very small strip of skin and fat from an inconspicuous location and placing it the right side of your upper lip to give you more volume on that side.Either way, I would recommend you consult with a board-certified plastic surgeon for an in-person physical exam. Ideally you should find someone who is comfortable and experienced with both techniques so that you and your surgeon can make the best informed decision.Good luck and I hope this helps!
