Correcting a downturned smile with surgery? (Photo)

The range of responses you are receiving relates to the complexity of your question. Important to the answer is if you have had any previous surgical procedures or injectables (Botox or some form of filler). Allowing any injectable to dissipate prior to pursuing any option is absolutely necessary. If you have had previous facial surgery, you may have nerve or soft tissue issues that also may need time to resolve. If these factors aren't playing a role, an in-person consultation is really important because you are describing a very dynamic process that is difficult to capture with still photos. With that said, I would offer that my overall impression is to not immediately consider a surgical solution. The third photo you provide appears to be a very natural smile, and perhaps some some form of creative repetitive muscle training/exercise would be beneficial. While this would not be considered a textbook approach, there is no downside, and it taps into our natural muscle training potential. I hope this doesn't throw too much into the mix for you, but I thought an alternate approach may be worth considering. Best regards.     

It appears from your picture that you have an over active DAOI muscle which is pulling down the corners of your mouth. You would be a  good candidate for botox. This takes only a few minutes to perform. This is not permanent. I hope you find this information useful. 

I would look into possibly botox and facial fillers before doing any kind of  surgery. A good cosmetic dermatoldogist or plastic surgeon may be able to give you what you are looking for without doing surgery. Good Luck.

Hi:It is difficult to clearly see exactly what is the actual reasoning for the muscle pull, however, I believe it has more to do with narrow upper and lower arch.  Making the both arches wider with porcelain veneeers could be one solution. However, clinical exam,  and study models are necessary to evaluate properly.Best,Dr. Maddahi

 Hi, I have performed many facelifts and neck lifts for over 30 years and have performed many minimally, invasive SMAS facelifts.  From the photos your cheeks are flat in the front, jowls are present, the chin is weak and there is excess fat and loose skin under the chin.  These factors combine to create a rectangular shaped face. 
 Following my beauty principles, women look the most feminine, youthful and attractive with heart shaped faces.  Heart shaped faces have cheeks that are full and round in the front.  Cheek augmentation with a dermal filler or using cheek implants for a permanent enhancement will create full, round cheeks that will feminize the entire face.
 A weak chin creates an imbalance making the nose appear larger, the mid face top heavy and the lower face look short that de-emphasizes the lips and allows early formation of a double chin.  Chin augmentation using a chin implant will add projection to the chin creating harmony and balance to the lower face.  I have found placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick and highly effective.
 If you have "jowls” these are sagging facial tissues and the main indication for some form of a SMAS facelift.  The underlying SMAS layer, of the face, must be dissected, lifted, trimmed and re-sutured (not merely folded or suspended with threads or sutures that will not last).  The excess skin is then removed and the facelift incisions closed.
 My most popular SMAS facelift is the minimally invasive, short incision SMAS facelift that has all the benefits of more invasive facelifts (traditional, mid-face, deep plane, cheek lift and subperiosteal facelifts) but with these added benefits:
very small incisions and no incisions extend or are placed within the hair.
minimal tissue dissection = less bruising and swelling = rapid recovery ( several days instead of weeks or months with the more invasive type facelifts mentioned)
can be performed in 90 minutes or less, with or without general anesthesia
no incisions within the hair = no hair loss
excess fat can be removed from the face and neck
excess skin removed from the face and neck
cheeks, chin and jaw line can be augmented with dermal fillers (I prefer Restylane Lyft) or facial implants
most patients fly back home to parts all over the world in as little as 3 days post-op
 I combine facial shaping with every facelift procedure.  When jowls are present, these should be done in concert and not alone or separately in order to create a naturally, more attractive face.
Hope this helps.

You are a candidate for Epigenetic Orthopedics/ orthodontics to grow your maxilla or a neuromuscular reconstruction.
What you are seeing is insufficient support of facial tissues.  Deep naso-labial grooves are usually relate to narrow maxilla.  
The is insufficient information from your photos to say more.  Do you snore, wake with headaches or have excessive tiredness?
You could roll up some gauze into rolls and place between your back teeth and slide your jaw forward.  You need lips to touch in relaxed manner and you can profile what can be done.  Ideally you wear trial appiances initially to see how muscles and body adjst over time.
