How do I achieve the V-shape jawline and get rid of my chubby face? (Photos)

You have a youthful jawline compared to the patient I see for facelift surgery. This makes any surgical intervention a challenge. Anything that would produce scars or have significant risks would need to be weighed against the potential benefits. In your case the potential benefits of jawline enhancement may be limited. 
Fillers have the advantage of little down time and immediate results. If you want to dissolve the filler you can do so immediately. The disadvantage of fillers along this area is they are used to mask aging by filling the face. This is unnatural and gives a boxy, male or fat appearance to the face. 
Face lift surgery can lift the jowls, directly remove jowl fat and tighten the skin. In patients with a weak chin (not forward enough), the chin can be extended with an implant or fat grafting. The disadvantage of surgery is the longer down time. Surgery provides a longer lasting result and reverses the aging changes.
I hope this helps,

The shape of a V is thin or pointed in the middle and as it extends posterior, it gets wider.That's what your face looked like before the fillers. You had a pointed chin and slight pre-jowel sulcus, good so far. Then you have lateral jawline soft tissue fullness and gonial angle hypoplasia. Treat this with a lower face lift and gonial angle implant and you will have your V jaw line.

Thank you for your question.Yes fillers gave you a perfect linear jawline but also made you a bit fuller.To obtain a V shaped face in a lady, I like to consider an oval chin implant and some form of cheek augmentation, either with filler or cheek implants, as to recreate the "triangle of youth".Buccal fat pad removal can also help in converting a rounder chubbier face into a more angular face.A facelift can also help in restoring the triangle but one needs the excess of jowls and neck skin to warrant this more extensive procedure.  You also look young for a facelift.Hope this helps!Kind regards,Dr. Marc DuPere, aesthetic plastic surgeon
