What is wrong with my side profile? Cheeks, chin? (photos)

This will depend on the final results you want to achieve. Facial sculpting and contouring of the face can be created with well-placed fillers (Voluma, Radiesse, Bellafill) and Sculptra, which would give improvement in facial balance. Implants or fat are alternatives. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

An Irregular Trichophytjc Forehead Lift and Hairline lowering which we developed will give you a more proportional face. Hair will grow thru the scar so it is not seen if properly done by an experienced surgeon.Also cheek implants can give you what you want or you can start with Voluma to see if you like it.

The side profile demonsrtates a very mid weak chin profile, esp compared to the model.  A small chin implant can augment the chin forward.  For many examples, see below

Your facial profile has three issues that make it look off. These include a some degree of chin recession, a very high radix to your nose and too much nasal tip projection. The combination of a chin augmentation and a rhinoplasty that deprojects the nose and lowers the radix would be helpful to your profile.

I think a little filler in your cheeks is what you need to feel more proportioned. Definitely don't add to chin. A like Radiesse or Voluma for the cheeks.

 Hi, I have performed many facial shaping procedures using dermal fillers, silastic facial implants (cheek implants, chin implant, lip implants), liposuction and/or facelifts for over 30 years.  From the photos, your cheeks are very flat in the front and the chin is weak.  These combine to create an elongated, oval shaped face.  
 Following my facial 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.
 I have performed many Chin Augmentations using chin implants for over 30 years.  From the photos, your chin is weak.  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 silastic chin implant will add projection to the chin creating harmony and balance to the lower face. 
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for cheek and chin implant surgery.
Hope this helps.

Hairline lowering and forehead reduction can be achieved using the Irregular Trichophytic Hairline Incision technique that we described many years ago. I suggest you consider an  implant to improve chin projection and jawline definition. Cheek contour can be enhanced with the injection of fillers or your own fat or placement of a cheek implant. These changes will provide a natural more feminine appearance.
