Because I don't know your specific situation, I suggest uploading a selfie to help you analyze it.
The above three situations can be solved by face filling, cheekbone interpolation and rhinoplasty respectively.
Face filling method: use hyaluronic acid or autologous fat to mainly fill the concave parts. Then adjust the whole contour to improve the fullness and childlike innocence of the face.
Introversion of zygomatic bone: after a small amount of osteotomy is completed by L-shaped osteotomy, the zygomatic bone is pushed inward to make the whole curve smooth and the cheek narrow.
Rhinoplasty: This is easy to understand. In fact, many girls have reported that after rhinoplasty, they feel that their faces have suddenly become thinner and more refined. This is mainly because the three-dimensional degree is improved, and girls with poor contour conditions can choose rhinoplasty to improve their temperament and face value.
I hope my answer can help you.
