What do I need to improve my weak chin? (Photo)

"A formal evaluation would be needed to determine what's best. Many of my patients try to avoid surgery, so we perform a non-surgical chin augmentation treatment with injectable fillers. Fillers like Radiesse, Voluma, BellaFill as well as Sculptra are injected into the area, improving the overall appearance of the lower face and balancing the jaw and lip harmony. We use cannula injections to meticulously contour and project the chin, soften the chin along the jawline and improve the chin crease.

Implants are still a great option once you are 100% positive that you are ready for a permanent enhancement.​ I suggest getting a consultation with an experienced cosmetic dermatologist and facial sculpting expert; our practice is located right here in Los Angeles. Best, Dr. Emer"

As you mention, a chin implant or fat transfer (which is a living filler) works wonderfully in cases of mild to moderate microgenia (small chin). The photo you provide does not provide enough information to make any meaningful suggestions in regards to the tissue accumulation on the side of your mouth. Anything from a facelift to skin tightening procedures to micro liposuction to tactical filler can help this type of problem, but nothing more can be said, in my opinion, without more photographs, or an in person exam.
A number of procedures can make the lower eyes more “fox – like“ including surgery, directly on the eyelids (e.g. canthoplasty or canthopexy) and an endoscopic, med, facelift and brow lift (assuming you are a candidate for those procedures). By modifying the tissue around the eyelid under magnified vision of the endoscopic camera, the eyes can be tilted in such a way as to make them more seductively appealing while addressing any pulldown of the lower lid, making it more more almond shaped.
I hope this helps. Remember to seek out the advice of perhaps 2 board-certified plastic surgeons during your expiration to see if what they suggest is right for you.
