Do I have a weak chin or just big lips?

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 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

I think your jawline is good but there is a bit of recession of your chin.  This could be augmented with a chin implant or injectable fillers.  

Dear Harr.yp, You have a slightly weak chin that could be augmented to provide a better balance to your profile. You appear to have full lower cheeks as well which may benefit from buccal fat pad reduction. It is common in patients with a slightly weak chin to also present with fullness in the lower cheeks and the combination of procedures can provide very nice results that will improve your overall facial aesthetics.
