After a lower facelift i am still jowly. my doctor said its because my chin is small. is this a possible reason?

Yes, a small chin can contribute to a jowly appearance even after a lower facelift. A small chin can make the lower face appear less defined, which can accentuate the sagging skin around the jawline and create a jowly look. In some cases, a chin implant or other chin augmentation procedure may be recommended in addition to a lower facelift to achieve optimal results.
