If I have chin lipo and buccal fat removed, will I have loose skin after? (Photo)

In younger patients, usually under the age of 45, there is not significant problems with skin laxity and loose skin following submental liposuction however this is very dependent on your anatomy and skin elasticity as well as the collagen content of the skin noted on your physical examination. Likewise buccal fat removal when performed conservatively can result in significant improvement in fullness of the lower third of the face, and is typically not an issue in younger patients but there can be significant hollowing noted in older patients or with aging, particularly in an aggressive excision.
It would be best to discuss these topics and a consultation prior to surgery with your board certified specialist.  Best of luck.

More information is needed such as your age, and the extent of the inelasticity of the skin tone in your neck. The skintone is best determined at the time of the examination.  Fat removal can be performed above and below muscle in the neck in addition to a platysma plasty, however there's no skin removal. If there is loose and inelastic skin in the neck, then a lower face and neck lift is required.
