I have weak midface (weak infraorbital rims + cheekbones) in non-clinical sense. Should I think twice about getting implants?

Thank you for your question.  Because of your listed concerns regarding cheek and lower eye implants I would recommend trying dermal fillers as an excellent substitute. Not only does a filler such as Voluma allow for flexibility in contouring a particular cheekbone size and shape, but results can last for two years or more.  Just be sure to see an ASPS board certified plastic surgeon for an evaluation

Without seeing pictures of your face it is impossible to provide an useful answer. But custom infraorbital-malar implants provide anterior projection to the orbital rim and anterior cheek area that can not be achieved by any type of standard preformed facial implants.

  A full set of pictures are required of the face to determine candidacy for cheek implants, since both the cheeks and the cheek implants are three-dimensional structures. Cheek implants are composed of Silastic, are manufactured in a large variety of sizes and shapes which is designed to match the patient's unique  facial anatomy. The implants are placed through an intraoral approach under  a brief general anesthetic. For many examples, please see the video and the link below

 Hi, I have performed many cheek augmentations, over the past 30 years, using a dermal filler (I prefer Restylane Lyft) or with cheek implants for a permanent enhancement.  If you have a weak mid face which is primarily the cheek area, cheek augmentation with a filler or cheek implants would shape and define the cheeks.  Following the beauty principles outlined in my book on face and body beauty, men look ruggedly handsome with angularity in the cheeks, chin and mandibular angle.  I am going by some of your comments and assuming that you are male.  Angularity, in the cheeks, is created differently than full round cheeks (female ideal) in women whether using a dermal filler or implants.  You however need to be certain that the plastic and cosmetic surgeon understands and follows the proper facial aesthetics in order to get that specific look.  I have removed many cheek implants, placed elsewhere by other surgeons, that did not make the patient more attractive both male and female.   I have found silastic cheek implants, placed through a small incision on the inside of the mouth, to be very safe, quick and highly effective at creating the proper aesthetic shape whether it be in a woman or a man.  The emphasis must be on proper implants selection (size and shape) as well as proper placement within the cheek area.  Hope this helps.
