Thank you for your question. You are asking if cheek implants will also help darkness under the eyes, or if you will have to get cheek augmentation and under eye fillers separately. I can help you with some guidance on this, in the absence of a picture or a physical exam. I’ve been in practice in Manhattan and Long Island for over 20 years, and I perform cheek implant surgery, often at the same time as a facelift, surgical fat transfers to the cheeks, as well as perform non-surgical cheek augmentation with fillers, using a special technique called Structural Volumizing. Treating the cheeks and the under eye area, also called the tear troughs, does require separate treatment. Cheek implants, which can be two separate implants for each each cheek called submalar and malar implants, do not reach up until the tear trough. Lower eyelid skin is much thinner at 0.5mm thick, than the skin in the cheeks, and have a lot of movement, so filler used in the cheeks is much thicker than a filler that would be used in the tear trough. If lower eyelid skin is so thin that it is revealing the anatomy underneath, then a filler can help as a barrier between the underlying anatomy and skin. However, if the darkness under the eyes is caused by pigmentation, discoloration of the skin, poor skin quality, or circulation issues such as iron deposits and pooled blood, than a different treatment is used to improve eyelid skin such as platelet-rich plasma (PRP), laser treatment, or a radiofrequency treatment. There are different ways to treat cheek volume and dark under eyes, but since these are two separate issues, and in areas with different anatomical structure, they do need to be treated separately. I hope you found this information helpful. Thank you for your question.
