Midface filler, also known as midface augmentation or midface enhancement, refers to the use of dermal fillers to add volume and contour to the midface area, which includes the area between the cheekbones and the under-eye area. This treatment targets the hollowing or flattening that can occur in the midface with age, resulting in a tired or sunken appearance. During midface filler treatment, a healthcare provider injects filler into specific areas of the midface using a fine needle or cannula. The filler material is typically made from substances like hyaluronic acid, calcium hydroxylapatite, or poly-L-lactic acid. Hyaluronic acid fillers are often preferred for their natural-looking results and temporary nature. The goal of midface filler treatment is to restore volume and contour to the midface, resulting in a more youthful and refreshed appearance. This can help reduce the appearance of under-eye bags, dark circles, and nasolabial folds (smile lines), as well as improve overall facial balance and harmony.
