Cheek filler, also known as cheek augmentation or cheek enhancement, involves the use of dermal fillers to add volume and definition to the cheeks. As we age, the natural fat pads in our cheeks can diminish, leading to a loss of volume and a sunken appearance. Cheek filler injections can help restore fullness to the cheeks, enhance cheekbone definition, and create a more youthful facial contour. During the procedure, a healthcare provider injects the filler into specific areas of the cheeks 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 commonly used for cheek augmentation due to their natural-looking results and temporary nature. The effects of cheek filler treatment are usually visible immediately, although there may be some initial swelling and bruising. Over the following days and weeks, the filler settles into place, and the full results become apparent. Cheek filler injections can last anywhere from six months to a year or more, depending on the type of filler used and individual factors such as metabolism and lifestyle habits.
