Cheek fillers, also known as dermal fillers for the mid-face, are injectable gels designed to add volume and lift to the cheeks. The most common ingredient used in these fillers is hyaluronic acid (HA)—a naturally occurring substance in the body that keeps the skin hydrated and plump. Over time, as collagen and fat decrease with age, the face can lose volume, leading to sagging cheeks and deeper nasolabial folds. By injecting fillers in strategic areas of the cheekbones or under-eye region, you can restore lost volume, enhance your facial profile, and even give the illusion of a mini facelift—all without surgery.
