Dermal fillers, also known as soft tissue fillers, lip and facial fillers, or wrinkle fillers, are injectable substances used to enhance facial contours, smooth lines, and restore lost volume. These gel-like substances are injected beneath the skin to create a more youthful and rejuvenated appearance. The procedure is a popular non-surgical cosmetic option for those seeking to address the signs of aging, such as fine lines, wrinkles, and volume loss, without the need for invasive surgery.
