Dermal fillers are non-surgical injectable treatments used to restore lost volume, smooth wrinkles, and enhance facial features. Made from substances like hyaluronic acid, they provide immediate, natural-looking results, making them a popular choice for facial rejuvenation. Common treatment areas include the cheeks, lips, and under-eye hollows. Results typically last 6 to 18 months, offering a quick and effective solution for those seeking to combat the signs of aging or enhance their facial contours without surgery.
