Fillers, also known as dermal fillers or soft tissue fillers, are injectable substances used to restore volume, smooth lines and wrinkles, and enhance facial contours. They are commonly made from hyaluronic acid, calcium hydroxylapatite, or poly-L-lactic acid. Fillers in Dubai are gel-like substances injected beneath the skin to add volume and fullness, resulting in a smoother, more youthful appearance.
