Filler, composed of hyaluronic acid (HA) naturally present in our skin, works by attracting moisture and enhancing skin elasticity. Administered into the dermal layer or periosteum, it effectively diminishes facial wrinkles, restores facial volume, and enhances facial features, instantly refining contours for a smoother look. Depending on the selected filler type, results can last anywhere from one to two years, offering long-lasting rejuvenation.
