Soft tissue fillers are commonly stabilized hyaluronic acid, in the form of a crystal-clear gel that smoothes wrinkles and folds or gives contour. Different types of fillers are specially designed and available for different purposes and effects, from eliminating tiny lines, correcting deep folds, enhancing facial contours such as cheeks and nose to sculpting and volume augmentation of the lips to perfection.

Factors such as age, skin type, life style and muscle activity as well as on the injection technique can affect how long a filler treatment holds its effect. Generally patients choose to have a follow-up treatment six to twelve months after an initial treatment of wrinkles or facial contouring. As for lip treatments, a follow-up is usually required after six months.
