The Amsterdam Kliniek uses fillers produced on the basis of hyaluronic acid; this type of filler is the most frequently used filler worldwide. Hyaluronic acid is a sugar that naturally occurs in the skin. It absorbs water and gives the skin a youthful appearance. During the aging process, hyaluronic acid loss causes deterioration of the thickness and structure of the skin, resulting in wrinkles. Hyaluronic acid injected into the skin as a fillers treatment can significantly improve skin structure, strength and elasticity. Fillers can create volume in places where the subcutaneous fat pads have shrunk or sagged, such as the cheeks. Thinning lips can be enhanced.
