Dermal filler is a substance made of hyaluronic acid, which is produced by the skin cells in the human body. Once injected into the skin it fills up with water and adds volume to the muscles. As we age, our bodies stop producing collagen and elastin both of which help to give us a youthful look and in the absence of both, facial wrinkles start to appear. The function of the filler is to iron out the fine lines and wrinkles and add volume to the facial muscles.

 

Most wrinkle fillers are temporary as they eventually get absorbed by the body. The majority of dermal fillers last between 6-18 months, however, the length of time can depend on a variety of factors including the type of filler used, the client's body and their lifestyle.
