To have an understanding about what dermal filler to use, we need to know why we are using them. We all know that aging is a part of life, and as the years pass our skin may begin to look less vibrant, refreshed and youthful. It happens to us all, and it’s not fun, I know. When we are young we have a lot of collagen, elastin and hyaluronic acid in our skin, which gives it volume, support and that plumpness. When we age this brakes down and the results are facial lines, wrinkles and saggy skin.
