Dermal fillers are made of various kinds of natural and man-made or synthetic materials that have been developed over the years for injection into the skin.
As the skin ages, it gradually loses some of its collagen and fat. These are the materials that prevent the skin from becoming saggy. Thus, as we age, our skin can become thinner and more wrinkled and lined.
Dermal fillers help to restore our skin to its former youthful appearance. Material is injected into the skin in areas where it needs to be plumped up again and made to look firmer.
Fillers come in different thicknesses, and in general, the thicker the product, the deeper it is injected into the dermis (middle layer of the skin - see diagram below) to help plump out fine to deep lines and wrinkles.
