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.
They help to restore our skin to its former youthful appearance, as the material is injected into areas where it needs to be plumped up again and made to look firmer.
Dermal fillers come in different thicknesses, and in general, the thicker the product, the deeper it is injected into the dermal layer of the skin to help plump out fine to deep lines and wrinkles, such as naso-labial folds (nose to mouth lines), fill scars, contour the cheeks and chin or augment lips.
Dermal fillers tend to be broadly classified as being either non-permanent (resorbable) or permanent (non-resorbable) in their effect. In the 1980s Collagen was the first dermal filler approved in the US. However, the leading dermal fillers used by most UK practitioners are hyaluronic acid based products. Other non-permanent fillers to be developed include ones using polylactic acid and calcium hydroxylapatite.
Permanent fillers are not widely used but can give a longer lasting effect, or even a permanent effect, and may be recommended in some cases.
