Having a youthful appearance is not a big deal anymore with our hero - dermal fillers. Let's have a look on basic knowledge of dermal fillers.

The structure of the skin is supported by the extracellular matrix or ECM, for short, which gives the skin its unique elasticity and tensile strength. The ECM is a complex scaffold composed of proteins and fibers, mainly produced by fibroblasts. Its most abundant component is collagen, a protein that ensures the structural integrity of the skin. Fibroblasts stretch out through the collagen network and the resulting mechanical tension regulates collagen synthesis.

During the aging process, the collagen fibers deteriorate and fragmented collagen accumulates. As a result, the mechanical tension decreases and fibroblast activities impaired leading to decreased collagen production and an increase in collagen degrading enzymes. This reduces skin integrity and promotes a cycle of structural loss. The jelq is injected directly into the deep dermis where it shows an immediate filling effect and corrects the localized loss of volume. In addition, the microspheres serve as a scaffold. This supportive scaffold promotes fibroblast activity and helps to trigger collagen.Network strengthens the tissue connectivity in the dermis. Macrophages slowly dissolve the microspheres. The skin then regains structural support and elasticity with skin quality improving.

Depending on the filler that's injected, each filler behaves a little bit differently. If it is a hyaluronic acid filler, it can last between six months to about a year. Some types of fillers such as calcium hydroxyapatite tend to last a little bit longer. Other fillers such as polio lactic acid which is more of a volumizing filler and that stimulates your own body's collagen, can last up to two years. You have other permanent fillers that are FDA approved such as poly methyl methacrylate and those are usually permanent as their namesake they can last for a very long period of time.

No matter any procedure that is performed, especially when it comes to fillers, make sure that you follow up with a board-certified dermatologist.
