To understand how dermal fillers work, we need to look at how the sugar molecule they’re based on works in the body. These sugar molecules are found in all the connective tissues, including the skin. They attract and retain water as part as the extracellular matrix. The collective effect is the creation of underlying volume, lending firmness and elasticity to the skin.

As we age, levels of these sugar molecules naturally decline. Our skin becomes dry and loses elasticity. Meanwhile, loss of fat under the skin and a reduction in bone density cause skin to sag.  Wrinkles start to appear thanks to repeated muscle movement and folds arise from loss of volume. Applying a topical moisturiser that contains the same kind of molecule may provide a short-term effect, however, for true long-lasting moisture and volume replacement deep within the skin, dermal fillers can be an option. Dermal fillers work to attract water and restore volume in the injected area, just like the natural molecules would do. The smooth, supple results look very natural and can last up to 24 months, depending on the product that’s been used.
