About dermal fillers
Dermal fillers come in many forms and brands. The most commonly used facial fillers provide temporary results and are biodegradable. They require repeated applications over time as they are broken down by the body.
Dermal fillers are made from a gel-like cross-linked material known as hyaluronic acid (HA), and are similar to collagen, a natural component of skin. HA is hydrophilic (attracting water) and contributes to skin and connective tissue hydration. It supports the skin’s natural collagen and elastin.
Hyaluronic acid dermal fillers are reversible with an enzyme. This enzyme can be used if the desired result is not achieved or in case of medical problems.
Dermal fillers can restore volume to cheeks. They can smooth lines and wrinkles for example around the mouth. They can firm key facial structures and define the shape of structures like the lips. Static lines and volume loss are best treated with dermal fillers. Dermal Filler can also be used to reshape the nose, (a non-surgical rhinoplasty) add volume or shape to the chin and add definition to the jaw line. Jowls can be improved by adding volume to the cheek and jawline regions of the face. Dark shadows below the eyes can be transformed with a tear trough technique.
There are many dermal filler products on the market and they vary in thickness and consistency depending on where they are to be used. Fillers last between 6 and 18 months depending on the injection site, with lip filler lasting approximately 6 months and cheek filler lasting up to 18 months.
Brands currently used include Intraline, Juvederm, Revolax, Radiesse and Teoxane.
Fillers are non-prescription products that require skilled injection technique around key anatomical structures of the face.
Those who are pregnant or breastfeeding should avoid dermal fillers. Those with previous hyper-sensitivity to filler and those with infected skin should also avoid treatment. People taking anti-coagulants (blood thinners) are more at risk of bruising, but are still able to have dermal filler treatment. Patients who have had cold sores in the past are at risk of recurrence after lip filler treatment. They are advised to use Zovirax (aciclovir) anti-viral cream for 7 days following treatment.
