Facial fillers (otherwise known as dermal fillers) are injectable gels used to restore or add volume to the face. Fillers vary in density (thickness), which determines the area they can be used in, whether that is to provide lift or contouring, create symmetry, or enhance a particular feature such as the lips.
Facial fillers are a type of facial injectable. Facial fillers literally fill in a wrinkle using a synthetic or natural ingredient.
Fillers can also be permanent or temporary. A permanent filler can provide lasting results.2 Non-permanent fillers, such as JUVÉDERM®,5 can have durable long-lasting results (up to 24 months, depending on the particular JUVÉDERM® filler )6,7 but your body is able to metabolise it and eventually the results will fade.5
HA facial fillers are fillers that are injected directly into the skin to reduce the signs of aging and improve overall skin quality.3,9 They also add volume, to either restore volume lost over time2,3 or to provide a subtle enhancement.4
HA is a naturally occurring sugar found in the body that maintains the moisture in our skin by binding water molecules.5,11 It’s found in our connective tissues, including our skin.5,11 In fact, about half of the HA in our body is found within the skin.11
As we age, our skin renews itself more slowly and produces less HA,10,11 collagen and elastin, leaving us with thinner skin in which wrinkles and folds may start to appear.11 Adding moisturisers may provide a short-term effect; however, HA facial fillers can add moisture to the deeper layers of the skin.5
