Hyaluronic acid fillers are used to help “fill in facial creases such as marionette lines” (extending from corner of mouth to chin) or the nasolabial fold (corner of nose to corner of mouth). They are also popular for creating fuller lips, diminishing vertical lip lines and elevating depressed scars, or adding definition to the cheekbones.
These hyaluronic acid fillers, unlike collagen, are non-animal based and thus require no allergy testing and carry no risk for infectious disease transfer. They have been used for nearly 20 years worldwide and became available in the US after surpassing the FDA’s stringent criteria for safety and efficacy. The product is pre-packaged and purchased by the syringe to avoid risks of contamination.
