Hyaluronic acid fillers are the choice de rigueur for fighting the effects of aging by temporarily restoring volume—and a new formulation of the acid may be on the horizon. As opposed to the flowable gels that are currently used, the investigational injectable (to be named Aline HA) is a fine thread of solid hyaluronic acid. Like Restylane, Juvéderm and Perlane, Aline HA will be injected with a needle, but instead, is pulled in following the path of the needle making very thin or long lines easier to treat. Once placed in the body, Aline HA hydrates and softens into a gel, much like other hyaluronic acid fillers. Instead of injecting filler and hoping it gets deposited to the right place or massaging it into place, the needle can be repositioned if it’s not in the optimal location.
