Twelve-Month Data on a Poly-L-Lactic Acid Biostimulator

A prospective multicenter study in the Aesthetic Surgery Journal followed patients treated with a next-generation poly-L-lactic acid biostimulator in the nasolabial folds for a year, reporting effectiveness, satisfaction and safety. Biostimulators are a different treatment from hyaluronic acid rather than a longer-lasting version of it: they deposit a material the body answers by making collagen, so the result builds over months and fades over years. Durability data therefore matters more here than it does for a gel that dissolves.
