    Author : Gabriella Sverlinger; Felicia Norman; Nora Othman; Wilma Hämäläinen; Michaela Thyberg; Maja Jonsson; [2023]
    Keywords : Polylactic acid; degradation rate of PLLA; physio- chemical properties of PLA; injectable PLLA;

    Abstract : Poly(lactic acid) (PLA) is a polymer chain consisting of repeating units of lactic acid (LA) used in various biomedical applications because of its biocompatible features. It is commonly used as a subdermal filler and constitutes as the main ingredient in SculptraR, which is a collagen regenerating filler used to treat lipoatrophy of the cheeks or to rejuvenate the skin.
