“…Nonpermanent fillers, such as HA and poly-L-lactic acid (PLLA), have been successfully employed to treat atrophy linked to linear morphea, scleroderma, LE, and LE panniculitis (LEP) (Gupta, Bhari, Verma, & Gupta, 2017;Ponzo, Carruthers, & Humphrey, 2017;Thareja, Sadhwani, & Alan Fenske, 2015) Permanent fillers such as polymethylmethacrylate and polyacrylamide hydrogel have also yielded excellent results in scleroderma en coup de sabre and LEP-induced subcutaneous tissue atrophy (Franco, Serra, Lima, D'Acri, & Martins, 2016;Gupta et al, 2017).…”
