Painful oozing at Sculptra injection site after liquid facial

Has anyone heard of patients having oozing of clear fluid at the injection sites of Sculptra within a few weeks of treatment prior to or after their changing of formula? My mother had painful oozing- the area around the sites was diagnosed as chemical burns- the doctor who injected claimed acne and did not mention any option to remove the Sculptra. This has been going on for 3 years and has permanently scarred my mother's face and is likely chronic. Any information would be helpful.
