I had a filler injection done approximately 5 years ago. The person who inject me said it was ácido hialuronico y acido lactico ( Phiell g1) however I am not certain if this is true, regardless, After a few months, visible lumps began to appear. 5 years on the bumps where the injections took place remain visible as a from of granuloma. I am looking for a solution to get rid of the lumps or at least to minimise the volume, what are my options? does any one know a true expert in this field?
