Hi I was thinking about getting injections done using sedyfill body filler. I’ve done research and it says that sedyfill is manufactured by Maypharm in Korea. According to the website, “The body filler consists of 100% cross-linked non-animal hyaluronic acid, created using the unique HENM cross-linking technology” How do I know if this filler is authentic hyaluronic acid? I would hate for it to have dangerous chemicals in there or liquid silicone. Thank you.
