This was originally listed under LRP as the brand..I have re-entered it now that MUA has Biomedic listed as its own brand
I've been using this on and off for years now. It really is the best way for me to incorporate vitamin C into my skincare routine without an extra layer of stuff. Plus since it is mixed right before each application, it is always fresh and potent, and has a long shelf life (if stored in a dry area). Much more economical than things like cellex-c, or skinceuticals. Plus this will never show up already oxided and useless at your door after being shipping during hot weather! Love it. One bottle lasts months.
