  Microbial testing and stability testing

  Posted by esthetician922 on May 30, 2020 at 3:41 pm

  I bought the microbial tests to do a preliminary but I wanted to send off my formula before selling to the public. Does anyone know where I can send it off to a lab in the US. I live in CA if that matters. How reliable are at home microbial tests? 

  Thanks!
