Microbial Contamination Testing Question
I am just wondering how this works! I will be making my own lipstick and have been advised to get this testing done. Anyone know the best, affordable place to do/send this? Anywhere in the North Carolina area? Do I just send one tube of lipstick?Also, how do I know if the local products I buy here have had this testing done(and passed)?! Is there some sort of sticker or symbol on the label/website that would allow me to know this information?!Thanks all!!
