Greetings all! I am happy to join you!  I have a question for you that suddenly dawned on me since I am fairly new to preservatives. I have a wonderful serum that I have been making for sometime now and have expanded to selling to more than just friends and family. I preserve my HA's and other small amounts of water based ingredients with optiphen,the other ingredients are oils .The burning question I have for you is : Do I still need to add more preservative to my final product? Thank you all for any help you can give me . |
