Hi guys, I received my actives to make my vitamin c serum, super excited by the way! What I would like to know is which actives need to be refrigerated? I have read this before on the forum, but would like it in one location. If you guys know where I read this before, could you post the link for me? I have read so much valuable info here and know that you guys can help me! I have also read conflicting stories about refrigerating the finished product vs a cool dry place. Any suggestions on that? The actives that I am mainly wondering about are HA, Ferulic, Vit E oil, L-ascorbic. As well as SKB and propylene glycol. Your responses will help me tremendously! Thanks in advance!
