    First, thanks for checking this topic out. I formulated this Vitamin C serum (with ingredients as below) and it got recrystalized after 4 days. How can I fix this issue?

    Deionized Water: 25%
    1,3-Propanediol: 54%
    Ascorbic Acid: 20%
    Licorice Extract: 1%

    The serum was totally clear after I kept stirring the mixture in hot water (i mean double-boiled) for 10-15 minutes. But it got recrystalized after 4 days. Is it due to the 1,3-Propanediol?
