    I made my vitamin C serum about 13 days ago.  I discovered in the retain I noticed a precipitate or crystals at the bottom of the container. Is this normal with this type of formulation? The stability doesn’t have crystals for the same length of time.

    Which form of vitamin C are you using? What pH are you at? Can you share at least the full ingredients list? People can only help when given more information

    If you are getting a precipitate in your formula, you have a stability problem.
