    Hi

    I made an alpha arbutin serum with these ingredients:

    Alpha arbutin 2%

    Glycerin 3%

    Propylene glycol 3%

    Sodium hyaluronate 0.5%

    Phenoxyethanol 1%

    It changed its color and turned brown.. what should i add to make it stable

    Add a little bit of lactic acid to steady the pH at 5.0 - 6.0 and a bit of mannitol to inhibit redox reactions with light, oxidizers.
