    I made facial serum, results are good my question is do i must need to check ph of this serum?

    My formula based on

    Distilled water
    Cocumber extract
    Hyaluronic acid
    Niacinamide
    1,3 propanidial 
    Glycrin
    Preservative is liquid germal plus
    Formula is going very well with more using for last 10 months but i am confused about ph level it is must to check the level of its ph?

    You should check it to ensure that it’s within the compatibility range of your ingredients, and also to monitor for changes of pH over time.
