  Ph of facial serum

  Posted by saraahsan on July 29, 2021 at 2:26 pm

  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.
