  Making a peel serum

  Posted by Rana_91 on September 15, 2024 at 5:10 pm

  Hi

  Iam making this formula

  10% glycolic acid

  2% salicylic acid

  40% propylene glycol

  3% glycerin

  1% phenoxy ethanol

  0.3% sodium hyaluronate

  I Am dissolving salicylic acid in propylene glycol with heating

  In separate container I’m adding sodium hyaluronate with water until it dissolve.. then i add everything gradually

  Once i try to adjust the ph ( with tri ethanolamine or sodium hydroxide)

  It thickens and form a gel

  What is wrong in this process and how to fix it
