  AHA acids

  Posted by Deborav58 on May 2, 2022 at 9:02 pm

  Hello, I’m trying to make a aha peel with Hyaluronic acid.  I have 70% lactic acid and 99% glycolic acid powder. My question is do I have to dilute the acids first or can I add them as is. I want 10% lactic acid and 4% glycolic acid?

  You dilute them by adding them into the water. 
  So you are going to use 14.3% of lactic acid to get 10% solution and 4.05% Glycolic acid to get 4% solution.

  10/0.7=14.3

  4/0.99=4.05

  Been a while since school, eh? :smiley:
