AHA in Soap Based Face Wash
Can I add salicylic acid and glycolic acid in soap based face wash? what precaution should be taken in terms of pH? will it works or stable at pH 8-9 since KOH is being added?

No, the two acids won’t work at that pH, they turn into their salt form and be nothing more than pixie dust, great for claims but nothing more.

Are you saying that “do not use these two acids”?
Can I use any one of them? -
At pH 8 - 9, acids become ineffective salts. So, you can’t use either if you want them to actually do anything.
