  Kojic acid , propylene glycol vs lotion

  Posted by Cletus on May 31, 2018 at 1:06 pm

  What can add to lotion containing kojic acid so that it will stop it from changing the normal lotion color to brown color?

  Again, still inside the same lotion, I noticed that propylene glycol dissolves some of my raw materials inside lotion, does propylene glycol affect the effectiveness of the active ingredient in the solution? -
