Hello, because the formula has many elements. therefore difficult to predict The team speculates that it might be caused by 4MSK or Tranexamic Acid , I recommend you to remove these 2 items from the formula, it should reduce the risk of discoloration.

It will be made for sale. This formula is the only formula that after mixing for a while will change color. If I change the ingredients from Tranexamic Acid and 4MSK is another ingredient that provides good melasma treatment effect. Can the team be able to help you?
