I want to know that Safe-B3 ™ ( Vitamin B3, Niacinamide , Switzerland) GlucoBright™Tranexamic Acid can be mixed into lotion. right? The ingredients must be dissolved in น้ำกลั่น before pouring it into the lotion. Or do you put the ingredients in the lotion at all? do not dissolve in น้ำกลั่น will the performance deteriorate? Please advise
If the original lotion base There is already water as an element. can be filled in And blended or stirred well, most of the time, there will be no problem.
In this regard, check the usage rate. and do not use more than the specified rate
