Cosmetics Formulation Development

AcnePLEX™ The instructions say not to use with Gel Maker with charge in the mixture. I want to ask (Serum that has been successful) when applied with other serums, for example, the first serum contains ingredients. AcnePLEX™ and then apply the second serum containing Gel Maker can be applied or should I apply at different times?

Hello, if you can use it together But can't mix them together first.

thank you

Ask for more information, in the formula I use AcnePLEX : 5% Pure-Succinic™ 1% Mild Preserved Eco™ 1% I would like to inquire further if I put Pure-Succinic™ 2% (as สารกันเสีย and kill the acne itself) and cut Mild Preserved Eco™ 1% off will cause skin irritation or not? Or should I use the first one and not cut it? Mild Preserved Eco™ Exit Interference Please advise, thank you.

Hello, there should be Mild Preserved Eco 1% regardless of Pure-Succinic or not.
