Cosmetics Formulation Development

I want a recipe Pro-Cysteine is also included.

Hello Pro-Cysteine is soluble in water, so it can be easily found in any formulation, whether it is gel, cream. or essence But be careful with the pH, if used at a large rate, plus the formula has few other components, it can cause a very low pH of the formula. It is recommended to use it at a low rate. for easy mixing And there is no need to adjust the pH of the formula.

thank you
