Incompatibility of Zinc PCA and Hi-EGCG in Formulation

Question

What happens when Zinc PCA and Hi-EGCG are mixed in the same formula? Will there be precipitation or loss of effectiveness? Is it possible to use them in separate formulas? And for oil control, is Pure-EGCG more effective than Hi-EGCG?

MySkinRecipes Expert · Accepted Answer

Based on the information provided: When Zinc PCA and Hi-EGCG™ are combined in the same formula, it will cause precipitation, and Zinc PCA will lose its effectiveness. Using them in separate formulas applied sequentially (e.g., applying the Hi-EGCG™ formula first, waiting, then applying the Zinc PCA formula) is possible and an appropriate method. If your goal is to reduce/control skin oiliness, the staff recommends considering Pure-EGCG instead of Hi-EGCG™, as it may be more effective for this purpose.
