Zinc PCA is one of the skin's most moisturizing factors. This ingredient decreases redness and irritation as well as helping reduce oiliness.
How to use it
Beginner: Add up to 1 tube to your favorite water-based formula.
Advanced: This ingredient is recommended for use at up to 10% in formulations. This ingredient is best suited for serums, toners, sprays, and other primarily water-based products. For best results, use this ingredient in formulas thickened with gums, like xanthan or sclerotium, but it can also work with polyacrylamide based thickeners. This ingredient should be added during the cool down phase of a formulation with final pH of 4-6.
Zinc PCA can cause precipitation to form or loss of viscosity depending on the formulation being added to. Store in a cool, dark environment for best results.
