1. astringent effect
Zinc causes enlarged pores to contract and has a sebum-regulating effect. The trace element can thus help to refine your skin texture by drying out minor skin impurities.
2. antiseptic effect
Zinc prevents the development of microbial infections and is therefore ideal for blemished and oily skin.
3. moisturizing effect
PCA protects the skin from drying out, because the active ingredient is characterized by a water-binding property. Your skin is thus supplied with sufficient moisture and the feeling of skin tightness is reduced.

In normal cases, however, there should be nothing to prevent the use of facial products with zinc PCA during pregnancy.
