Zinc PCA Benefits
● Zinc PCA can reduce skin oil secretion
Zinc PCA controls acne and reduces sebum (a sebum regulator) produced by oily skin and helps maintain skin moisture. Zinc actively reduces inflammation and also has antibacterial properties.

● Zinc PCA has effect on acne and acne
Zinc PCA is thought to have an important role in the biochemistry of the skin. Thus, Zinc PCA was shown to be a synergistic effect of two elements, namely zinc and L-PCA. Zinc helps control acne while L-PCA is responsible for strengthening the skin barrier. Zinc ions have the property to be used in the form of zinc salt, Zinc PCA, which can be used in skin care products. Zinc ions are soluble, making it easy to apply to the skin. Thanks to NMF (Natural Moisturizing Factor), it binds water and reduces moisture loss.
● Zinc PCA can prevent skin aging
Zinc PCA has a preventive effect on skin aging. This is because it acts as an antioxidant that counteracts the degrading effects of UV radiation on collagen.

Products Applications
It is one of the most assorted and best ingredients in the skincare industry. It has a gentle effect on the skin, especially for sensitive types, and is therefore one of the few key ingredients in skin care products. Zinc PCA can be used in serums and moisturizers in various skin care products. Zinc PCA is considered a generalist in the skincare world.
