Zinc Oxide will work on the skin.
Zinc PCA Can be dissolved and absorbed into the skin, so it has the effect of disinfecting, reducing it and healing acne wounds. However,
Zinc PCA does not have UVA/UVB protection because it is absorbed into the skin. not coated on the skin The formula can use both items together.
