Zinc PCA is a complex of Zinc and L-PCA boasting dual benefits for oily, blemish-prone skin. Zinc is a trace element that directly acts on high levels of androgenic hormones (testosterone and DHEA) in the skin, helping to block the overproduction of sebum to rebalance these levels that go into overdrive when androgens are too high. L-pyrrolidine carboxylic acid (PCA) is an amino acid that is naturally occuring in the skin’s barrier which is an essential part of skin hydration and proper barrier function.
