Zinc is a mineral which in this form regulates sebum production, reduces redness and irritation and so helps in treating skin with acne. Recent research indicates the fantastic role of zinc in preventing premature aging of the skin, as well as in restricting the development of pathogenic microorganisms on the skin (source: Y. Takino, F. Okura et al 2012 Zinc l-pyrrolidone carboxylate inhibits the UVA-induced production of matrix metalloproteinase-1 by in vitro cultured skin fibroblasts, whereas it enhances their collagen synthesis International Journal of Cosmetic Science, 34:23-28).
Large doses of zinc can sometimes be drying, but zinc PCA (or zinc l-pyrrolidone carboxylate) is an excellent skin moisturiser and does not obstruct the normal function of the dermal barrier. Due to all of the above, zinc PCA is considered an excellent anti-age as well as anti-inflammatory ingredient to add to everyday skincare. Skintegra’s product designed for acne and comedone treatment, Tria Light, contains zinc PCA with the addition of niacinamide and vitamin F.
