Zinc Palmitoyl Nonapeptide-14 is a lipidated copper/zinc-bound peptide combination used in cosmetic formulations primarily to help regulate sebum production and reduce the appearance of enlarged pores and oily skin. It is marketed for blemish-prone and oily skin types, often paired with other actives targeting excess oiliness.
