A high-strength vitamin and mineral blemish formula with 10 percent pure niacinamide and one percent zinc PCA. Niacinamide (vitamin B3) reduces the appearance of skin blemishes and congestion. A high 10 percent concentration of this vitamin is supported in the formula by zinc PCA to balance visible aspects of sebum activity. This serum helps regulate excess oil, reducing shine and visibly refining pores. Over time, skin appears visibly clearer, more balanced and radiant with every drop, ideal for oily or blemish-prone complexions.
