KEY INGREDIENTS Niacinamide (10%): Niacinamide is a multifunctional superstar ingredient that normalizes pore size, reduces acne breakouts, improves the skin's natural protective barrier and reduces hyperpigmentation spots. Zinc PCA: It is a combination of the antibacterial and sebum normalizing Zinc, with the humectant molecule PCA found in the skin, PCA (stands for pyrrolidone carboxylic acid). Zinc PCA encompasses the properties of both ingredients, being a gentle, non-drying ingredient that helps with oily and acne-prone skin.
