Oxido-N combines water-based multitasking bioactive ingredients. Niacinamide with Zinc PCA. It supports natural body processes to reduce enlarged pores dramatically, dullness & balance uneven skin tone & texture. Niacinamide also serves as a helpful element for acne skin since it aids in lowering face sebum production. Raising the level of ceramides with free fatty acids in the skin barrier helps rebuild a healthy skin barrier. Zinc PCA is a zinc salt that actively binds moisture in the skin & lessens transepidermal water loss. It also reduces redness & sebum & collagen production, thus promoting skin healing in general.
