The Bottom Line. The Ordinary Niacinamide 10% +Zinc 1% serum contains Zinc PCA and niacinamide, which can provide anti-inflammatory, brightening, and hydration benefits to the skin. This makes it a suitable product choice for those looking to keep wrinkles, discoloration, and oiliness at bay. Take The Ordinary Niacinamide as an example. This water-based, oil-free serum is a "high-strength vitamin and mineral blemish formula.". It contains 10% niacinamide and 1% zinc. The product recommends a twice-a-day application (once in the morning and then again at night) for best results. This serum comes in a clear, fragrance-free gel that is slightly thicker than water and is dispensed with a dropper from a frosted glass bottle. The brand states that this serum is: While this serum is marketed to reduce the look of blemishes, The Ordinary doesn't claim that the niacinamide and zinc mixture will cure acne. The TO Niacinamide is a little wonky in terms of formula wise, as the gum can cause pilling and so can the zinc if one of the product in your routine has a synthetic thickener. The HA is quite a high percentage, so it can also cause pilling as it is a film former. The effect would be worse when 2 of them are combined. Combining niacinamide's oil-reducing prowess with salicylic acid's ability to dissolve excess oil is a great way to help keep pores clear and breakouts at bay—you'll find it in a number of the best face washes for oily skin . Niacinamide's anti-inflammatory and skin barrier-strengthening effects also make it a good option to pair with alpha ihl692.
