Sunday Riley Be Nice 10% Niacinamide Serum

Niacinamide is beneficial to oily and dry skin, as it helps to diminish the appearance of stretched pores and regulate the look of visibly shiny, oily skin, while also supporting the skin’s natural moisture barrier, which helps to prevent water loss and dryness. Niacinamide also improves and evens out the signs of blotchy skin tone, caused by post-blemish marks and general surface redness.
