The Paula's Choice 10% Niacinamide Booster is a highly concentrated, lightweight serum designed to address multiple skin concerns, including enlarged pores, uneven skin tone, and a dull complexion. Its potent 10% niacinamide formula works to visibly refine pore size, improve skin texture, and brighten the overall appearance of the face. It is gentle enough to be used daily and can be mixed with your favorite moisturizer or serum for enhanced results. To use, dispense a few drops into the palm of your hand and apply to the face and neck after cleansing and toning, or mix it directly into your daily moisturizer. Key benefits include a significant reduction in the appearance of pores, improved skin brightness and clarity, and a smoother, more even-toned skin surface.
