This is the first concentrated 10% niacinamide formula blended with natural calming and superior hydrating ingredients to address the frustrating combination of enlarged pores plus visible signs of aging, such as uneven skin tone, lack of radiance, rough surface skin texture, redness and dryness. Niacinamide is a form of vitamin B3, a powerful skin-restoring ingredient, which research has proven can reduce the appearance of enlarged pores, uneven skin tone, wrinkles and dry skin by supporting skin's natural collagen production. The water-like texture of 10% Niacinamide Booster is designed to dramatically enhance your skin's tone and texture while also providing soothing agents like licorice root extract to promote visibly calm skin. Antioxidants, like ubiquinone and carnosine, and skin-replenishing ingredients, like phospholipids and sodium hyaluronate, make this product a multi-tasking must-have solution for all skin types, whether used alone or mixed into your favorite serum or moisturizer. This is a game-changer for those with enlarged pores from previous blemishes and generally uneven skin tone and texture. All Paula's Choice products are 100% fragrance free, clinically proven to be non-irritating, and never tested on animals. PACKAGING MAY VARY.
