philosophy’s first all-in-one serum features a supercharged formula created to prevent and correct the appearance of multiple skin imperfections at the source. Every drop contains a potent dose of the brand’s exclusive marine extract, botanical extracts, concentrated niacinamide and active vitamin C to help interrupt the lifecycle of dark spots and marks, bisabolol to soothe and neutralize the look of redness and blotchiness and salicylic acid to clear and shrink the appearance of enlarged, darkened pores and refine rough texture. With repeated use over time you’ll notice a reduction in blotchiness, redness, rough texture, acne marks, enlarged pores and dark spots. It also consistently fortifies your skin day after day where it needs it most. How to use: Apply liberally after cleansing and before moisturizer. 1 oz. By philosophy; made in the USA.
