The main difference between the Power Grip Primer (green face primer) and the Power Grip Primer with Niacinamide (pink face primer) lies in their formulations and specific benefits. Power Grip Primer is our original formula, focused on creating a tacky base for longer-lasting makeup and contains hydrating ingredients such as hyaluronic acid. Power Grip Primer with Niacinamide retains the original gripping properties of our OG Power Grip Primer, but is also formulated with Niacinamide which may help to improve the skin appearance and add moisture.
