The FACES OF FEY niacinamide booster contains as much as 10% niacinamide. The active ingredient is a form of vitamin B3 and it reduces skin damage caused by free radicals and causes the skin to age. It also works against enlarged pores, an uneven complexion and fine lines. Niacinamide is even more effective when combined with other active ingredients. That is why our niacinamide booster also contains beetroot extract. This antioxidant protects the skin from free radicals, moisturizes and has an anti-inflammatory effect. The boosters have been specially developed for use with ultrasound and microneedling and are also ideal as a 30-day intensive treatment when used individually.
