Direction for Use Add small amount to your favorite serum, lotion or cream up to 5%. It will dissolve in it slowly. For maximum results, apply B3 vitamins in the morning and evening. To reduce irritation from your retinoid, use it in conjunction with niacinamide "Mix them together in the palm of your hand before applying-they won't inactivate each other," says Baumann. Besides decreasing side effects, the combo produces superior anti-aging benefits. Keep it in dry, cool and dark places.
