Neulii - agathagaribe review for Niacinamide 10 Brightening Ampoule

I have tested Neulii's niacinamide for over 25 days. The serum is full-bodied and absorbs quickly. What drew a lot of attention in the product was the shine and a "protective" layer it left on my skin. My skin texture felt much better and the skin glowed beautifully. It's a wonderful product.
