I saw on Instagram that this product is effective against dark circles, so I bought it along with the concealer, pencil, and brush that someone else also uses. I looked it up and found out that she's been using it for two years now, and it hasn't really reduced my dark circles at all, just a slight depression. On Instagram, it really did hide my dark circles in an instant, but it didn't cover them that well on me. However, I feel like it covers my dark circles better than ever before. The combination of concealer, pencil, and brush is great, but I think this powder is the best. Even though it's a powder, it has a concealer effect, so I sometimes use it alone when I want a light coverage. I also use it on the dullness around my nose. It's not drying and stays beautiful even after a long time.
