I've been using for 3 weeks. I have really really bad dark circles, from my dad, so till this day, I tried many products with no results, my dad even did a laser treatment that never gave him results. This product is amazing, I'm not saying that it clear the dark circles because that would be a miracle but since I started I can see improvement. No more puffiness and the dark circle is much more clear now. I don't really sleep or eat right so there is no way I can get rid of the dark circles all gone, but this product is helping a lot and I'll keep using it until is done.
