They Work
My younger sister put me on to this brand. I am in my mid 40s and my skin changed and I didn't know what to do. Everything I tried irritated it or simply didn't work. My eye area had become dark, dry and cracked. I have always had a sensitivity to retinol and all the none retinol products weren't helping. Finally my sister put me on to I Know. I am sooooo happy she did! I got this set plus the Eyes Matter and it works! They work! I use the Eyes Matter with a base oil around my eyes and my eyes have visibly lightened and aren't burning and cracking due to dryness any more. The rest of my skin also looks amazing and with daily use, this set lasted me at least 3 months if not longer. My only negative is that the packaging isn't see through so I cannot tell when I'm about to run out. I don't want to run out!

I started using the products the 1st day of January so no results as of now. No breakouts which is awesome!!!
