This product is amazing, and I may have to resign as a consultant for a recently number one ranked skin care company in the world...although I love certain products from all of the kits I sell, there is aggravation over the products not being properly measured for daily use. Or, having to mix match kits to get the desired outcome in your skin. You'll run out of one portion before the other, NOT SO with Saranghae!!! The quality and quantity is equal! My skin is unpredictable, but since using Saranghae, it's completely balanced! How? I don't know, it just works!
