I bought this essence as a potential replacement for my Missha first treatment essence.While it is nice and light on the face and moisturizing if you layer it, I find that I prefer Missha over Tosowoong. It is not a huge difference and Tosowoong is more affordable, but for some reason my skin looks and feels nicer with Missha. While I would still recommend this product, Missha remains my all time favorite.
