This is the Hanyul Moonlight Yuja C™ Serum 50ml, which I purchased with my own money and can verify. It has a very refreshing yuja scent. ^^ After cleansing and wiping my face with my basic toner, I apply the serum gently, letting it absorb. It doesn't provide an immediate brightening effect, but it absorbs moisturizingly without feeling cakey. After using it consistently, I have noticed a significant improvement in my blemishes, and my complexion has become clearer. ^^ I purchased this at Olive Young.
