The name says it all and pretty much what's in it. When I first applied this serum , I instantly thought I messed up. It has the look and feel of a thick oil serum when you first apply it and everyone knows oils go on last. But as I massaged the serum thoroughly all over my face , it fully absorbed like a regular serum. I was quite amazed! My skin felt soft and there was no oily or greasy residue. It's just a thick serum that's packed with antioxidants and skin brightening ingredients. Its a gentle vitamin C serum , I didnt have any skin issues or irritation. After using for several weeks , my complexion looks healthier and more radiant.
