This is great! You really only need two drops to create a thin film on the face and neck. I followed it up with my moisturizer and it's not greasy at all for me. The polyglutamic acid really helps with hydration. My skin feels plumper. After using about 3/4 of the bottle, I didnt notice a major difference in my dark spots / hyperpigmentation but I will 100% repurchase for the hydration benefits.
