I go this as a sample in my Birchbox. The sample was adequate for several applications. I loved the feel of this going on, and how much a small amount could cover. I have combination/oily skin, however, and the sample was for normal.dry/very dry skin, so I was only able to use it as a special treatment once or twice a week. Any more and I was breaking out.
Would probably need to use longer to see more results. But it worked pretty well on my skin which is usually fairly dry and has dark spots.
My secret weapon
When I use this as a serum before my moisturizer my skin looks dewy and fresh all day. No joke!! That's what this product does.
I love this product. I've reordered several times and will continue. I've noticed lightening of dark spots on my face. My skin is normal/oily and I've had no issue...especially in the Winter months.
A decent sized sample and very lightweight and easy to use. Has a nice touch-feel as well and doesn't leave your skin sticky before bed.
