I really like both products. I usually have purple skin around my eyes but it's noticeably brighter when I use the eye cream. I didn't notice the eye cream lightening my sun spots, but I definitely noticed the serum lightening my sun spots in my face. At first use, the serum stung my skin, but my skin got used to it really quickly. I wish the serum existed in a smaller size. It definitely oxidizes before I finish it, even with daily use. It also has a notable smell, which lingers for a while.
