I struggle a lot with hyper pigmentation from acne scarring, so I've been looking everywhere for a product to help those fade fast. This was totally it! Its smells very lemon-y, I believe its because of the vitamin C in it, I love it! Makes my spots disappear almost completely in about a week and a half, which is a lot faster than if I just let them go by themselves. The package is also super sleek and high quality compared to other ampoule-like products I have used before. I will definitely repurchase this, and in the bigger bottle!!
