I used a full container of this, applying it every day. It only lasted about 3 months. It lightened my skin unfortunately every place but the freckles and brown spots and I am fair to begin with. I really wanted to give this product a big chance because I had read good things about it. So, I then bought the daytime formula because I was tired of the night formula which comes in a jar with a spatula. While the application for the daytime product was easier, neither product helped me.
