Even skin tone
[This review was collected as part of a promotion.] I have noticed a different in my skin since using this product. I have noticed the brightening effects. My skin tone is more even with less dark spots. While I do not store the product in the fridge one it is opened, I store my unopened products in the fridge. I made the mistake of leaving an unopened one in a cabinet. It evaporated within 2 months.
