Have used this product several times over the years, it works well to lighten sun related ``freckles``. Must use sunscreen or freckles will come right back.
Cons: Can only use at night.

This product is the freshest Vitamin C Serum (full of antioxidents) I have ever found. It is clear, which means it has not been exposed to too many elements prior to being bottled. It greatly reduced any pigment problems I had, (like brown spots) and also helped greatly in reducing wrinkles.
Pros: A little goes a long way. It is best to use it as any other serum: on a freshly washed face(warm water), under your favorite lotion. My skin felt so soft - I saw results in just a few days! Not even a month, and great changes have been made!
Cons: There was nothing I did not like about this product. I would suggest it being used in conjunction with the OBAGI night, day or both exfoliating creams; if not, under your favorite cream. (Best results at night!)
