I believe I gave it a good college try
I bought this from Costco 18 mo ago.  I am posting here as they no longer carry it and I wanted to leave a review.  I have been using this product every day on my face for 18 months, and I am throwing it out today.  It has not lightened any of my hyperpigmentation spots.  I believe I gave it a good college try, but this product is worthless.
