Product Review (submitted on April 28, 2010):
I used this serum for 3 nights, only once a day instead of 2. By the next day or so, the area that I was treating, became even darker and more defined. I have stopped using the serum until I hear about others experience or comments. Thanks for any response. Editor's Note: We are sorry to hear you were disappointed with the Lightening Serum, Nora. Please contact us at firstname.lastname@example.org or 800-903-4321 and we will help you find a product better suited for your skin type and hyperpigmentation concerns. Sincerely, the glo team
