White Lightening Serum (1 fl oz.)

I used it for a full month twice a day over my lip hyperpigmentation area. When I recently started pre-menopause my skin pigmentation became dark above my lips, and it was noticeable. I got medium oily skin, with yellow undertones, I burn a little under the sun, but mostly tan easily. After using a generous amount above my lips twice a day for a month, using SPF sunscreen 70, and staying out of the sun, the dark pigmentation still there. On a positive note my face stayed clear from pimples/zits, light weight serum, and absorbs like a normal serum would, easily. Will be trying something else, in the cheaper category...
