I just got this product and I need a little guidance. So, I really really really don't want to lighten my skin, I just want to get rid of dark spots (which is almost all over my cheeks, and side chin area), as well as hyperpigmentation and uneven skin(around my mouth area, side chin, neck). So, how often should I be using it, like twice a day, once a day or a couple times a week? How long should I leave it on? And should I use it as a spot treatment(well not really spot since there are large areas) or just apply it all over my face?
Does this really work for hyperpigmentation ?
