This is to let you know that I am so pleased! For some time I had been getting more and more brown pigmentation in the middle of my cheeks, despite wearing sunblock. I had tried fading the spots with various skin lightening creams. Nothing really worked though, even after giving them plenty of time. When I bought the green light, I also bought a bottle of your jellen hyaluronic acid serum to go with it. I used the green light and serum faithfully, twice a day as suggested, and after one month, the spots had faded significantly. You cannot imagine how relieved I was! At this point in time, the spots are much lighter and I use much less cover-up now.
