I used freckle cream when I started to have chloasma. I don't know what ingredients in it made my skin allergic for two weeks. After that, I dare not use freckle cream again. Later, my colleague introduced me to buy an oo skin freckle product online. After two courses of treatment, the spots disappeared. I couldn't believe it then. I always hear that it will rebound a little, for fear of being happy too early. It's been more than two months now and it hasn't rebounded at all. This is reassuring. This is all my personal experience, I hope I can help you.
