The most effective treatment for pigmentation with 100% guaranteed results is Obagi C-Rx. The only reason why Obagi is so amazing and why it is different from any other pigmentation treatments available is that it is the only system which can go as deep as down to the bottom of your epidermis where the melaniyn membrane producing melanocytes is located (all other systems available at the market right now, including chemical peels or laser resurfacing, can go as deep as to the middle of your epidermis only (which is still better than nothing) but if your problem starts down from the bottom of epidermis, like it seems in your case, you will get spots back pretty quickly. When you go outside, the melanocytes travel to the surface of your skin to protect you from the uv radiation (not just when it is sunny but even when it rains), and when the melanin membrane produces the melanocytes enevenly (in groups) instead of distributing them evenly, they shoot to the skin surface to protect you but they shoot in groups giving you pigmentation and fracles. Have a look at before and after photos and do a bit of homework about Obagi C-Rx - we put a lot of useful information about it on http://www.bodysilk.co.uk
