I have done 彩光 for 5 times last year. The result was pretty good. It has lightened my ance spots and my face was much whiter than before. However, i also keep on having acne every now and then and thus have new spots. I just wonder if I should do the 彩光 again for another 5 times (as the price for 5 times package seem cheaper). Anybody has kept on doing 彩光 a few times every year?
