Honeygem,
read that u have dark eye rings problem. haha, tell me about it! I have the exact problem too, no concealers help, no eye cream helped either. I have spent so much on eye creams that I have given up hope, my most ex investment so far was the eye cream by Clea de pau that cost me $170 back then!
Anyway, recently tried the eye mask by Shisedo...it helped me...put it on twice a week and for the following morning at least, I looked much awake and lighter rings. ;p I can't rem how much they are selling in spore, i always get mine in hongkong, it's cheaper I rem, ard S$40 after conversion. It comes in a packet of 10 masks (pairs) in one box. So if you use it weekly, can lasts you up to 2.5mths.
