I bought this at my local Asian grocery store and have had it about 4 months now. I always shake the bottle before applying. For a few days it seems to be foaming like soap where as normally it only bubbles a little bit. Is it going bad? I hear people can use up a bottle of this by 3 – 4 months but I expect the bottle to last me 3 more months (6 – 7 months per bottle). Am I using it too slowly?
