Bests & Worsts Reviews from Amazon

I purchased this item few month ago and it was great. So I decided to buy it again and I had chance to compare the old and the new onw. Could you see the color difference? Also, the product smell changed. not light and little damp. (the thing on the spoon is the old one. and I added lot numbers to whom want compare theirs with mine. sorry that pic was too light). So I emailed the company but they did not answer it. Product quality problem? That's okay. It alwayes happens. Or the ratio of ingredients could be changed. That is okay, too. But not answering to the customer? It goes to bad ending. I had great time with this product but that's it. I will not buy this again until they answer what is going on and why this happen.
