I've used bioelements for a while. I am familiar with the packaging and the seal. The seal on this was different than normal. I was just replacing a previous one that had run out also purchased on amazon. The seal was different than any of the numerous ones I've used. As well the texture and smell was different. Oddly I started developing weird dry patches and itchiness. I didn't put this together until I ran out the other day and I was substituting with my other products. The dryness is going away. I just received another jar from a different vendor that was the normal seal. I contacted amazon at the time about what I noticed and they assured me it had to be right. But well...moral of the story if you are familiar with the product trust your instinct and ask for a replacement.
