It was popular so I was intrigued and bought it. It didn't irritate my sensitive skin, and I didn't mind the tingling sensation on my face after applying it, but when I applied another moisturizer afterwards, it tingled everywhere I touched, so I had to be careful, and even after washing my face the next day, I still felt the tingling sensation around my neck and other areas during the day, which I hated (lol). The bottle is also vacuum sealed, which is good for hygiene, but as the contents decrease, the center of gravity rises and it tends to tip over easily, which is annoying, so I think I'll only use it when I receive a sample in the future and not buy the full product.
