After standing about six months from the purchase, I tried in parallel using the oil of here and other brands. To review that there is argan oil peculiar smell, because I wanted to make sure how much difference there of. The difference is Rekizen, odorless oil of larenim for me. Until that time you're done from the moment you opened, odorless without even particularly feel the deterioration. Might not be a difference in the efficacy of the oil itself, the smell there is a great difference.
