Be careful with Amazon. It's been known to have counterfeit beauty products. I only buy from places that are vetted in the Asian skincare subreddits. I've had good luck with Yesstyle, and I recently placed an order from Yamibuy that went well.y
Etude House actually is a seller on Amazon, so it's one of the few that are legit to buy there.
I think this is the link to the one sold by the official store, but always double check that seller is Etude House Official and fulfilled by Amazon
Yes, I love Etude House Soon Jung 2x Barrier Intensive Cream! Amazon link
