Authentic product?

I just bought this Iunik sleeping mask off of Amazon because from what I could tell by digging around and reading a bit, Amazon is a legit seller of Iunik products if you are purchasing from the seller CrediThink. I did purchase from that seller, the reviews were good (nothing mentioning anything about fake products being received), and the product came sealed with a code you can scan with an app to verify it’s authenticity. Seems to be a totally legit product and seller to me. There are more Iunik items on my wishlist I’d like to buy soon, so just wondering if others have also purchased Iunik from Amazon and had good experiences and if I should continue buying from there or not. Oh, and I did try out the sleeping mask and loved how my skin looked the next day!
