Bests & Worsts Reviews from Amazon

I purchased this after first trying the 9wishes Rice Foaming Cleanser from Costco in their Case full of Seoul Korean Beauty product kit. I loved the product, the fresh scent and very mild scrub when I used the product from Costco. I wanted to buy a second tube of the cleanser and could not find it anywhere except on Amazon. The product I received from Amazon has an expiration date on the tube of 2019, the tube from Costco is 2020. They are clearly from different lots/batches. It is impossible for me to know one hundred percent, but I do not believe the product I ordered from Amazon is authentic as there are significant differences. The product in the tube from Costco is a nice, even clear white color, very smooth on my face (non-abrasive at all) and has a nice soft smell. The product in the tube from Amazon is more of a dirty light beige color, has a significant abrasive feel and an almost soured milk smell. I have used the tube from Amazon about four times, and will be requesting a refund and return of the product. I love to shop on Amazon, but this is definitely not worth it. The photos are comparing both tubes. The tube on the right is from Costco, the left Amazon. You can see the main difference in packaging on the back side is the information about the company and bottle type. I do not speak/read Korean, but you can tell the difference. You can also see the difference in the color of the product in the photos.
