Customer Reviews
Good products, shipping could improve
I ordered the COSRX Advanced Snail 96 Mucin Power Essence and the Laneige Lip Sleeping Mask. Both products were authentic and exactly as expected, which is great. The prices were competitive, especially for these popular items. Shipping took about 12 days to reach me in California, which felt a bit long. The packaging was secure though, no leaks or damage. Customer service was responsive when I inquired about tracking, so that was a plus. I'd likely shop here again for the product selection, but I hope shipping times get a little faster.
Love my new toner!
Just received my Some By Mi AHA BHA PHA 30 Days Miracle Toner and I love it! It arrived quicker than I thought, only 8 days! The product feels amazing on my skin, just as I'd hoped. Will definitely be getting more stuff from here soon.
Reliable for K-Beauty staples
This was my third order from Coscosmos, and I got the Beauty of Joseon Relief Sun Rice Probiotics. As usual, it arrived well-packaged and the product is fresh. I appreciate the consistency; I know what to expect. My previous orders for Innisfree serum and Missha ampoule also went smoothly. Shipping is always within the timeframe they estimate, took about 10 days this time. It's why I keep coming back for my K-Beauty essentials.

Can I use my PayPal on coscosmos, or is it just credit cards?
can i stack a first-order discount with a free shipping code if they're both active?
I'm looking at their wholesale options, does anyone know how much of a discount you actually get for buying in bulk?
how does coscosmos compare to yesstyle? i usually buy from yesstyle but curious about other options.
Do they ever have big sales, like black friday or something? waiting for a good deal on some snail mucin.
