good

I love these products

Fast shipping

Web service was smooth and I had no issues with delivery as well

You guys always deliver my products intact and in good condition

Received my package very quickly and when I opened my package I saw an unexpected free acne kit because I know I didn’t spend the amount that it said online to get a free gift. I really appreciated that!!

This company really raises the bar when it comes to their products and customer service!

I have no complaints with this company, very professional, fast to respond (my 1ST time ordering my order got lost in the mail, no fault to COSRX) but they respond fast and ready to right a new customer. They're products are amazing, receiving seems slow but that's just me impatiently waiting for the greatness.

Products arrive within just days! I really like this line.

Super sweet customer service, love this brand!

I was not expecting this to work as well as it did. It brings a glow to my face while also helping fade any acne scars I had. I’ve only used this for two weeks and it has quickly become the product I grab before anything else. It has no smell, so that’s appreciated.

Amazing company! Fast shipping and always including free samples!

Great service

COSRX is awesome for providing quality products.

Love this brand

Amazing😍

Always good. I do wonder why Walmart is selling your products for less and also Amazon. Amazon does not require a shipping charge and I could pick up at Walmart. Both are also quicker at shipping so I also get the products quicker. I wish you did not charge shipping as I would order more frequently and try different products. I hate to feel I am putting out so much money on myself and also do not like having to wait until I have spent enough to get free shipping. When I have spent enough to get free shipping, I feel guilty spending this money on myself and my face. Please start offering free shipping! I would prefer to make sure the products I get are original but am assured by your website that Amazon products sold by you are original. Therefore, unless I am purchasing enough for free shipping, I will most likely order via Amazon to save shipping charges and sometimes find better deals.

Great service. The ups shipping is fast and on time. My forehead often has breakouts,I received AC sample for treating ance, which seems great.

Love this product and will never use anything else!

Excellent service!
