"I absolutely love this stuff! A little goes a long way. The essence and Finish makes my skin very clear and glowy. I don’t need to wear foundation for coverage anymore. I highly recommend it and I will keep it in stock. It actually firmed up my skin on my forehead."
"This is a staple product for me. A great addition to any of my skincare routines because it doesn’t conflict with any active products that I use. Great layer into my skincare routine and well priced. Has vastly increased moisture in my face and other areas I use it."
"Holy grail. Need it everyday. Was the first product that got me into cosrx and I've been in love ever since. This is the OG and I reccomend it to anyone like me who knows nothing about skincare to get a good foot in the door. If I had to pick one skincare product to only use, this would be it for sure. If you've been not believing the hype, start believing because its like I said. . a holy grail."
"The beauty of a product is amazing. It’s totally hydrating and keeps my skin feeling smooth. This after 2 hours and no make up in the morning and still doing its job"
"One of the big changes I got from this was a shine. It makes your skin shine and feel hydrated and plump. You should wait a minute or two after applying to let it dry. The consistency is a bit slimy but doesn't feel disgusting, but hydrating. It dries without leaving a residue. The biggest benefits for me were the shine and hydration without clogging pores."
"I’ve been using this snail mucin consistently for the past 5 years. It’s really transformed my skin and helped with brightness, plumpness, and overall look! I follow a consistent routine and this is always the first product I start with. I’ve never partner with a brand for this product, just a regular person who loves it lol. meal"
"I’ve been using several Cosrx products since a friend of mine introduced me to this lovely product. I’ve added several since I started about 2 months ago. I love layering the Products according to Cosrx web page and am so happy with my skin. I have sensitive skin in addition to it being dry and your products work for me. The only two I have issues with is the low dose Retinol and the Vit C. But if I use it like Cosrx recommends I am able to use it. I’m happy and will continue to order from Cosrx❣️ k. Hunt- Texas"
"For all of us who are confused about if they’re skin is actually dry, oily or sensitive or all of the above?! I recommend this lol can’t go back to using nothing else actually."
