Unique Texture, Amazing Results — Now One of My Favorites!
This serum definitely has a texture similar to snail mucin, so it took me a few tries to get used to — but I’m so glad I stuck with it because the results are incredible. Once it absorbs, my skin feels deeply hydrated, smoother, and so much more plump.
The rice and ceramide formula really strengthens the skin barrier, and I’ve noticed my complexion looking brighter and healthier overall. It layers beautifully under moisturizer and doesn’t leave any sticky residue once it settles in.
If you’re looking for a hydrating, brightening serum and don’t mind a unique texture, this one is absolutely worth it. It grew on me fast and is now a staple in my routine!

Great products
Helps with skin irritation does not leave a crazy residue. It is effective and it's an easy application! so the valuable for your money . They could definitely charge a little less, though. But all around great products by ANUA

Glass skin in a bottle
I read a review here saying this product was glass skin in a bottle before purchasing myself, and to be fair, I didn’t get it because of that particular effect, but the way my skin has changed since I started using it is just amazing. I’ve been using this for several months now along with the toner and moisturizer from the same line. This is hydrating, leaves a beautiful glow on the skin, wears great under makeup, and I’ve noticed more and more people commenting on how nice and healthy my skin looks since I started using it. I am currently going through a hormonal acne flare up, and this helps my skin feel calm and does not break me out at all.

Hydrating and NOT Sticky!!
As someone who has VERY dry and sensitive skin, I love this product. It gives me an extra layer of protection during the cold and windy days, so I don’t have to worry about my skin burning or peeling the next day. It’s pretty lightweight, and really only feels like you are putting on water almost. It gives your skin a subtle glow too which is nice, and has no scent (which is perfect for sensitivity). It works super well and makes your skin looks plump. The only reason I’m docking a star is because a few times I’ve used this I have had issues with my makeup (especially around my eyes) separating or peeling off. I’m not sure if this is happening because of the reaction with this product and my sunscreen or what, so take that with what you will!

Great Skin Product
I’m absolutely impressed with the ANUA Rice Ceramide 7 Hydrating Barrier Serum! This fragrance-free Korean skincare serum combines the power of rice, hyaluronic acid, and niacinamide to brighten, hydrate, and strengthen my skin barrier. After using it regularly, my complexion looks noticeably more radiant and plump — that coveted glass skin glow is definitely real!
The serum is lightweight and non-comedogenic, making it perfect for daily use without clogging pores or causing irritation. It complements my routine perfectly after cleansing with the Anua Heartleaf Pore Control Cleansing Oil and using the 3-in-1 Jade Roller and Gua Sha Facial Kit to boost absorption and circulation. Together, these products have transformed my skin, reducing wrinkles, controlling pores, and keeping my skin hydrated and fresh.
If you want a gentle yet effective serum that brightens and deeply hydrates while supporting your skin’s natural barrier, this is a must-have!
