I started using the COSRX Ultimate Nourishing Rice Overnight Spa Mask in early March this year, right around the time I was focusing on repairing my skin barrier.
For many months before picking this up, my skin was super dry, tight, sensitive, and just not feeling like itself, and I knew I needed something deeply hydrating but gentle.
I’ve always had this sense that my skin thrives with ingredients like rice and oats, so when I saw this mask, it felt like the right fit.
Also, I trust COSRX. I’ve used a lot of their products and they’ve consistently worked for my skin. This felt like a safe choice. And spoiler—I really loved it!
To be honest, face masks are hit or miss for me. Clay masks especially felt too drying for me, while sheet masks were too messy. I didn’t notice much of a difference afterwards, either. I think I was using them just because everyone else was, not because my skin actually needed them.
This overnight mask changed that. It felt more purposeful, like a final step that sealed in the good stuff.
Packaging & First Impressions
Let’s talk about the packaging first. It comes in a soft, easy-to-squeeze tube, which I love! No dipping fingers into jars, and I can apply it directly to my skin. No mess at all.
The formula is creamy white but not greasy, more like a rich moisturiser than a traditional mask. But it’s not heavy on your skin.

Ingredients Breakdown
The star here is rice extract (68.9%), known for its ability to hydrate, brighten, and support the skin barrier. This fragrance-free overnight mask also contains niacinamide to help even out skin tone and sunflower seed oil to nourish and protect.

It’s generally well tolerated, but as with any product, patch test first, especially if you’re sensitive to niacinamide or occlusive textures.
My Experience

I used this every night, applying it after moisturiser as the final step. It’s lightweight and the next morning, my skin always looked softer and smoother.
On retinol nights or after exfoliating, it was especially helpful, it gave that calm, cushiony finish my skin needed.
Like I said, I know some people use it as part of their morning routine. I haven’t tried that yet, but honestly, it’s light enough that it probably works well if your skin’s feeling dry or tight.
I’ve tried the Laneige Water Sleeping Mask before, and to be honest, I didn’t see any major changes with it. It felt nice but didn’t do much for my skin. This one from COSRX? It felt like it actually helped.
That said, while it worked really well for me, I didn’t find it deeply hydrating enough on its own during my most dehydrated skin days. It’s nourishing, yes, but for my skin at the time, I still needed to layer an occlusive on top to fully seal everything in.
Now that my barrier is in a better place, I use this mainly on retinol nights or when I want a quiet evening to myself. And in that context, it’s perfect!
As many would agree, the texture is creamy but lightweight, more like a silky moisturiser than a heavy mask. It spreads easily and sinks into the skin without leaving a greasy layer. It does leave a slightly dewy finish, but it doesn’t feel sticky.
I think this mask is suitable for those who have dry or dehydrated skin, or if your skin tends to be sensitive and easily reactive. It’s especially helpful on post-retinol or exfoliation nights when your barrier needs extra support.
If you’re in the middle of a skin barrier repair routine, or just want a no-fuss overnight treatment that adds comfort without complication, this fits in beautifully.
That said, it might not be the best match if you don’t like dewy finishes or if your skin is very oily and doesn’t do well with richer creams.
Pros and Cons

This is the kind of product that’s easy to underestimate. It’s not flashy, it’s not trending, but it quietly does the job night after night.
For someone like me who’s never been a “face mask” person, this made me get it.
I’ll definitely repurchase it. It’s the kind of product I keep reaching for without overthinking. And sometimes, those end up being the ones your skin is most grateful for.

Thinking of trying it? If your skin’s been feeling tired, tight, or just needs a little extra care, this might be worth adding to your routine.
