This is the mask that made "just sleep in it" a legitimate skincare method. COSRX's Ultimate Nourishing Rice Overnight Spa Mask is a cream-textured overnight treatment built around rice extract and niacinamide — made to soften, brighten, and deeply moisturize while you sleep, without the heaviness of a typical thick mask.
It works as an overnight mask, a 15-minute wash-off treatment, or even a daily moisturizer if your skin runs on the drier side. One product, three ways to use it.
