How it works
An overnight mask is the last layer of the evening, and it earns its place by staying on for hours. This one is oil-forward: sunflower seed oil sits near the front of the list with palm kernel oil behind it, and niacinamide and rice extract are on the same list. It goes over the whole evening routine, in a layer generous enough to feel, and it comes off with water in the morning. Skin that looks dry and dull on waking is the case this answers. Two or three nights a week, or nightly through a cold, dry stretch.
Key benefits
- Sunflower seed oil opens the ingredient list.
- Niacinamide sits in the top five of the list.
- Rice extract, the ingredient behind the name, is on the list.
- Cetearyl olivate and palm-derived emollients round out the overnight cushion.

COSRX Ultimate Nourishing Rice Overnight Spa Mask
Is rice really the main ingredient in this mask, given the name?
Rice extract sits eleventh on the ingredient list, well behind sunflower seed oil in third place and niacinamide in fifth. The formula is genuinely oil-forward rather than rice-forward by ingredient order, even though rice is the name the product is sold under.
Is this mask too heavy for oily or combination skin?
Sunflower seed oil, palm kernel oil, and palm oil all appear in the first half of the list, which makes this a richer, more emollient formula than a typical overnight mask. Oily skin that reacts to heavier oils may prefer to use it only occasionally or on drier areas of the face rather than the full face nightly.
How is niacinamide positioned in this formula?
Niacinamide is fifth on the ingredient list, after the base oils and glycerin but ahead of the majority of the formula's other ingredients. That position indicates a meaningful rather than trace inclusion, working alongside the emollient oils rather than as the formula's sole focus.
Can this be used every night as a regular moisturizer, or is it meant occasionally?
The rich oil-forward base and the overnight spa mask framing suggest this is built for a periodic, more intensive step rather than a nightly moisturizer replacement, though the ingredient list itself contains nothing that would make daily use unsafe. Anyone using it nightly should watch for a heavier feel than they expect from a standard cream and adjust frequency accordingly.
Does this mask contain any fragrance?
No parfum or fragrance ingredient appears anywhere on the list. Any scent would come from the natural oils and extracts themselves, primarily the sunflower seed oil and rice extract, rather than an added fragrance compound.

How to use
- Use the Ultimate Nourishing Rice Overnight Spa Mask as the last step of the evening, over your moisturizer.
- A generous layer over the face and neck, patted rather than rubbed so it sits evenly on the surface.
- Everything else goes on first and nothing goes over it. Rinse or wipe it away in the morning.
- Two or three nights a week. Do not use it on the same night as a peel or an acid; give the skin a plain evening instead.
