COSRX Ultimate Nourishing Rice Overnight Spa Mask is an overnight leave-on mask that uses 68% rice extract and 2% niacinamide to deeply hydrate, calm, and visibly brighten skin by morning.

This lightweight yet rich sleeping mask blends traditional rice extract with modern actives to nourish skin while you sleep. Designed for nightly use, the formula focuses on restoring moisture, smoothing texture and supporting a more even-looking tone without heavy residue. It’s free from parabens, sulfates, phthalates and is cruelty-free, reflecting COSRX’s clean-beauty approach.

How does this rice overnight mask work while I sleep?

The mask creates a hydrating veil that helps prevent overnight moisture loss and supports natural skin-repair processes. Rice extract supplies gentle humectant and calming properties, while niacinamide works to promote radiance and refine the look of skin texture.

• 68% rice extract provides continuous hydration and comfort.
• 2% niacinamide helps even tone and improve surface smoothness.
• Leave-on formula absorbs without heavy stickiness, suitable for nighttime routines.

Will this mask work for sensitive or reactive skin?

The recipe avoids common irritants like fragrances, parabens and sulfates and is dermatologist-tested, making it suitable for many sensitive skin types. As always, patch-testing a small area first helps confirm compatibility with your skin.

• Hypoallergenic and free from harsh chemical irritants.
• Gentle rice extract soothes redness and discomfort.
• Designed for minimal irritation when used as directed overnight.

How should I use the COSRX rice spa mask for best results?

Apply as the final step of your evening routine, spreading a generous, even layer over cleansed skin and leaving it on overnight. Rinse or wash off in the morning, then follow with your usual daytime products and sunscreen.

• Use 2–3 times weekly or nightly for extra nourishment.
• Apply after serums and moisturizers as the last step.
• Adjust amount based on seasonal dryness or personal preference.

What visible changes can I expect after regular use?

With repeated use, expect plumper-feeling skin, reduced tightness, and a softer surface texture by morning. The combination of rice extract and niacinamide aims to deliver a subtle brightening effect and refreshed-looking skin without aggressive exfoliation.

• Improved hydration and skin suppleness upon waking.
• Smoother texture and a more even-looking complexion over time.
• Non-greasy finish suitable for layering under morning skincare.

Who is this for: The COSRX Ultimate Nourishing Rice Overnight Spa Mask is ideal for anyone seeking a gentle, hydrating overnight treatment—especially those with dry, combination, sensitive, or dull skin wanting a non-irritating boost in moisture and radiance. If you prefer lightweight sleep masks that layer well with serums and avoid harsh ingredients, this formula fits neatly into both minimalist and multi-step routines.
