COSRX Ultimate Nourishing Rice Overnight Spa Mask 60ml — 68% Rice Extract & 2% Niacinamide for Hydration & Brightening

COSRX Ultimate Nourishing Rice Overnight Spa Mask is an overnight treatment that hydrates, calms and visibly brightens skin using 68% rice extract and 2% niacinamide.

Designed to be applied as the final step in your evening routine, this Korean spa-style sleeping mask channels traditional rice-based skincare with modern actives for a softer, more even-looking complexion by morning. The lightweight yet nutrient-dense formula absorbs while you sleep, delivering moisture and replenishment without heavy residue. It’s formulated to be cruelty-free and free from common irritants like parabens, sulfates and phthalates.

How does this sleeping mask hydrate without feeling greasy?

The mask combines a high concentration of rice extract with humectant and barrier-supporting ingredients to draw moisture into the skin and lock it in overnight. Texture-wise it spreads smoothly, absorbs into upper layers of the skin and leaves a dewy, non-oily finish that won’t transfer heavily to pillowcases when dabbed in moderate amounts.

• 68% rice extract for immediate calming and moisture replenishment
• Niacinamide 2% helps improve skin tone and surface texture
• Light, spa-like gel-cream texture that absorbs without heavy residue
• Apply a thin to moderate layer as the last evening step

Will this mask help improve dullness or uneven tone?

Yes — the inclusion of 2% niacinamide and concentrated rice extract targets dullness and helps the skin appear more radiant with consistent use. Niacinamide is a multitasking ingredient known for supporting skin tone and minimizing the look of fine surface irregularities, while rice extract contributes brightening and calming benefits historically valued in East Asian skincare.

• Niacinamide 2% for brightening and skin-surface refinement
• Rice extract supports natural radiance and soothing
• Regular overnight use enhances morning luminosity

Can sensitive or reactive skin types use this product safely?

The formula is designed to be skin-friendly and hypoallergenic, developed under COSRX’s standards for gentle, effective care. It’s dermatologist tested and free from parabens, sulfates, phthalates and animal testing, but as with any active-containing product, a patch test is recommended for those with very reactive skin.

• Hypoallergenic and dermatologist tested formulation
• Free from parabens, sulfates and phthalates
• Patch test recommended for highly reactive skin

How should I incorporate this mask into my nightly routine?

Use this mask as the final step after cleansing, toning and any treatment serums. Apply a generous but even layer over the face and neck, leave on overnight, and rinse or gently pat remaining residue in the morning as needed. Frequency can range from nightly to several times a week depending on your skin’s hydration needs.

• Step 1: Complete your regular evening routine (cleanse, treat, hydrate)
• Step 2: Apply an even layer of the mask as the final step
• Step 3: Leave on overnight and rinse or pat excess in the morning

Who is this for: This sleeping mask is suitable for anyone seeking an overnight boost in hydration and radiance — especially those with normal to dry or combination skin that benefits from calming, nourishing treatments. It’s also a good choice for users who want a clean, Korean skincare formulation free from common irritants and animal testing. If your skin is very oily or acne-prone, use moderated amounts and monitor how it responds before adopting nightly use.
