This overnight mask is a multifunctional treatment designed to deeply hydrate, brighten, and smooth your skin while you sleep. Formulated with a high concentration of rice extract and niacinamide, it helps to fade dullness and uneven tone, leaving your skin looking clearer and more radiant in the morning. Its creamy texture provides intense nourishment and seals in moisture, making it a perfect final step for a dewy and plump complexion.

Best for: All skin types, particularly those with dry, dull, or uneven skin tone looking for a deep hydration boost and brightening effect. It is also suitable for those who want to improve their skin's texture and radiance.

Using this product is a simple and effective final step in your evening routine:

• 1) Cleanser — start with a gentle cleanser to prepare your skin.
• 2) Serums or treatments — apply any serums or treatments as usual.
• 3) This product — use a thin layer to seal in all the prior steps and provide deep nourishment.

This product is an overnight mask, so it is not intended for morning use. Your morning routine should focus on gentle cleansing, hydration, and sun protection.

• 1) Cleanser — quick wash to remove any residue.
• 2) Hydrating Toner/Essence (optional) → 3) Moisturiser — seal & protect.
• 4) Sunscreen SPF 30+ — always the last step.

Wait times: 30–60s between watery layers; 1–2 min before SPF/makeup.

This product is designed as the last step in your evening routine to provide deep hydration and nourishment while you sleep.

• 1) Cleanser (double-cleanse if makeup/water-resistant SPF: oil → water) — thoroughly wash away makeup, sunscreen, and daily grime.
• 2) Serums/Essence — apply any desired serums or essences.
• 3) This product — apply a nickel-sized amount as the final, occlusive layer to lock everything in.

Weekly Use — PM only:

• Amount: Use a nickel-sized amount for your face and neck.
• Apply to: Your face and neck. Avoid the lip and eye areas.
• Method: As the last step of your evening skincare routine, gently apply a thin layer over your face. Pat it in lightly to help absorption. Leave it on overnight and rinse in the morning.
• Frequency: Use 2–3 times per week, or as needed, as an alternative to your regular moisturizer.

Dosage quick-table:

• Sleeping Pack: nickel-size; 2–3×/week as last PM step.

If-This / Then-That:

• Very oily T-zone? Use a very thin layer to provide nourishment without feeling heavy.
• Very dry/AC? This product is ideal for deep hydration and barrier repair in dry conditions. Use it over a hydrating toner or essence for an added boost of moisture.

Watchouts: Pilling = not an issue; sensitivity = avoid on damaged or broken skin. This product has a creamy texture, which can feel too rich for some oily skin types in humid climates.

Safety: Avoid broken/irritated skin. Stop if burning rash. Teens: this is a gentle, beginner-friendly overnight mask that can be incorporated into a simple cleanse–moisturise–SPF routine.

This is a gentle daily item. It can be used daily, morning and night, as per the routine maps, to keep skin hydrated and calm.

PM/AM cheat-sheet: Sleeping Pack 2–3×/week as last PM step.

Mauritius note: In heat/humidity, use a thinner layer and perhaps only 1-2 times per week. In drier months or in air conditioning, increase frequency for barrier support.

Safety: If irritation occurs, reduce frequency to 2×/week, switch to soothing nights, and follow patch-test guidance.

Immediate: Skin will feel nourished and deeply hydrated. You will wake up with a radiant and "glass-like" complexion that feels soft and supple.

2–4 weeks: With consistent use (2–3 times a week), you may notice a significant improvement in skin hydration and texture. The nourishing ingredients help to repair the skin barrier, leading to a reduction in flakiness and dullness.

4–8+ weeks: Continued use helps to maintain a healthy and resilient skin barrier. The product helps to protect against inflammation and environmental stressors, contributing to a more even tone and a healthier, long-lasting glow.

• Oils: This sleeping mask provides deep nourishment and occlusion without the potential for comedogenicity that some heavy oils can cause.
• Night creams: This mask can act as a more intensive version of a night cream, sealing in all your evening skincare steps and providing a concentrated dose of hydrating and soothing ingredients.

Works with:

• Most actives: This mask is designed to be the final step, so it is safe to layer over most other actives, such as niacinamide, peptides, or even retinoids, as it helps to buffer and moisturize.
• Brightening serums: It pairs well with brightening serums containing niacinamide, vitamin C, or alpha-arbutin for an enhanced effect on dullness and uneven tone.

Use carefully:

• High-potency exfoliants: While it can be used on nights when you exfoliate, avoid using a very thick layer, as it may feel heavy on the skin. A light application is best.

This product is generally suitable for all skin types. It is particularly beneficial for dry, dehydrated, and mature skin that needs deep nourishment. Oily or combination skin types can use a thinner layer or use it infrequently for a moisture boost without feeling heavy.

This overnight mask targets a variety of concerns, including:

• Dull, tired-looking skin.
• Dryness and dehydration.
• Compromised skin barrier.
• Redness and inflammation.
• Fine lines and wrinkles.

• Official Korean Name: 코스알엑스 얼티밋 너리싱 라이스 오버나이트 스파 마스크
• Shelf Life/PAO: PAO is 12 months.
