LANEIGE Water Sleeping Mask EX — Masque Nocturne Hydratation

The Water Sleeping Mask EX is based on a meticulous clinical formulation, tested on 32 volunteers to demonstrate that it replicates the effects of 4 extra hours of sleep on the epidermis.

3X Hyaluronic Night Blend : three forms of hyaluronic acid (Sodium Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Hyaluronic Acid) work synergistically to saturate the skin layers with water, from the surface to the deep tissues. Each molecular weight targets a distinct hydration level.

Niacinamide (Vitamin B3): evens out skin tone and strengthens the skin barrier by stimulating the production of endogenous ceramides, while limiting trans-epidermal water loss during the night.

Squalane : a biomimetic lipid of human sebum, it smooths the hydrolipidic film without an occlusive effect, ensuring rapid absorption and zero transfer onto the pillow.

Lactobacillus Ferment Lysate : a fractionated probiotic that soothes nighttime micro-inflammations and boosts radiance upon waking, a key component of the Sleeping Microbiome™ complex patented by LANEIGE.

Ceramide NP : a natural ceramide that seals micro-cracks in the barrier to lock in hydration until morning.

☀️ Morning routine

This mask is for nighttime use only. In the morning, rinse with lukewarm water to remove residue, then continue with your usual routine (toner, serum, SPF).

🌙 Evening routine

1. Cleanse your face (double cleansing if wearing makeup)
2. Apply your toner or essence
3. Apply your serum (if you use one)
4. Apply your night cream
5. As the last step, take a small amount of Water Sleeping Mask
6. Dot it on your forehead, cheeks, nose, and chin
7. Spread in upward motions, without rubbing excessively
8. Let the bluish film form (30 seconds), then go to sleep

Frequency: 2 to 3 times a week, or every night if your skin is very dehydrated. Rinse in the morning.

The light gel-water texture and non-comedogenic formulation of the Water Sleeping Mask suit a wide range of skin types:

• Dehydrated skin that feels tight upon waking and shows pronounced dehydration fine lines by the end of the day
• Dull or tired skin due to stress, lack of sleep, screens — the antioxidant malachite extract revives radiance
• Combination skin seeking nighttime hydration without greasy feel or residual shine (squalane is non-occlusive)
• Normal to dry skin wanting to strengthen their skin barrier and prevent water loss during sleep
• Fans of Korean layering who want to seal their multi-step routine under a protective veil all night

Avoid if : very oily skin prone to cystic acne (prefer the Cica Sleeping Mask from the same range), known fragrance allergy (limonene, linalool present).

The results measured during the instrumental clinical study reveal an improvement in hydration, elasticity, brightness, and radiance equivalent to that observed after 8 hours of sleep — while the participants had only slept 4 hours.

Upon waking (Day 1) : 100% of participants notice an improvement in the skin barrier and a reduction in water loss. The complexion appears rested, and the epidermis feels plump to the touch.

After one week of use (3 applications) : skin texture refines, radiance increases by 26.3% compared to untreated skin, and sallowness (yellowish complexion) significantly decreases.

Continuous use (2-3 times/week over 4 weeks) : lasting strengthening of the barrier, better tolerance to daily aggressions, makeup lasts longer thanks to a smoothed and hydrated surface. No anti-aging claims made, but deep hydration visually reduces dehydration fine lines.

What is the difference between the Water Sleeping Mask EX and the previous version?

The EX version includes the Sleeping Microbiome™ complex (with Lactobacillus Ferment Lysate) and the 3X Hyaluronic Night Blend, which are absent from the original formula. It further strengthens the skin barrier and boosts radiance upon waking.

Can I use it every night or only 2-3 times a week?

LANEIGE recommends 2-3 times a week for regular use. If your skin is very dehydrated or during winter, you can apply it every night without worry — the formula is non-comedogenic and clinically tested for frequent use.

Does the mask leave marks on the pillow?

No. The gel-water texture absorbs quickly and forms an invisible film that does not transfer. In the satisfaction study, 100% of users confirmed zero transfer onto the pillowcase.

Should I apply a night cream underneath or is the mask enough?

The Water Sleeping Mask is applied after your usual night cream, as the last step. It acts as a sealant that locks in the previous active ingredients. If you have very dry skin, keep your cream; if you have combination skin, you can try the mask alone after serum.

Is the lavender-chamomile scent strong?

The Sleepscent™ is subtle and evaporates after a few minutes. It contains natural notes of lavender, chamomile, and sandalwood to promote relaxation, but it is not an overpowering fragrance. If you are very sensitive to scents, do a patch test.

How long does a 70 ml jar last?

Used 2-3 times a week with a pea-sized amount (about 1 ml per application), the jar lasts 4 to 5 months. With daily use, expect 2 to 3 months.

Since 1994, LANEIGE (pronounced "la-nèj," meaning "snow" in French) has embodied the hydration expertise of its parent company Amorepacific. The brand was built on the Science of Water, with proprietary patents derived from research on nocturnal skin biology. The Water Sleeping Mask, launched in 2002 and reformulated in 2015, has become a global phenomenon: one unit sold every 13 seconds in 2024, favored by Asian tourists seeking effective and sensory skincare.

The LANEIGE philosophy is based on the concept of "Sparkle My Way": revealing each person's natural radiance through intelligent hydration, adapted to the skin’s circadian rhythms. The SLEEP-TOX™ and MOISTURE WRAP™ technologies are the result of decades of R&D on nighttime regeneration. Today, the Sleeping Masks range includes several variations (Cica, Bouncy & Firm) to meet all needs, but the Water remains the iconic bestseller, regularly awarded (Cosmopolitan Beauty Readers' Choice Awards Hall of Fame 2025).
