What an overnight mask does
An overnight mask is a leave-on treatment you apply at night. It goes on as the last step of your evening routine. The mask adds a concentrated dose of hydration to your skin. It also helps slow water loss while you sleep. By morning, skin often looks plumper and softer. It tends to look less dull too. You rinse it away when you wake up. The effect is comfort and glow.
Most formulas are gel or cream textures. Laneige Water Sleeping Mask is the best-known gel option. Neutrogena Hydro Boost Hydrating Overnight Mask is an affordable drugstore pick. Glow Recipe Watermelon Glow Sleeping Mask adds a light, fruity feel. Each one seals in moisture overnight. Apply a thin, even layer so it absorbs before your pillow.
An overnight mask is a hydration boost, not a cure. It will not erase wrinkles or treat a skin condition. Think of it as a weekly or nightly comfort step. Dry, tight skin benefits most from the extra moisture. Even oily skin can use a lighter gel version. Choose a texture that feels good and does not clog you. An overnight mask is easy to add to any routine. It replaces nothing; it simply seals the end of your night. Use it when skin feels parched or looks tired. Winter and travel are prime times for the extra step. In summer, a lighter gel may feel better. Listen to what your skin needs that week.
A sleeping mask as a leave-on treatment for overnight hydration
A sleeping mask and an overnight mask are the same idea. Both are a leave-on treatment for overnight hydration. You do not wash them off before bed. Instead, they work with you through the night. Then I Met You Relief Sleeping Mask leans soothing and gentle. Innisfree Green Tea Seed Sleeping Mask offers a lightweight, budget option. Pick one that matches your skin.
Layering order matters for overnight hydration. Cleanse, then apply your usual serum and moisturizer. Seal everything with the sleeping mask as the final step. Summer Fridays R+R Overnight Recovery Mask doubles as a rich night treatment. The mask locks the earlier layers in place. That is how you wake up to plumper skin. Do not apply the mask too thickly, though. A heavy layer can transfer to your pillow. A thin, even coat absorbs and works just as well. Give it a few minutes to settle before lying down. A silk pillowcase can help reduce any transfer. Small habits protect the results.
You do not need a sleeping mask every single night. Two or three times a week is plenty for many people. Use it more often in dry weather or after travel. If your skin stays irritated or breaks out, simplify and see a dermatologist. A leave-on treatment should feel soothing. It is a supporting step, not the whole routine. An overnight mask boosts hydration; it does not treat conditions. It will not clear acne or fade set-in lines. What it does is leave skin soft and comfortable by morning. That quick win keeps many people consistent. Pair it with daytime sunscreen for lasting comfort. If breakouts or irritation follow, simplify and reassess.

It's become the benchmark of the category for a reason. This hyaluronic-acid-rich gel-cream noticeably plumps and softens skin by morning, without feeling heavy.
- Lightweight gel-cream absorbs without a greasy after-feel
- Noticeable overnight hydration improvement reported across a wide range of skin types

- Contains added fragrance (Laneige's own 'Sleepscent'), which can bother fragrance-sensitive skin
Hydro Boost Hydrating Overnight Mask
Neutrogena
A hyaluronic-acid gel formula that delivers the core benefit of the category: overnight water retention. It does that at a drugstore price point.
- Widely available and inexpensive relative to the category
- Oil-free gel texture suits oily and combination skin
- Fragrance is light compared to many prestige options
- Formula is fairly basic — no ceramides or added barrier-support ingredients beyond hyaluronic acid

Summer Fridays
A balm-like cream loaded with squalane, shea butter, and niacinamide. It's built for skin that needs real occlusion, not just a light gel.

- Jar formula layers well under or over other products in a cold-weather routine
