How to Use Them

Apply a thin, even layer as the last step of your evening routine, after moisturiser. You do not need much — a 10p coin-sized amount covers the whole face. Leave overnight and rinse off with your morning cleanser. Use 2-4 times per week, or nightly during particularly harsh weather.

Pillow Considerations

Modern sleeping masks are designed not to transfer, but using a silk or satin pillowcase is sensible regardless. These materials cause less friction, reduce sleep creases, and do not absorb product from your face the way cotton does.

The Four Best Options

Laneige Water Sleeping Mask The original and still the benchmark. Its gel texture absorbs quickly, does not feel sticky, and delivers intense hydration through squalane and a proprietary mineral water complex. It works for every skin type, which is rare for a sleeping mask. The slight fragrance is pleasant but worth noting for those with sensitivities.

COSRX Rice Overnight Spa Mask The best option for brightening. Rice extract is a traditional Korean brightening ingredient, and at 68% concentration combined with niacinamide, this mask visibly improves skin tone and luminosity. It has a thicker, creamier texture than the Laneige, making it better for dry skin.

Purito Cica Sleeping Mask The rescue option. If your skin is irritated, over-exfoliated, or just angry, centella and panthenol work overnight to calm inflammation and repair the barrier. It is the most therapeutic of the four — less about glow and more about healing.

COSRX Honey Overnight Mask At 87% propolis extract, this is the most nourishing option. The rich, honey-like texture provides deep moisture and antibacterial protection. Best for dry to normal skin during winter months when your skin needs maximum overnight recovery.

Why They Work So Well

Your skin does most of its repair work at night. Cell turnover accelerates, blood flow to the skin increases, and growth hormone levels peak. A sleeping mask supports this process by providing a constant supply of hydration and active ingredients throughout the repair window, whilst the occlusive layer prevents the transepidermal water loss that naturally occurs during sleep.

The result is genuinely visible the next morning. Skin looks plumper, more hydrated, and more luminous after a single use. With consistent use (3-4 times per week), the cumulative effect on skin texture and tone is significant.

What Are Sleeping Masks?

Sleeping masks — also called overnight masks or sleeping packs — are the final step in an evening skincare routine. They form a breathable, occlusive layer over your other products, locking everything in whilst you sleep. They also deliver their own active ingredients throughout the night, taking advantage of the skin's natural repair cycle that peaks between 11pm and 2am.

They are not the same as a heavy night cream. Sleeping masks tend to have lighter, gel-like textures that do not transfer onto your pillow, and they contain higher concentrations of active ingredients than standard moisturisers.
