A sleeping mask is an overnight skincare treatment designed to deeply hydrate, nourish, and restore the skin while you sleep. Also known as an overnight mask or sleeping pack, it works as the final step of your evening skincare routine, creating a protective layer that helps lock in moisture and active ingredients throughout the night. As your skin naturally repairs itself during sleep, a sleeping mask supports this process, helping you wake up to a complexion that feels softer, smoother, and more refreshed.

Unlike traditional face masks that are rinsed off after a few minutes, sleeping masks are left on overnight to provide continuous hydration and care. Simply apply an even layer after your serum and moisturizer, or in place of your moisturizer, depending on the product, and leave it on while you sleep. By morning, your skin will feel hydrated, comfortable, and revitalized, making sleeping masks an easy way to give your complexion an intensive boost with minimal effort.

Korean sleeping masks are available in formulas for every skin type and skincare concern. Hydrating masks often contain ingredients such as hyaluronic acid, ceramides, and squalane to replenish moisture, while soothing formulas feature centella asiatica, heartleaf, mugwort, or aloe vera to calm sensitive skin. Brightening sleeping masks may include niacinamide or rice extract, while anti-ageing options are enriched with peptides, collagen, snail mucin, or fermented ingredients to improve the appearance of fine lines, elasticity, and overall skin texture.
