Korean sleeping masks are overnight treatments designed to seal in hydration and support the skin while you sleep. Applied as the final step of your evening routine, they usually have a gel, cream or balm texture that helps reduce moisture loss and leaves dry or tired-looking skin feeling softer by morning.

Choose hyaluronic acid for dehydration, ceramides or panthenol for barrier support, and soothing ingredients such as centella when your skin feels sensitive. Apply a thin, even layer over your moisturiser, leave it on overnight and rinse in the morning. Use a few times a week or as directed by the product.
