These masks are infused with various beneficial ingredients, such as hyaluronic acid, ceramides, or natural extracts, which help improve skin texture and appearance by morning.
According to the Korean skincare brand Laneige, their Water Sleeping Mask significantly boosts hydration levels in the skin, providing a refreshing feel and a radiant complexion upon waking.

To maximize the effectiveness of a Korean sleeping mask, best practices include applying it on clean, toned skin after a complete skincare routine, allowing it to absorb fully before sleeping. Users should also layer the mask over lightweight serums or essences to boost hydration further. For those with sensitive skin, patch testing new products is advisable to avoid irritation. Additionally, consistency in use, ideally 2-3 times a week, can help achieve optimal results and maintain healthy skin.
