3W Clinic Fresh Collagen Mask Sheet is a Korean hydrating sheet mask soaked in 23 ml of essence. It contains hydrolyzed collagen, sodium hyaluronate, betaine and allantoin, which help moisturize and soften tired, dull-looking skin. The soft, flexible sheet clings closely to the face, so the essence has time to absorb and the skin looks plump, smooth and refreshed. It is easy to use and suits weekly or occasional care, as a quick moisture boost before makeup, after sun exposure or whenever skin feels dry. Each sheet is individually packed, which makes it hygienic and travel-friendly.
