May Island's 7 Days Ampoule is a Korean single-dose treatment concentrated with hyaluronic acid and cactus (opuntia) extract to deliver an intensive burst of hydration to dehydrated, tired skin. The formula also features collagen and green tea (Camellia Sinensis) extract to help support elasticity and calm the skin. Packaged in individual 3g sachets, it's convenient for travel or for a focused 7-day hydration routine, and is gentle enough for most skin types, including sensitive skin. After cleansing and toning, tear open a sachet and pat the ampoule into the skin before following with moisturizer. It works well as a standalone hydration boost or layered into an existing routine when skin needs extra plumping.
