Liposome vitamin technology: why some sheet masks wrap actives in a fat bubble first

What a liposome actually is in cosmetic formulation

A liposome is a microscopic spherical structure made of a lipid (fat) bilayer that can encapsulate a water-soluble active ingredient inside its core — because the outer shell is lipid-based, it can merge more readily with the skin's own lipid barrier than an unencapsulated water-soluble vitamin could on its own.

Why vitamins specifically benefit from liposome encapsulation

Many active vitamins used for brightening are water-soluble, which limits their ability to pass through skin's naturally lipid-rich outer barrier — wrapping them in a liposome effectively disguises the water-soluble active in a lipid-compatible package, improving the odds it reaches slightly deeper into the skin rather than remaining on the surface.

Why a jelly sheet mask format pairs well with this technology

A jelly-type mask sits in closer, more even contact with skin than a standard non-woven sheet, and holds its serum load for the full wear time rather than drying out quickly — this extended, even contact gives the liposome-encapsulated vitamins a longer window to reach and release their contents at the skin's surface.

What Jeju aloe leaf water is contributing alongside the vitamin delivery system

Aloe leaf water is included primarily for its own hydrating and mildly soothing properties, functioning as the mask's base hydration layer — a separate, complementary role from the liposome vitamin technology, which is specifically focused on getting the brightening actives into the skin rather than on hydration itself.

Setting expectations for a single mask application

Even with an improved delivery mechanism, a single 15-20 minute mask application produces a temporary, visible brightening and hydration boost rather than a permanent change — liposome technology improves how efficiently the actives are delivered during that window, not how long a single use's effects will last afterward.
