When the collagen content is converted to ppb, it reaches approximately 5,000,000ppb, making it an ultra-real collagen pack. [Mask pack containing a whole 40g ampoule] A rich, concentrated 40g ampoule packed into a single mask pack. Excellent adhesion prevents it from peeling off, allowing you to care for your skin while doing other activities. [Visible absorption process] The white mask sheet becomes transparent over time as it delivers beauty ingredients deep into the skin. After applying for 3 hours or more and removing the transparent pack, you can immediately feel the skin's elasticity and a radiant, glowing complexion. [11 types of human application tests completed for intensive skin care] Completed approximately 11 types of human application tests for skin elasticity, firmness, wrinkles, lifting, two-layer moisturizing, soothing, skin tone, and skin radiance.

[Sleeping pack that nourishes the skin from the inside while you sleep] In addition to ultra-low molecular weight collagen, this mask pack, born from VINNE's unique formulation of high-purity glutathione, 3rd generation MICRO PDRN (Banana PDRN), AquaJuve 3500, and acetyl hexapeptide, nourishes the skin with high-purity nutrients from the inside while you sleep, and you can see the smooth skin elasticity and bright skin tone in the morning.
