Thank you for your consideration. The following is a product description: [Contains 5,000ppm of ultra-low molecular weight collagen (200Da)] This mask contains 5,000ppm of collagen itself, not collagen water or collagen extract. The fine collagen particles of 200Da penetrate deep into the skin, providing elasticity. When converted to ppb, the collagen content reaches approximately 5,000,000ppb, making it an ultra-realistic collagen pack. [Mask pack containing a whole 40g ampoule] A generous 40g ampoule packed with rich nutrients is included in each mask sheet. The excellent adhesion prevents the mask 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 leaving the transparent pack on for more than 3 hours, you can peel it off and immediately feel the skin's elasticity and radiant glow. [Completed 11 types of human application tests for intensive skin care] Completed approximately 11 types of skin management human application tests, including skin elasticity, firmness, wrinkles, lifting, two-layer moisturizing, soothing, skin tone, and skin radiance. The product has also passed the primary skin irritation test, making it gentle on the skin and suitable for sensitive skin. [Sleeping pack that nourishes the skin from the inside while you sleep] In addition to ultra-low molecular weight collagen, this mask pack is formulated with VINNE's unique blend of high-purity glutathione, 3rd generation MICRO PDRN (Banana PDRN), AquaJuve 3500, and acetyl hexapeptide.
