Product Description: [Contains 5,000ppm of 200Da ultra-low molecular weight collagen] This mask contains 5,000ppm of collagen itself, not collagen water or collagen extract. The fine 200Da collagen particles 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. [A mask pack containing a full 40g ampoule] A rich, concentrated 40g ampoule packed with nutrients is included in each mask. The 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 the transparent pack for more than 3 hours, you can peel it off and immediately feel the skin's elasticity and radiant glow.
