-
Exosome Technology and Vegan Sheet: Applies Vital Boosting Exosome technology, which is 1/2,000th the size of pores, to quickly deliver active ingredients. The eco-friendly moisture-retaining vegan-certified sheet prevents essence evaporation, maintaining close hydration.

👍 4. Summary of Real User Reviews
"Unlike light hydrating masks, the essence is really rich and provides a deep feeling of nourishment. After using the mask, I feel my skin's elasticity building up from within."
"In addition to the essence soaked in the sheet, there's a generous amount of essence left in the pouch, so I can apply it to my neck, collarbone, and even elbows after putting the mask on my face for thorough moisturizing care."
"Due to its highly moisturizing and nourishing formulation, it might feel slightly sticky or heavy for oily skin types who prefer a light and refreshing finish. However, it's perfect for me, with extremely dry or flaky sensitive skin that is severely lacking in nourishment."
⚠️ Cautions and Notes
-
Tip for Oily Skin: For oily skin, leaving the concentrated essence on the skin after removing the mask might feel heavy. Gently pat it in to absorb, then lightly wipe off any residue with a toner-soaked cotton pad for a fresher feel.
-
Adhere to Recommended Time: Although the sheet material itself is a special vegan sheet that retains moisture for a long time, it is best to remove the sheet before it completely dries, within the recommended time (10-20 minutes), for proper absorption of the nourishing ingredients.
