1 / 6Bio-Collagen Real Deep Mask (4 pk)
An overnight hydrogel mask that goes on as a thick, milky, jelly-like film and slowly turns transparent as your skin absorbs the serum inside. You wear it for at least 3-4 hours — many people just sleep in it — and peel it off to skin that looks plumper and smoother. A solid pick for dry or dehydrated skin, or the night before you want to look especially rested.
More detail
Each pouch holds a two-piece hydrogel mask carrying 34 g of ampoule built around ultra-low-molecular-weight hydrolyzed collagen and oligo-hyaluronic acid — humectants that draw water into the skin — plus galactomyces ferment and niacinamide for added hydration and a brighter look, with allantoin and licorice-root extract to help calm. Use it after cleansing (and toner if you like): peel off the backing films, smooth the top and bottom halves onto your face, and leave it on for 3-4 hours or overnight, removing it once the milky film has gone clear. The texture is a cool, jelly-like gel that clings well enough to stay put while you sleep. The formula is alcohol-free with no added fragrance, though it does include rose flower water, which naturally carries some fragrant compounds — worth noting if you're very fragrance-sensitive. It also contains fermented ingredients (galactomyces, lactobacillus ferment), so a patch test is sensible if ferments have bothered your skin before. Expect a plump, dewy hydration effect that's temporary — great before an event — rather than a lasting structural change.
