Collagen Sheet Mask.

"I absolutely adore this brand's film forming masks. [...] They take advantage of occlusion therapy, where you apply a hydrating moisturizing product to the skin and cover it with a dressing, in this case the mask, which maximally locks in hydration and allows for penetration of ingredients in a more focused and effective manner. That said, this approach can be more irritating. [...] It looks like a typical hydrogel sheet mask, but it dries down and forms a semi-transparent adherent film, like a mask adhered to your face. It looks bizarre [...] but it's very comfortable to wear and stays in place. It does take a bit of time to dry down, so you need to be patient with it, which is one of the reasons I don't do these more often, but whenever I do, I always wake up the next morning with skin that's hydrated, plump, and dewy. It's an excellent way to calm and soothe the skin and get targeted improvement in overall skin tone and clarity. This particular variant contains ceramides for barrier repair, niacinamide which targets redness and discoloration and helps the moisture barrier, [...] licorice root compounds to calm and reduce redness, and a variety of forms of hyaluronic acid to improve water content in the skin's outermost layer. You can comfortably wear it to bed and it stays in place all night."

"This sheet mask is basically, they pour one bottle of the serum into the mask, so when you leave it on for three or four hours, even overnight, you get a lot of hydration. I tried it multiple times but ended up not using it that much because it takes so much effort for such a short glow. It's definitely hydrating but it doesn't last that long, so I don't think I need to invest in it that much. You can try it for fun. Between the many brands that copy this kind of gel mask, Biodance works a little better overall and the sheet feels pretty soft, but I still won't recommend it that much."
