@wishformula Bat Eye Essence Mask claims to have an anti-wrinkle, anti-aging and brightening effect on the undereye area, center of forehead and nose using centella and fermented honey essence. It contains many additional extracts (depending on what source you're reading) like olive leaf, peppermint leaf ferment, burdock, centipede (!!!!), among others. It also contains adenosine, panthenol and allantoin - all great skin-friendly ingredients - and alcohol/paraben-free. I found the essence to be scent-free and on the watery side, with about a teaspoon leftover. The "bat head" portion of the eye mask didn't quite extend to the center of my forehead, or even between my eyebrows. The material was cotton. The website says to leave it on for 20-30 minutes. I could tell that it would have dried out before the 20-minute mark so I used a silicone mask on top of the eye mask. I left it on for 30-40 minutes. I'm in my early fifties but don't have many wrinkles around my eye. I do, however, have dark circles (ugh). When I removed the mask, there was no "ta-da!" moment. My undereye area did seem less puffy and was hydrated. I think I'd have to use it on a daily basis for any real brightening results. It absorbed well and didn't leave my skin feeling tacky. With all these great ingredients, I was expecting more but overall, it was a good product.
