From my experience sleeping masks are usually heavy and sticky and overall uncomfortable, but this overnight mask from Cosrx was a pleasant surprise - while the finish isn't obviously matte, it is not as sticky as I expected it to be. The mask has no smell, I expected a honey smell but it smells like nothing - good for those who don't like heavily perfumated skin care products. I have not noticed big difference in my skin after waking up but I will keep using it because it might take time.
