First time I've used sheet mask. Can't comment much besides I love the scent. 

There is a lot of product in it ! 

I like it to brighten my skin when it seems tired and I use a good moisturizer afterwards ! 

Very pleasant to use because the mask is thin and light :)

This mask does a really good job hydrating my face and the effect lasts quite long. 

The smell is nice and it moisturizes really well. I didn't notice any brightening though.
