They brighten and hydrate my skin, with the effects lasting up to 48 hours. I don't know if there are any long term benefits to using them consistently, but they work amazingly for special occasions or any time I want to look a little better for a day or two. Despite the fragrance, they don't irritate my skin and actually provide relief from redness. 

Honestly the Etude House 0.2mm masks are my favorites! And they're really inexpensive. Just choose the the "ingredient" your face needs the most! This one is especially good for redness.
