Anne Hathaway's double eye mask trick is 20% off

Anne Hathaway posted a GRWM reel on Instagram last week. She rolled into the room in a white tank and sunglasses before the opening of her film "Verity." When she lifted her sunnies, she revealed eye masks on both her upper and lower eyes. That is a double masking habit she has done before.

The masks are from 111Skin, a British brand founded by physicians. Page Six says Hathaway has used them for years. She wears the Celestial Black Diamond Eye Mask on her upper eyes for hydration and plumping. The blue Cryo De-Puffing Eye Mask depuffs under-eye bags and hydrates sensitive skin, promising a smooth, radiant look.

Here is the fun part: through tonight, both are 20% off. That is the final stretch of Amazon's October Prime Day. The sale runs Tuesday, Oct. 6 through Wednesday, Oct. 7, and it is exclusive to Prime members. You can get a 30-day free trial if you want in.

A fan review quoted by Page Six says: "I love this skin care line! I use the exfoliating powder as well. These eye masks are worth every penny. You will see results after 15 minutes! Mini eye lift every time!"

111Skin is an A-list favorite. Jennifer Aniston, Emily Blunt and Emma Roberts are also fans.

So if you want to mask like Hathaway, now is the time. Page Six has the full deal details.
