Blake Lively has been practically glowing at Cannes (don’t even get us started on her Cinderella dress), and while we’re still not 1,000% sure if a maybe baby-on-board has anything to do with it (though we certainly have our suspicions, based on this bump!), we know now that one beauty product in particular is likely a large contributing factor to getting her signature fresh and dewy look.

Thanks to makeup artist Charlotte Tilbury (soon to be releasing a fab new line of celeb-inspired lipsticks), who spilled the beans via her Instagram account, we know that Blake has been using a portable LED light called The Makeup Light ($360+) that apparently works wonders beyond belief.

“Getting the mesmerizing @blakelively ready in Cannes and thank you Blake for introducing me to the best kept secret @themakeuplight, it’s changed my life! THANK YOU!!!” Charlotte captioned this snap of her touching up the starlet.

Said to emulate the sun’s natural rays (meaning your makeup will look just as great outdoors as it does upon application), The Makeup Light is the perfect tool for celebs hitting all those outdoor red carpets (and anyone else looking to keep their makeup looking fresh once they hit the streets, AKA, all of us). Blake’s not alone on the celeb fan train, either — Paris Hilton is also an enthusiast!

“Just overwhelmed to see Paris lit up by The Makeup Light,” the company wrote.

Hey, if our makeup looks half as good as either of these two ladies’ does after using this product, we’re officially sold.
