Billie Eilish Prepped Her Oscars Makeup with a Serum Shoppers Call the 'Most Effective' Treatment for Dark Circles

If you missed the Oscars last Sunday, that's fair. However, if you're like me and live for the fashion, the slow paced drama, and all of the hot goss, this year's ceremony did not disappoint. Even a newcomer to the awards like Billie Eilish came prepared with a standout look. Head to toe black from her gown to her bangs fit the emo-pop queen vibe without overdoing it. Juxtaposed to her dark, billowing dress was her super bright, clean makeup, which her makeup artist Robert Rumsey said was achieved with the Charlotte Tilbury Cryo-Recovery Eye Serum (Buy It, $68, nordstrom.com and sephora.com).

"We like to do flawless skin, moisturized lips, brushed-up brows and separated lashes. A little glow and some dimension," Rumsey told Vogue last year. Known for his "no-makeup" makeup looks, Rumsey adds that he likes to layer on hydration, and it's easy to see why he went with the Cryo-Recovery Eye Serum for the big night. Described by the brand as an "energizing alarm clock for the eyes," this was designed to mimic the effects of CoolSculpting therapy: Replexium, a patented peptide complex, plumps skin, reducing the appearance of fine lines and crow's feet. Meanwhile, a combination of caffeine and algae extract brightens dark circles and promotes elasticity. Finally, a cooling metal applicator diminishes puffiness.

One UK shopper, who called the serum "magic" wrote, "I've literally spent hundreds of pounds trying to find the right treatment for my puffy, dark under eyes, and in terms of cost, this is definitely the most effective." Another user recommended leaving the tube in your fridge overnight, adding that it "feels lovely after a long day" and has brightened their under eyes overtime. A third reviewer also noted that this serum absorbs well and has made "a huge, visible impact" in rejuvenating tired-looking skin. (Pssst: Dermatologists say these are the best eye creams.)

When it comes to wearing all black while still looking fresh and awake, we could all learn a lot from Billie. For an eye treatment that goes on smoothly under makeup and tackles the even the peskiest under-eye issues, head to Nordstrom and Sephora to check out a serum that's proven itself on the red carpet.
