Celebrity-founded skincare brands can be a gamble. Are you buying the product — or the star’s stamp of approval?

However, according to thousands of reviews and even Page Six Style’s own editors, Scarlett Johansson’s The Outset is one skin promise that delivers. Co-founded by Kate Foster, the clean beauty brand launched in 2020 and has since grown legions of devotees.

Case in point: the brand’s coveted Lip Oasis Glossy Treatment, which has sold out a whopping seven times so far and just got restocked.

Made with humectants and plumping peptides, the lip hydrator has nearly five-star reviews everywhere it’s sold. Not just another balm or gloss, it’s a hybrid skincare treatment for your lips with short- and long-term benefits.

According to clinical tests, it boosts lip hydration by 48% in four weeks. The key ingredients also include Maxi-Lip to moisturize and firm lips, squalane to help smooth lines and lactic acid to help brighten your pout.

And while shoppers have hailed it as “the best lip stuff” and “a miracle in a tube” on The Outset’s website, our own staffers are equally smitten.

“Lip Oasis is really a two-for-one product to me, because it feels like a treatment or balm but looks like a gloss,” shares Page Six Style Senior Writer/Editor Melissa Minton.

“It goes on really thick and luscious but isn’t sticky at all the way a pure gloss would be, and definitely makes my lips feel hydrated the entire time I’m wearing it until the product soaks in.”

Adds Minton, “When I’m wearing the Lip Oasis, I feel like I have ScarJo’s enviable big pout! It definitely gives an enhanced look and I often reach for it as the only product I put on top of a lip liner for a super natural yet made-up look.”

She’s also a big fan of The Outset’s sunscreen, saying it goes on “super smooth, then dries down to an almost tacky primer-like consistency that actually makes my makeup look better.”

Speaking about what inspired her to launch The Outset, Johansson told the “Gloss Angeles” podcast in 2020, “I didn’t want to represent someone else’s ideal beauty standard and I finally had the confidence to do something on my own.”

She certainly has established her own standards with this cruelty-free, accessible, clean and inclusive skincare line that’s truly going places. And with no single product costing more than $54, customers say the products perform like far pricier ones.
