Peggy Gou is stepping back into the spotlight for Beauty of Joseon, this time to unveil the brand’s newest launch: the Dayscreen Moisturizer SPF 30.
The K-beauty brand has tapped its global ambassador to front the new Dayscreen, a green tea-powered hybrid that hydrates and protects skin in one step, absorbs fast, and leaves zero white cast.
The product joins Beauty of Joseon’s growing sunscreen family, which now spans formulas for every skin preference, from the original viral Relief Sun to last year’s dewy Day Dew SPF 50.
This is the second major product launch Gou has headlined for the brand since she was first named global ambassador and starred in the equestrian-themed “Not Our First Rodeo” campaign for the Day Dew Sunscreen SPF 50.
The move also coincided with Beauty of Joseon’s landmark Sephora debut, its first major U.S. retail expansion The brand’s U.S. sales goal sits at $120 million, with Sephora playing a central role in hitting that target.
Off the beauty shelf, Gou has been equally busy building her brand portfolio. She recently designed a limited-edition bottle for Don Julio 1942 and collaborated with Alpha Industries on a limited capsule blending military precision and nightlife energy She has also been named a global ambassador for Maybelline New York.
This brand strategy is not unlike what we’ve seen from other artists crossing into beauty, much like how Hailey Bieber brought Justin Bieber into her Rhode launch campaign to amplify cultural reach, or how Megan Moroney fronted Revlon’s Be Unforgettable campaign to bridge music fandom and beauty consumers.
For Beauty of Joseon, the Gou partnership continues a pattern of culturally intentional casting. Prior to Gou, the brand had also run a campaign featuring designer Sandy Liang, signaling a deliberate effort to reach style-savvy Western audiences.
Takeaways
This isn’t just another celebrity slapping their name on a sunscreen. Peggy Gou and Beauty of Joseon are now entering their second product launch together, and that consistency is rare in a beauty landscape that often burns through ambassadors fast. What started as a splashy Sephora debut moment has quietly become a durable brand relationship.
Beauty of Joseon is playing a long game: each Gou-led launch expands its SPF lineup while keeping the same face front and center, building genuine brand equity rather than chasing a one-time viral hit.
For Gou, it’s a smart play too, adding a K-beauty anchor to a portfolio that already spans tequila, military fashion, and cosmetics. She’s not just a DJ with deals; she’s becoming a cultural commerce engine.
Does a DJ-led sunscreen launch make you more curious to try K-beauty SPF? Are music stars becoming the new faces of skincare more than traditional actors and models?
