Leslie Mann has revealed she is hooked on the €25 Laneige Lip Sleeping Mask as part of her bedtime skincare routine.
The 54-year-old American actress shared details of her nightly beauty habits during an interview with digital publication Air Mail, explaining that she relies on the Korean cosmetic treatment to wake up with soft and hydrated lips.
Mann acknowledged that she is not the most disciplined person when it comes to maintaining a strict beauty regimen. While she keeps a drawer filled with cosmetic products and uses different items depending on the occasion, she noted that the Laneige lip mask has earned a dedicated spot beside her bed.
Speaking to Air Mail, Mann confessed that she is completely hooked on the Laneige lip balm. She questioned what ingredients are included in the formulation, adding that there must be a secret component that keeps users coming back for more.
Born in San Francisco, California, Mann has worked as an actress in Hollywood for more than three decades. She is best known for her starring roles in hit comedy films including Knocked Up, This Is 40, 17 Again, and The 40-Year-Old Virgin.
Air Mail, where Mann shared her routine, is an online weekly publication launched in 2019 by former Vanity Fair editor-in-chief Graydon Carter and former New York Times correspondent Alessandra Stanley, focusing on international culture, fashion, and lifestyle news.
Bedtime Skincare and K-Beauty Favorites
In her interview, Mann explained that she spends a few minutes on skincare each night before going to sleep. On certain evenings, her routine also includes applying Korean facial masks to nourish her skin.
The item highlighted by the actress is the Lip Sleeping Mask by Laneige, an overnight treatment that has become one of the most iconic products in Korean cosmetics. Laneige closed the first half of 2026 as the top-selling lip care brand at Sephora Spain.
Laneige is a South Korean cosmetics brand founded in 1994 by Amorepacific Corporation, South Korea's largest beauty conglomerate. The term K-Beauty refers to Korean skincare philosophies and products emphasizing gentle formulations, skin barrier protection, and intense hydration routines.
Sephora is a global beauty retailer founded in France in 1969 and acquired by luxury conglomerate LVMH in 1997. Operating thousands of stores worldwide, including Sephora Spain, the retailer's sales charts serve as a major benchmark for popular beauty trends across European markets.
Formula Ingredients and Overnight Hydration
The Lip Sleeping Mask is designed to work specifically while users sleep. Applied before bedtime, the rich texture forms an enveloping layer over the lips that helps retain moisture throughout the night.
The treatment's formula features nourishing ingredients including coconut oil, shea butter, and murumuru seed butter. These components are combined with Berry Fruit Complex, which is rich in antioxidants, alongside vitamin C to help shield lips against external environmental factors.
The intended result is for users to wake up to lips that feel smoother, softer, and more flexible, particularly when they start to feel dry or chapped.
Murumuru seed butter is harvested from the seeds of the Astrocaryum murumuru palm native to the Amazon rainforest, valued in cosmetics for its high concentration of fatty acids that restore skin elasticity. Shea butter is extracted from the nuts of the African shea tree, serving as a rich emollient, while coconut oil provides an occlusive layer that seals in hydration.
Lip skin is thinner than skin elsewhere on the face and lacks oil glands, making it particularly vulnerable to dryness and environmental damage. Antioxidants like vitamin C in lip formulations help neutralize reactive free radicals while supporting the delicate skin barrier.
Daytime Applications and Makeup Preparation
Although designed primarily as an overnight treatment, the product does not have to be reserved solely for bedtime. Users can apply a thinner layer during the day to use the product as an intensive hydrating balm whenever extra moisture is needed.
The mask can also be integrated into a morning routine as a preparatory step before applying makeup. Applying a layer prior to lipstick helps smooth the surface of the lips, creating an even base that improves the finish and prolongs the wear of lip color.
This combination of multi-use versatility and hydrating performance explains why the product has achieved widespread popularity within K-Beauty and remains an essential staple in Mann's beauty drawer.
