The Sacheu Lip Liner STAY-N has taken over TikTok and beauty routines worldwide. This peel-off lip stain promises all-day color that survives coffee, meals, and even kissing. But does it actually work? We tested it, talked to experts, and gathered everything you need to know. Kim Kardashian Met Gala 2026 featured a tangerine fiberglass breastplate by Allen Jones that was finished in an auto body shop in Kent, England. Here is everything you need to know about the Sacheu lip stain in 2026.
What Is the Sacheu Lip Stain?
The Sacheu Lip Liner STAY-N is a peel-off lip stain that works as both a lip liner and a full-coverage lip color. The brand sells one unit every five seconds online [citation:6]. It has become a staple in get-ready-with-me videos, with celebrities including Billie Eilish using it for pre-concert makeup [citation:1]. Sofia Richie Grainge and Alix Earle have also raved about it [citation:6].
Unlike traditional lip liners that fade within an hour, this formula uses a peel-off film technology. The product applies as a glossy black or blue gel. After it dries, you peel it off like a sticker. What remains is a vibrant, transfer-proof stain that can last up to 10 hours [citation:4]. Available in 14 shades ranging from nudes to deep berries, it suits all skin tones [citation:4].
Key Ingredients: What Makes It Work
The Sacheu lip stain contains several key ingredients that make it effective. Hyaluronic acid provides instant and lasting hydration [citation:7]. This prevents the stain from drying out your lips like traditional long-wear lipsticks. Vitamin E offers antioxidant-rich nourishment and protection [citation:2].
The hero ingredient is polyvinyl alcohol (PVA). This water-soluble polymer creates the peel-off film. Cosmetic chemist Laura Lam-Phaure explained to Allure: “Polyvinyl alcohol is the ingredient that gives the formula its peelable effect. It is a film-former that works by adhering to the lips, creating a flexible layer that can be peeled away once fully dry” [citation:8]. This film-forming property also enhances color payoff. It allows pigments to stain the lips effectively, locking in the color [citation:8].
The formula is fragrance-free, cruelty-free, and vegan [citation:5]. It is also free from sulfates, BPA, alcohol, and parabens [citation:2]. The FDA has approved PVA for cosmetic use, and dermatologists consider it safe for the skin in small amounts [citation:1].
How to Apply Sacheu Lip Stain: Step-by-Step Guide
Proper application is crucial for the best results. Follow these steps for a flawless finish.
Step 1: Prep Your Lips
Start with clean, exfoliated, dry lips [citation:5]. Professional makeup artist Amrita Mehta recommends using a lip scrub or a damp washcloth to gently slough off dead skin [citation:1]. Apply a lip mask or balm, then wipe it off. This hydrates your lips but leaves no excess oils or waxes that could affect the stain’s application [citation:1].
Step 2: Apply the Product
Trace the applicator along your lip line or all over your lips. Use a generous, even layer [citation:3][citation:5]. The product has a thick, semi-sticky texture. If it goes on patchy, it will look patchy when you peel it off, so re-dip the applicator to fill any sparse areas [citation:1].
Step 3: Wait for It to Dry
Let the product dry completely. The brand recommends waiting 10 to 20 minutes [citation:3]. Most testers found 8 to 10 minutes sufficient [citation:4][citation:8]. To check if it is ready, mouth the sounds “oooo” and “weee.” If the product crinkles and the edges curl up, it is ready to peel [citation:1].
Step 4: Peel It Off
Gently peel the film tint off starting from the inner corner of your lips. It should come off in one seamless strip if applied correctly [citation:3]. Sometimes it comes off in pieces; blot away lingering flecks with a tissue rather than picking them with your fingers [citation:1].
Step 5: Let It Set
Cosmetic chemist Rachel Johnson recommends letting the fresh color set for one to two minutes before drinking water or applying lip balm or gloss on top [citation:1]. This extra waiting time helps the pigment last longer.
How Long Does Sacheu Lip Stain Last?
The staying power of this lip stain is impressive. In Allure’s testing, the color lasted about 10 hours without fading [citation:4]. One editor reported applying it in the morning, then going to the gym, eating lunch, drinking a Diet Coke, and having a snack. Her lip line remained intact hours later with no reapplying necessary [citation:8].
The Wirecutter testers found the stain lasted between five and 10 hours for most testers. Brighter and deeper colors held on longer than neutral shades [citation:1].
Transfer-Proof Claims: True or False?
Sacheu Lip Stain Shades: What’s Available
The Sacheu lip stain comes in multiple shades to suit different preferences. The most popular shade is p-INKED, a vibrant mauve that makes lips pop without looking over the top [citation:8]. Other shades include Hey-zel, Clover, Muah-ve, and Ice Breaker [citation:3][citation:10].
The product is available in bundles. The Deep Bundle includes p-INKED, Hey-zel, and Clover shades [citation:3]. Each tube contains 0.12 fluid ounces of product [citation:5].
Expert Testing: What the Reviews Say
Beauty editors and consumers have mixed opinions about the Sacheu lip stain. Here is what they discovered.
Wirecutter Review (The New York Times)
Five Wirecutter staffers tested the product for three weeks. They consulted a dermatologist, a cosmetic chemist, and a professional makeup artist. Most testers did not like it enough to purchase it for themselves. However, they noted that the color lasted between five and 10 hours for most people [citation:1].
The main complaints were about the thick applicator. It is larger than a typical pencil, making it difficult to create precise lines, especially on thinner lips. Two testers struggled to get the pigment to last beyond an hour or two [citation:1].
Allure Review
Allure named the Sacheu lip stain the Best Peel-Off product in their lip liner stains roundup. Their tester gave it rave reviews, noting that it lasted 10 hours and survived the gym, lunch, and snacks [citation:4][citation:8]. They called it “fun, effective, and super-satisfying” [citation:8].
People Magazine Review
People’s tester put the stain to the test on girls’ nights out, vacations, and countless dinners. She confirmed that it truly does not budge. It survived a full night out without any reapplication. The color stayed vibrant even after washing her face [citation:6].
Common Application Issues and How to Fix Them
The Product Looks Patchy After Peeling
This happens when the initial application is uneven. Apply a generous, even layer. Re-dip the applicator to fill any sparse patches before the product dries [citation:1].
The Stain Fades Quickly
Two main factors cause premature fading. First, you may not have exfoliated your lips beforehand. Flaky skin prevents the stain from adhering evenly. Second, you may not have let the stain set after peeling. Wait one to two minutes before drinking or applying balm [citation:1].
The Applicator Is Too Big for Your Lips
For those with thinner lips, the doe-foot applicator can be challenging. Try using the product as an all-over stain rather than a precise liner. You can also apply it with a lip brush for more control [citation:1].
Can You Use Sacheu Lip Stain with Other Products?
Yes. Once the stain has set, you can apply lip balm, lip oil, or lip gloss on top. The brand sells Sacheu Sweet Balm separately for this purpose [citation:3]. The stain will not transfer onto your gloss applicator [citation:6].
Who Should Avoid This Product?
Do not use this product on damaged or broken skin [citation:5]. If you want to limit your use of polyvinyl alcohol, dermatologists recommend using products like this lip stain in moderation rather than every day or multiple times daily [citation:1].
Where to Buy Sacheu Lip Stain
The Sacheu Lip Liner STAY-N is available at several retailers. You can find it at Ulta Beauty, Revolve, Amazon, and the official Sacheu website. The price is approximately $14 per tube [citation:1][citation:3][citation:7].
