From their easy-to-apply, long-lasting formulas to the just-bitten flush they add to your lips, it's no wonder lip stains and lip tints have been trending this year.

One lip stain in particular has taken over my TikTok For You page. It's from Sacheu Beauty. In fact, you may have seen these videos yourself, which feature users lining their lips with a dark lip product, then peeling it off in one satisfying strip to reveal perfectly applied liner.

The product was inspired by Sacheu Beauty founder Sarah Cheung's viral video, in which she admitted to using an eyebrow tint as lip liner because of it's staying power.

In response, the brand created the now-viral Lip Liner Stay-N, a peel-off lip liner stain that offers the staying power of a brow tint but is actually meant for your lips.

Spoiler alert: It's like nothing I've ever seen before.

What makes this lip stain different from others is that it's specifically designed to be used as a lip liner, whereas most stains only add a wash of color. Although you can totally use it that way, too.

As a beauty writer (and after months of putting it off), I knew I finally had to give the viral product a try. 

Why I like Sacheu Beauty's Lip Liner Stay-N

Because it's a stain, the product boasts a barely-there feel, perfect for those who don't love a heavy product. And unlike other lip pencils, I love that this one fades away gradually without looking unnatural.

While no lippie you apply yourself is going to last forever, the Lip Liner Stay-N can easily go up against any product marketed as only a lip pencil. Plus, it comes in seven flattering shades, from a rosy flush to a true nude.

If you've been wondering if this viral peel-off lip liner stain is worth the hype, I'm here to tell you that it is. But there are some hacks to using it! 

How to use the viral peel-off lip liner stain

Here are a few tips and tricks to make the most of Sacheu's Lip Liner Stay-N.

To start, exfoliating your lips is always a good idea. It can help remove any dead skin and ensure a smooth application.

The brand suggests leaving the stain on for 10 to 20 minutes. I recommend leaving it on for at least 20 minutes or more for the best color payoff. I've also found that the longer you leave it on, the longer it will stain.

Pro Tip: Don't be afraid to apply a lot of product, since an even and generous layer will ensure the best results.

After 20 minutes, the stain will have completely dried, which means it's time peel it off. Then, you can top it with your favorite lip gloss, lip oil, tinted lip balm, or lipstick.
