A new beauty trend sweeping social media may sound like a cheap and clever hack, but dermatologists are sounding serious alarms. The “Sharpie lip liner” trend, in which people use permanent markers like Sharpies to outline their lips before applying lipstick or gloss, has gone viral on platforms like TikTok — yet medical experts caution that the risks far outweigh any cost savings or viral clout.
What is the Sharpie Lip Liner Trend?

The trend is exactly what it sounds like: people take regular Sharpie permanent markers, typically in red or coral shades, and use them as lip liners by tracing the edges of their mouths. After applying the marker, they go over it with regular lip gloss or lipstick to create a bold, long-lasting lip look. Some users hype the affordability compared to high-priced lip liners, sparking a wave of imitators and curiosity across social media.
Dermatologists Sound the Warning

Experts are quick to caution that using Sharpies on skin, especially on lips, is not safe despite the viral appeal. Dr. Brooke Jeffy, a board-certified dermatologist, explained that permanent markers contain chemicals such as xylene, toluene, and urethane resin — substances commonly found in paint thinners and gasoline. These chemicals can be toxic if absorbed through the skin or ingested accidentally, which is a significant concern when applied so close to the mouth.
Health Risks of Using Sharpies on Lips
Regular use of Sharpie markers on lips can cause dryness, irritation, allergic reactions, or worse. The alcohol content in the markers can degrade the lips’ natural protective barrier, leading to chapped lips and inflammation. More worrisome is the unknown long-term effect of ingesting small amounts of the ink routinely as lips inevitably come into contact with saliva. Dermatologists emphasize that “non-toxic” labels on Sharpies only apply when used correctly on materials like paper, not on skin or near the mouth.
Cosmetic Drawbacks and Longevity Issues
Besides health hazards, Sharpies do not behave like traditional cosmetic lip liners. The ink is challenging to remove from skin and can linger visibly for days or weeks. Although Sharpies are marketed as smudge-proof on paper, they are not guaranteed to stay put on lips, often smearing or staining surrounding skin unevenly. This can create unflattering results contrary to the desired polished appearance.
Social Media Reaction and Continuing Popularity
Despite health warnings, some influencers and users have embraced the trend for its boldness and low cost, creating viral videos showcasing their Sharpie lip looks. Others report immediate harsh effects like burning sensations or dryness and advise against regular use. The disparity reveals a tension between DIY beauty hacks popularized online and medical advice grounded in safety and evidence.
Safer Alternatives to the Sharpie Hack
Dermatologists recommend sticking to cosmetic-grade lip liners and products tested for safety and formulated specifically for skin. These products avoid harmful chemical exposures and provide reliable, non-irritating, and easy-to-remove application. For those seeking long-lasting lip looks, multiple reputable brands offer affordable options well away from toxic markers intended for permanent ink on paper.
The Bottom Line: Beauty Shouldn’t Compromise Health
While the allure of viral trends is undeniable, medical experts urge consumers to prioritize health over fleeting social media fame. Using Sharpies on lips is neither a clever hack nor a safe cosmetic trick — it poses unnecessary risks with little rewarding payoff. As interest in beauty innovation grows, so too does the need for responsible choices supported by science and dermatological guidance.
In summary, the Sharpie lip liner trend has captured attention for its novelty and low cost, but dermatologists strongly advise against it due to harmful chemicals and potential health risks. For a safe, beautiful smile, investing in legitimate cosmetic products remains the smartest choice.
