Applying eyeliner to the waterline—the inner rim of the eyelid—has become a popular makeup technique for achieving a defined, dramatic look.
However, recent research suggests that this practice may pose significant risks to eye health.
A study conducted by Dr. Alison Ng at the University of Waterloo investigated how eyeliner particles migrate into the eye.
The findings revealed that within five minutes of application, 15% to 30% more particles entered the tear film when eyeliner was applied to the waterline compared to the outer lash line.
These particles can disrupt the tear film, leading to discomfort, dryness, and potential vision problems.
Challenging Common Beauty Practices
While many consider waterline eyeliner a harmless beauty trend, the research indicates otherwise.
The tear film—a thin layer protecting the eye—can be compromised by eyeliner particles, especially when applied to the inner eyelid.
This disruption can cause irritation and may lead to more severe issues, particularly for contact lens wearers.
Dr. Ng emphasizes that contact lens users are more likely to experience problems, as eyeliner particles can adhere to lenses, causing cloudiness and discomfort.
Additionally, the ingredients in eyeliner, such as waxes and oils, are designed to resist removal, making it challenging for the eye to clear these foreign substances.
Understanding the Tear Film and Its Importance
The tear film plays a crucial role in maintaining eye health by providing lubrication, reducing the risk of infection, and ensuring clear vision.
When compromised by foreign particles, its effectiveness diminishes, leading to symptoms like dryness, irritation, and blurred vision.
Applying eyeliner to the waterline introduces substances directly into this delicate system.
Over time, this can lead to chronic issues, especially for individuals with pre-existing conditions like dry eye syndrome or those who wear contact lenses.
Best Practices for Safe Eyeliner Application
To minimize risks associated with eyeliner use:
- Avoid the Waterline: Apply eyeliner to the outer lash line rather than the inner rim to reduce the chance of particle migration into the eye.
- Maintain Hygiene: Regularly sharpen pencil eyeliners to ensure a clean application. For twist-up eyeliners, trim the tip before each use to remove potential contaminants.
- Replace Old Products: Discard eye makeup every three months to prevent bacterial buildup, which can lead to infections.
- Remove Makeup Thoroughly: Always remove eye makeup before bed to prevent overnight irritation and potential complications.
Conclusion
While waterline eyeliner can enhance the eyes’ appearance, it’s essential to weigh the aesthetic benefits against potential health risks.
By adopting safer application techniques and maintaining proper hygiene, individuals can enjoy their makeup routines without compromising eye health.
