If you love the look of longer, fuller lashes, eyelash extensions can feel like a beauty game-changer. They add drama to your eyes and save time in your daily routine, but with any beauty treatment, you need to consider their larger effect. One common concern is whether eyelash extensions can lead to blepharitis—a condition affecting the eyelids that’s one of the main causes of dry eye.
Yes, eyelash extensions can cause blepharitis. While these beauty enhancements can elevate your lash game, they can also introduce risks if not handled correctly. You don’t have to give up fuller lashes to enjoy comfortable vision, but they may require some extra attention to keep your eyes healthy.
What Is Blepharitis?
Blepharitis is a common eye condition that affects the edges of your eyelids. It often occurs when the tiny oil glands near the base of your lashes become clogged, leading to irritation and inflammation.
The most noticeable symptoms of blepharitis include:
- Redness around the eyelids
- Itching or burning sensations
- Excessive watering
- Crusting or flaking at the lash line
- A gritty feeling in the eyes
- Sensitivity to light
- Dry eye
There are 2 main types to look out for:
- Anterior Blepharitis: Affects the outer part of the eyelid where your eyelashes are attached and is typically caused by bacteria build-up or excessive dandruff blocking your glands.
- Posterior Blepharitis: Affects the inner edge of the eyelid and is usually linked to issues with the meibomian glands. Skin issues such as rosacea and dermatitis are closely linked to this type.
Blepharitis shares many symptoms with other common eye conditions or can be the root cause of problems such as styes, chalazion, and damaged corneas. Your optometrist can determine what’s causing your inflammation during an eye exam and get you on the path to relief.
How Eyelash Extensions Can Cause Blepharitis
Many people use eyelash extensions safely and without issue. Similarly, some people who develop blepharitis have never used extensions. While eyelash extensions aren’t a direct cause of something like blepharitis, improper application or poor aftercare can increase the risk of developing it.
Here’s how fake eyelashes can lead to real discomfort:
- Adhesive & irritation: The adhesive used to attach extensions often contains chemicals that can irritate the eyes. For some, this can lead to allergic reactions or inflammation that contributes to blepharitis.
- Difficulty maintaining hygiene: Extensions can make it challenging to clean the eyelid area properly. This may create an environment where oil, dead skin, and debris build-up, increasing the likelihood of bacterial growth.
- Debris build-up: The combination of extensions and leftover makeup or natural oils can quickly clog the delicate glands along your lash line. Over time, this build-up can aggravate blepharitis symptoms.

Caring for Your Extensions & Your Eyes
Eyelash extensions are a popular beauty treatment that uses synthetic, silk, or mink fibres applied to your natural lashes using a semi-permanent adhesive. Unlike temporary lashes which are attached to your eyelid, extensions attach directly to your natural lashes, so they affect your eyes differently. Some types of extensions include:
- Classic extensions: A single extension applied to each natural lash for a subtle, enhanced look.
- Volume extensions: Fans of multiple lightweight lashes applied to create a fuller effect.
- Hybrid extensions: A mix of classic and volume extensions for a textured, dramatic appearance.
Different types of extensions require careful upkeep to maintain their look and, perhaps more importantly for people prone to irritation, prevent complications. Here are some proper precautions to help you enjoy your eyelash extensions without compromising eye health:
Choose a Reputable Technician
Ensure your lash technician is certified and follows high hygiene standards. Look for online reviews or request recommendations from trusted sources.
Request a list of the ingredients in the adhesive. Avoid adhesives containing formaldehyde, as it’s a toxin that can cause allergic reactions and skin irritation. If you’re allergic to latex, confirm it’s not included in the ingredients. Ensure your technician uses surgical-grade glue, not nail glue—using nail glue is a serious red flag.
Do a Patch Test
Always ask for a patch test before your initial appointment. This will help assess your sensitivity to the adhesive before committing to the full application. Certain people with skin conditions shouldn’t get eyelash extensions without consulting their doctor first.
Practice Proper Cleaning Techniques
Invest in a gentle, lash-safe cleanser designed for extensions. These products can efficiently remove dirt and oil without harming the adhesive. Avoid oil-based cleansers, which can cause extensions to detach prematurely.
Take Regular Breaks
Your natural lashes need time to recover. Consider taking breaks between extension appointments to avoid continuous strain on your lashes and eyelids.
When Should You See Your Doctor?
Blepharitis is a chronic condition, but many people are able to manage it by focusing on good eyelid hygiene. If redness, swelling, itching, or crusting on the lash line persists despite your best efforts, it’s time to speak with an expert.
An optometrist or ophthalmologist can properly diagnose and recommend treatments to manage blepharitis. Early intervention is key to preventing more serious complications such as dry eye.
Some common treatment methods include:
- Warm compresses: These can help loosen crusts and unclog blocked glands.
- Medicated cleansers: Specialized eyelid wipes designed to soothe inflammation.
- Antibiotics: In severe cases, prescription eye drops or ointments can tackle bacterial growth.
- Eyelid debridement: Treatments such as ZEST gently exfoliate eyelids to remove bacteria, debris, oil, and residue from the eyelids.
