Does Mascara Cause Styes? The Science and Prevention

A stye is a common, often painful, red lump that forms on the eyelid, typically caused by a bacterial infection of an oil gland or hair follicle. Many people wonder if their daily beauty routine, particularly the use of mascara, plays a role in the development of these irritating bumps.

Understanding the Connection

Mascara itself does not inherently cause a stye, but its usage and maintenance can create conditions conducive to stye formation. These infections commonly arise from bacteria. This bacterium is naturally present on the skin and can easily be introduced to the delicate eye area through contaminated products or practices.

How Mascara Contributes to Styes

Mascara contributes to styes through bacterial contamination. Mascara wands pick up bacteria from the eyelashes, skin, or air, transferring them back into the tube and then directly onto the eye with subsequent applications. The dark, moist environment inside a mascara tube creates an ideal breeding ground for these bacteria, especially as the product ages.

Mascara can also lead to clogged glands, which are a direct cause of styes. If mascara flakes into the eye or is not thoroughly removed, it can block the tiny oil glands (Meibomian glands) or hair follicles along the eyelid. This blockage traps bacteria and creates an environment where they can multiply, leading to inflammation and infection.

Chemical irritants present in old or poor-quality mascara can inflame the eyelid. This irritation makes the eyelid more susceptible to infection by weakening its natural barrier.

Preventing Mascara-Related Styes

Good mascara hygiene minimizes stye risk. Mascara should be replaced every three to six months, or sooner if its texture, color, or smell changes. Sharing mascara is not recommended, as it can transfer bacteria between individuals.

Careful application techniques also help prevent styes. Apply mascara thoughtfully, avoiding the lash line itself if possible, and never apply mascara to the waterline (the inner rim of the eyelid). This prevents direct transfer of product and bacteria into sensitive glands. Avoiding excessive pumping of the mascara wand can also limit air exposure and bacterial growth within the tube.

Thorough yet gentle makeup removal every night is essential to prevent styes. Using a gentle, effective eye makeup remover can help melt away mascara without harsh rubbing, which can irritate the delicate skin around the eyes.

Maintaining general eye hygiene further reduces the risk of styes. Avoid touching your eyes unnecessarily, especially with unwashed hands, as this can introduce bacteria. Regularly cleaning reusable makeup brushes is also a good practice to prevent bacterial buildup.

Managing a Stye

If a stye develops, home care can help it resolve. Apply warm compresses to the affected eye several times a day for 5 to 15 minutes to reduce swelling and encourage drainage. Gently cleaning the eyelid with mild soap or a specialized eyelid cleanser can also be beneficial.

Avoid certain actions when a stye is present. Do not squeeze or try to pop a stye, as this can spread the infection or lead to more serious complications. Refrain from wearing eye makeup, especially mascara, and contact lenses until the stye has fully healed. This prevents further irritation and contamination of products.

Most styes resolve on their own, but medical attention may be necessary in some cases. Seek professional advice if a stye persists for more than a week or two, if pain or swelling worsens, if it affects your vision, or if the infection appears to be spreading. Recurring styes or those accompanied by fever also warrant a visit to an eye care specialist.
