What About Tap Water? Why It’s Not Suitable for Cleaning Your Eyelashes

What About Tap Water?

Tap water might be a convenient option for many daily tasks, but when it comes to cleaning your eyelashes, it's best to steer clear. Here’s why tap water isn’t the best choice for this delicate area, and what you should use instead.

1. Microbial Contamination

Presence of Pathogens

Tap water is not sterile and can harbor various microorganisms, including bacteria, fungi, and amoebas. A particularly dangerous one is Acanthamoeba, which can lead to serious eye infections like Acanthamoeba keratitis. This condition can cause severe pain, redness, and even vision loss if not treated promptly.

Risk of Infection

Using tap water to clean your eyelashes introduces these microorganisms to the sensitive eye area, increasing the risk of infections, inflammation, and other complications. The eye's delicate tissues are particularly vulnerable to these pathogens.

2. Chemical Irritants

Chlorine and Chloramines

Tap water is often disinfected with chlorine or chloramines, which can be harsh and irritating to the eyes and the sensitive skin around them. These chemicals are effective at killing pathogens in the water supply but can cause discomfort and dryness when they come into contact with your eyes.

Minerals and Impurities

Tap water can also contain dissolved minerals and impurities that might not be harmful when ingested but can irritate the skin and eyes. These substances can lead to allergic reactions or exacerbate existing skin conditions.

3. pH and Osmolarity Differences

pH Imbalance

The pH level of tap water can vary, and it might not be ideal for the sensitive skin around the eyes. A pH imbalance can disrupt the skin's natural barrier, leading to irritation and discomfort.


Tap water is not isotonic with bodily fluids, meaning it doesn't have the same concentration of solutes as the body's cells. This difference can cause osmotic stress, leading to discomfort and irritation when used to clean the eye area.

4. Specific Eye Hygiene Requirements

Specialized Products

There are products specifically designed for cleaning the eye area, such as sterile saline solutions, eyelid wipes, and micellar water. These products are formulated to be gentle, non-irritating, and effective at removing debris and makeup without introducing harmful pathogens or chemicals.

Hypoallergenic and pH-balanced

These specialized products are usually hypoallergenic and pH-balanced to match the natural environment of the eye area. This reduces the risk of irritation and infection, ensuring a safer and more comfortable experience.


Use Sterile Solutions

Opt for sterile saline or specially formulated eye cleansers to clean your eyelashes and the surrounding eye area. These products are designed to be safe and gentle.

Practice Good Hygiene

Always wash your hands thoroughly before touching your eyes or eyelashes to minimize the risk of introducing contaminants.

Follow Professional Advice

If you have specific eye conditions or concerns, consult with an eye care professional for personalized recommendations on maintaining eye hygiene.
