Wearing kajal, also known as kohl or eyeliner, all day can have some potential side effects, especially if the product is not of high quality or if proper care is not taken during application. Here are some common side effects which you might not be aware of but need to keep in mind.
Eye irritation: Extended wear of kajal can lead to irritation, redness, and discomfort in the eyes.This can occur due to the ingredients in the kajal or due to particles from the product getting into the eyes.
Allergic reactions: Some individuals may be allergic to certain ingredients found in kajal. Prolonged exposure can lead to allergic reactions such as itching, swelling, or a rash around the eyes.
Dryness: Kajal can sometimes contain ingredients that may contribute to dryness around the eyes. Over time, this can lead to flakiness or dry patches on the eyelids or under the eyes.
Infection risk: If the kajal pencil or applicator is not properly sanitized or if the product is old and contaminated, there is a risk of bacterial or fungal infections. This can lead to conditions such as conjunctivitis (pink eye) or styes.
Smudging and smearing: Wearing kajal all day can result in smudging or smearing, especially in hot or humid weather. This can affect the appearance of the makeup and may require frequent touch-ups, leading to further irritation.

Clogged pores: Kajal applied to the waterline or inner rim of the eyes can potentially clog pores along the lash line. This may contribute to the formation of milia (tiny white bumps) or exacerbate existing skin issues around the eyes.
Vision disturbance: In some cases, kajal that smudges or migrates into the eyes can cause temporary blurring or disturbance of vision. This is usually mild and resolves once the product is removed.
Corneal abrasion: If kajal particles or the pencil tip itself come into contact with the surface of the eye, it can cause scratches or abrasions on the cornea. This can result in pain, sensitivity to light, and blurred vision.
Eyelash damage: Continuous application and removal of kajal can weaken eyelashes over time, leading to breakage or loss of lashes. This can result in sparse or uneven eyelashes, affecting the overall appearance of the eyes.
Increased tear production: Some individuals may experience increased tear production or watery eyes when wearing kajal for an extended period. This can be bothersome and may require frequent wiping or reapplication of the makeup.

Sensitivity to light: Prolonged exposure to kajal may make the eyes more sensitive to bright light or sunlight, leading to discomfort or squinting. This can be particularly problematic for individuals with light-colored eyes.
Skin discoloration: Certain kajal formulas may contain ingredients that can cause skin discoloration, especially if the product smudges or spreads onto the surrounding skin. This can result in dark circles or a grayish tint around the eyes.
Compromised eye health: Chronic use of kajal without proper removal can contribute to overall eye health issues, including dryness, irritation, and inflammation of the eyelids (blepharitis). These conditions can worsen over time if left untreated.
Risk of lead contamination: Traditional kajal formulas may contain lead, which poses a risk of lead poisoning, especially with prolonged use. While modern kajal products typically adhere to safety regulations, it’s essential to be cautious, especially with imported or homemade kajal preparations.
Psychological dependency: Some individuals may develop a psychological dependency on wearing kajal regularly, feeling self-conscious or incomplete without it. This can lead to excessive use and further exacerbate potential side effects.
To minimise the risk of these side effects, it’s important to choose high-quality kajal products, avoid sharing eye makeup with others, remove makeup before bedtime using a gentle cleanser, and give the eyes regular breaks from wearing makeup, especially if experiencing irritation or discomfort.
