What You'll Learn

Concretion risks
Mascara is a cosmetic product that enhances the eyelashes by adding volume and definition. However, sleeping with mascara on can lead to several issues, including concretions.
Concretions are solid masses that form underneath the eyelids. They occur when mascara is not properly removed and builds up over time. This can cause eye pain and irritation, and if left untreated, can lead to more severe conditions such as blindness.
In a case study, an elderly woman presented with constant eye pain and irritation. Upon examination, it was found that she had concretions beneath her eyelids due to improper mascara removal for 25 years. The concretions had the potential to become infected, which could have led to blindness. This illustrates the serious risks associated with failing to remove mascara properly and the potential long-term consequences.
The buildup of mascara can also clog the hair follicles of the eyelashes, disrupting their natural growth cycle. This can lead to reduced eyelash volume and increased brittleness, making the lashes prone to breakage. Additionally, the presence of mascara on the eyelashes can increase the risk of eye infections due to the buildup of bacteria.
To prevent concretions and other eye conditions, it is important to properly remove all traces of mascara and eye makeup before bed. This can be done using 100% cotton pads, Q-tips, or makeup remover wipes, followed by a gentle cleanser to ensure all remaining makeup is removed. Making this a part of your bedtime routine is crucial for maintaining eye health and preventing potential complications.

Eye conditions and infections
Mascara is a cosmetic product used to enhance the eyelashes by adding volume and definition. It is available in liquid, powder, or cream form and is made from various pigments, oils, waxes, preservatives, and emollients. While mascara can be beneficial for enhancing your eyelashes, sleeping with it on can lead to several eye conditions and infections.
One of the most common issues associated with sleeping in mascara is eye irritation. This can be caused by the mascara itself or by the bacteria that accumulates in the eye during sleep. The bacteria can lead to infections or styes, which are small, painful lumps that form on the edge of the eyelid or inside the eyelid. Additionally, the mascara can also cause clumping and falling out of eyelashes.
Another potential consequence of sleeping with mascara on is the formation of concretions, which are solid masses that form underneath the eyelids. These masses can cause eye pain and irritation, increasing the risk of blindness if left untreated. According to a case study, an elderly woman experienced constant eye pain and irritation due to concretions that had formed from improper mascara removal over 25 years.
Sleeping with mascara on can also increase the frequency of eye infections. This is because the mascara can trap oil, dirt, and bacteria against the skin, providing a breeding ground for bacterial growth. Additionally, the mascara can clog the hair follicles and oil glands on the eyelids, disrupting the natural growth cycle of eyelashes and leading to weakened, brittle lashes that are prone to breakage.
In some cases, individuals may experience allergic reactions to the prolonged exposure of mascara, resulting in redness, swelling, and itching of the eyes. While occasional slip-ups might not cause immediate damage, making it a habit can lead to long-term eye health issues. Therefore, it is essential to make removing all traces of eye makeup, including mascara, a part of your bedtime routine to maintain eye health and prevent infections and other eye conditions.

Clogged hair follicles
Mascara can clog the hair follicles of the eyelashes, disrupting the natural growth cycle and preventing new lashes from growing properly. This can reduce eyelash volume and make lashes more prone to breakage.
Folliculitis can be exacerbated by hot temperatures and sweating, which promote the colonisation of hair follicles by yeast and bacteria. Other causes include hyperkeratosis (excess dead skin) around hair follicles, which can be related to dandruff, psoriasis, scarring alopecia, or fungal infection. Oily skin can also promote inflammation and the growth of pathogens.
Signs of clogged hair follicles include small, inflamed bumps, similar to small pimples around the hairs. If left untreated, the areas of infection can become larger and more infected, with the skin becoming discoloured and scarred, and hair loss may occur. In rare cases, a serious infection called cellulitis can develop, which can spread to the blood and lymph nodes.
To prevent clogged hair follicles, regular cleansing is essential. This prevents the accumulation of oil, dirt, and debris on the scalp. Exfoliation with specialised scrubs or brushes can effectively remove dead skin cells and excess sebum. Apple cider vinegar rinses can help to balance the scalp's pH, dislodging buildup, and clarifying shampoos containing salicylic or glycolic acid can deeply cleanse the scalp and follicles.

Eyelash damage
Sleeping with mascara on can have several adverse effects on eyelash health. Mascara can clog the hair follicles of the eyelashes, disrupting the natural growth cycle and preventing new lashes from growing properly. This can reduce eyelash volume and make eyelashes more prone to breakage.
Over time, leftover mascara can weaken eyelashes, making them brittle and more likely to fall out. It can also cause clumping of the eyelashes, further contributing to lash loss. Additionally, the buildup of mascara on the lashes can attract bacteria, leading to a higher risk of eye infections and irritation.
Failing to remove mascara before sleep can also result in the formation of concretions, which are solid masses that develop underneath the eyelids. These masses can cause eye pain, irritation, and, in severe cases, can lead to blindness. Regular eye irritation can also increase the risk of rupturing the cornea, resulting in blurred vision.
To maintain eyelash health, it is crucial to make removing all traces of mascara and eye makeup part of your bedtime routine. Using 100% cotton pads or Q-tips with a gentle cleanser can effectively remove mascara without irritating the delicate eye area.

Allergic reactions
Sleeping with mascara on can cause a variety of issues, including allergic reactions. While makeup allergies are generally classified as type IV, the least severe type of allergic reaction, they can still cause significant discomfort. Common symptoms of a mascara allergy include watery eyes, swollen or irritated eyelids, itching, burning skin, and rashes with red bumps and blisters around the eyes.
Mascara contains a variety of ingredients that can trigger allergic reactions, including preservatives, dyes, and fragrances. Parabens, for example, are a group of preservatives that can be found in mascara and have been known to cause allergic reactions. Fragrances, which are added to mask the underlying scent of other ingredients, can also contain allergens such as alcohol, essential oils, and other potential irritants.
Some people may also be allergic to specific ingredients commonly found in mascara, such as propylene glycol, shellac, black iron oxide, and PPD. Black iron oxide, for example, may be contaminated with nickel, a common allergen. If you have sensitive skin or have reacted to certain ingredients in the past, you are more likely to experience an allergic reaction to mascara.
To determine if you are allergic to mascara, you can perform a patch test. Apply a small amount of the product to a discreet area of your skin, such as the inner arm, and wait for at least 24 hours to see if any allergic reactions occur. If you experience an allergic reaction to mascara, it is important to discontinue use and consult a dermatologist or eye specialist if symptoms persist or are severe.
To avoid allergic reactions, it is recommended to remove all traces of mascara and other makeup before sleeping. The accumulation of chemicals present in mascara can cause eye problems and expose the eye to opportunistic bacterial infections. Additionally, the fibers in some mascaras can fall into the eye, scratching the cornea and causing further irritation or infection.
