Nail Lacquer-Induced Dermatitis

Nail lacquer-induced dermatitis, also known as nail polish allergy, is a type of allergic contact dermatitis. It transpires when the skin reacts adversely to certain ingredients in nail polish or nail lacquer. These ingredients, termed allergens, can trigger an immune response, leading to redness, itching, and inflammation of the skin.

Nail lacquers encompass a variety of chemicals that may induce dermatitis. Key allergens often include substances like formaldehyde, toluene, and dibutyl phthalate. These chemicals are primarily used to improve the lacquer’s longevity, shine, and drying speed, but can instigate skin reactions in sensitive individuals.

Types of Nail Lacquer-Induced Dermatitis

1. Allergic Contact Dermatitis: Allergic contact dermatitis is a common type of nail lacquer-induced dermatitis. It occurs when the immune system mistakenly identifies certain chemicals present in the nail lacquer as harmful substances. The body then triggers an allergic reaction, causing skin inflammation and discomfort.
2. Irritant Contact Dermatitis: Irritant contact dermatitis is another form of nail lacquer-induced dermatitis. Unlike allergic contact dermatitis, this condition is not triggered by an immune response. Instead, it results from direct contact with harsh chemicals in nail lacquers, leading to skin irritation and redness.

Causes

Potential causes

1. Ingredient Sensitivity: A common cause of nail lacquer-induced dermatitis is sensitivity to the ingredients in nail polish. Formaldehyde, toluene, and dibutyl phthalate are frequent culprits, causing redness, itchiness, and swelling around the nails.
2. Allergic Reaction: The body’s immune system may mistake some nail lacquer components as harmful, leading to an allergic reaction. This often results in dermatitis.
3. Frequent Use: Applying nail lacquer frequently increases your exposure to potential irritants, raising the likelihood of developing dermatitis.
4. Non-Removal of Old Polish: Leaving old polish on for an extended period can cause dermatitis, especially when a fresh layer is applied over it.
5. Incorrect Removal: If nail lacquer is incorrectly or roughly removed, it can damage the nail bed and surrounding skin, leading to dermatitis.
6. Use of Cheap Brands: Lower-priced nail lacquers often contain high levels of allergenic substances, heightening the risk of dermatitis.
7. Chemical Interaction: Some nail lacquer ingredients may react with substances you touch daily, causing a chemical-induced dermatitis.
8. Contact with Cuticle: Dermatitis can occur if the lacquer comes in contact with the cuticle or skin around the nail.
9. Use of Nail Hardeners: Some nail hardeners contain high levels of formaldehyde, a potential irritant causing dermatitis.
10. Nail Biting: Biting nails coated with lacquer can lead to oral dermatitis and rashes around the mouth.
11. Lack of Protective Gloves: Failing to wear protective gloves while performing household chores can exacerbate dermatitis from nail lacquer.
12. Nail Salon Practices: Unhygienic practices or use of old lacquer at nail salons can increase dermatitis risk.
13. Exposure to Water: Frequent or prolonged water exposure can deteriorate the nail lacquer and irritate the skin.
14. Acetone Use: Acetone, often used for nail lacquer removal, can cause skin dryness and dermatitis.
15. Artificial Nails: Artificial nails, usually coated with lacquer, can trap moisture and irritants, leading to dermatitis.
16. Shared Nail Lacquer: Sharing nail lacquer can introduce foreign substances and potential allergens, causing dermatitis.
17. Pre-existing Skin Conditions: Individuals with pre-existing skin conditions like eczema or psoriasis are more prone to nail lacquer-induced dermatitis.
18. UV-cured Lacquers: Some lacquers cure under UV light, which may cause a reaction leading to dermatitis.
19. Nail Lacquer Fumes: Inhaling nail lacquer fumes can cause respiratory and skin irritation, resulting in dermatitis.
20. Exposure to Heat: Heat can alter the nail lacquer’s chemical structure, increasing its irritability.
21. Nail Lacquer Thinner Use: Nail lacquer thinners, if spilled on the skin, can cause dermatitis.
22. Use of Metallic Polishes: Metallic nail polishes often contain allergenic compounds that can cause dermatitis.
23. Nail Extensions: Nail extensions often involve lacquers and glues that can irritate the skin and cause dermatitis.
24. Non-compliance to Patch Testing: Ignoring a patch test before trying a new lacquer can result in unexpected dermatitis.
25. Genetic Predisposition: Individuals with a genetic predisposition to allergies may experience dermatitis after using nail lacquer.
26. Incorrect Nail Lacquer Storage: Storing nail lacquer in inappropriate conditions can change its formulation, increasing the risk of dermatitis.
27. Nail Filing: Nail filing can spread lacquer dust on the skin, causing irritation and dermatitis.
28. Habitual Nail-picking: Picking at the lacquer can lead to nail damage and resultant dermatitis.
29. Exposure to Cold: Cold conditions can make skin dry and more susceptible to dermatitis caused by nail lacquer.
30. Use of Nail Art Pens: Nail art pens contain concentrated lacquer, which can be more irritant and cause dermatitis.

Symptoms

Symptoms of nail lacquer-induced dermatitis.

1. Redness: One of the initial symptoms you may notice is red, irritated skin around your nails. This dermatitis symptom occurs due to your skin reacting to a chemical irritant present in the nail lacquer.
2. Itching: Itching or pruritus is a common symptom associated with this dermatological condition. If you’re frequently scratching the skin around your nails, it might be time to rethink your nail lacquer.
3. Swelling: The skin around your nails or even your fingers may swell due to this allergic reaction. Swelling is an indication that your body is trying to fight off an irritant.
4. Skin Lesions: Lesions or blisters may form on the skin. This occurs when the dermatitis advances without proper treatment.
5. Dry, Flaky Skin: Your skin might become excessively dry and start to flake off, adding an uncomfortable and aesthetically displeasing aspect to the condition.
6. Pain: Pain or tenderness around the nails is another sign of nail lacquer-induced dermatitis. If it hurts to touch your fingers, it might be an indication of this condition.
7. Skin Discoloration: You may notice changes in your skin color. The area around your nails might become darker or lighter due to the inflammation.
8. Oozing Blisters: Advanced stages of this condition might cause the blisters to ooze. It’s vital to avoid scratching to prevent infection.
9. Cracked Skin: Prolonged exposure to the allergen can result in your skin becoming rough and cracked. This can make everyday tasks painful.
10. Burning Sensation: You might experience a burning sensation around your nails, which is an acute reaction to the chemical irritants in the nail lacquer.
11. Rash: A rash extending from your nails to other parts of your hand may appear. This symptom shows that the condition is spreading.
12. Peeling Skin: In severe cases, the skin might start peeling off, causing further discomfort.
13. Thickened Skin: Chronic nail lacquer-induced dermatitis can cause the skin around your nails to thicken. This is a result of your skin’s attempt to protect itself.
14. Nail Discoloration: While this condition primarily affects the skin, it can also cause your nails to change color.
15. Changes in Nail Texture: In addition to color changes, your nails may become rough or pitted due to the irritation.
16. Sensitivity to Heat/Cold: You might find your fingers becoming more sensitive to temperature changes, adding another level of discomfort.
17. Nail Deformity: If untreated, dermatitis can lead to permanent nail deformities, such as ridges or bumps on your nails.
18. Joint Pain: While less common, some people may experience joint pain in the fingers as the dermatitis progresses.
19. The feeling of Tightness: The skin around your nails may feel tight, further limiting your ability to move your fingers freely.
20. Sleep Disturbances: The discomfort and itching may interfere with your sleep, leading to insomnia or other sleep disturbances.
