Nail Contact Dermatitis: Causes, Symptoms & Treatment Guide
Could your quest for the perfect manicure be harboring a hidden adversary? Contact dermatitis, a skin condition triggered by exposure to allergens or irritants, is becoming increasingly prevalent in the realm of nail care, turning a beauty ritual into a potential source of discomfort.
In 2019, the American Contact Dermatitis Society made a significant announcement, naming isobornyl acrylate as the "contact allergen of the year." This acrylic monomer, often employed in adhesives, has been flagged as a culprit behind a growing number of cases of allergic contact dermatitis (ACD). While acrylic nails are a known source, the issue extends beyond them, encompassing various products used in nail salons and at home. Clinicians are particularly challenged by this because routine tests may not immediately identify isobornyl acrylate as the irritant. Consumers and professional nail technicians (nail stylists) alike are potentially at risk, with occupational ACD being a growing concern.
The connection between acrylic and gel nails and contact dermatitis is well-documented. Studies reveal a link between these popular beauty treatments and dermatitis on the fingertips. Early signs of the condition frequently include itchiness in the nail bed, which may then evolve into dryness and peeling. The nature of the interaction during a professional manicure is also important. While a skilled nail technician should ensure that the brushes used for applying products rarely come into direct contact with your skin, accidental contact is inevitable, but the time to be concerned is when the brush is constantly on your skin.
The symptoms of a gel nail polish allergy can vary but typically include itchiness, redness, swelling, and blisters around the nails. For some, the reaction can be severe, with symptoms like skin lesions on the hands, lip swelling, or widespread skin lesions that indicate allergic contact dermatitis. One individual's experience with gel polish, after a year of use, led to the development of contact dermatitis under the nails, characterized by peeling skin and itchy fingertips/pads. Others have reported similar issues, with the condition disrupting the enjoyment of nail enhancements that had previously improved their lives.
The history of contact dermatitis related to nail cosmetics dates back decades. The first reported cases of allergic contact dermatitis from acrylates in manicure procedures were related to porcelain nails. It is important to understand that many ingredients within nail cosmetic products have the potential to sensitize the immune system, leading to contact dermatitis. These potential culprits include, but are not limited to, tosylamide, (meth)acrylates, and formaldehyde.
A clear temporal relationship between nail cosmetic procedures and an outbreak of eczematous symptoms on the hands, face, or other areas of the body can indicate contact dermatitis. In the professional sphere, contact dermatitis from gel nails can impact fitness for work, leading to sick leave. A case involving an office worker who developed severe fingertip dermatitis and onychodystrophy from preformed nails resulted in an extended absence from work before the root cause was identified. A specific case of contact dermatitis caused by methacrylate from shellac nail polish, a product of the nail brand CND, was highlighted in a 2017 report. The symptoms of nail contact dermatitis can manifest in different ways, including irritant contact dermatitis with nail plate yellowing, nail dystrophy, and cuticle destruction, as well as allergic contact dermatitis, which is marked by a distinctive reaction on multiple fingernails. While the risk of skin cancer from new generations of acrylic gel manicures appears negligible, regular use can still lead to contact dermatitis, as well as brittle and thin nails.

Contact dermatitis is fundamentally a skin reaction that occurs when you touch a substance that either irritates your skin or to which you are allergic. The resulting rash can be itchy and uncomfortable. Avoiding the cause of the reaction is key to preventing recurrence. Trim your nails to avoid scratching which could lead to further complications.

The information provided highlights that (meth)acrylates are a common cause of allergic contact dermatitis (ACD). These substances are found in a wide range of products including industrial, consumer, medical, dental, cosmetic, and aesthetic products, especially nail cosmetics. The differential diagnosis for dermatitis affecting the nail folds includes psoriasis, tinea manuum, irritant contact dermatitis, and allergic contact dermatitis. Diagnosis of allergic contact dermatitis is confirmed by patch testing; physicians should refer patients who use or work with nail products for testing if they present with dermatitis. Furthermore, understanding the causes, symptoms, and treatment options is crucial in managing and preventing contact dermatitis.
The implications of contact dermatitis go beyond aesthetic concerns. The condition can profoundly affect individuals, potentially causing significant distress and impacting their ability to work. In certain instances, the severity of the reaction can lead to significant medical issues, indicating the importance of early identification and management. Awareness of contact dermatitis and the agents that cause it is vital for consumers, nail technicians, and healthcare professionals alike. This knowledge allows for informed decisions, preventive measures, and effective treatment approaches to minimize the impact of this often-frustrating skin condition.
