Skin growing under toenails is a condition known as hyponychium. It occurs when the skin just under the free edge of the nail, near the fingertip, thickens and overgrows. This can be caused by various factors, including fungal infections, psoriasis, and autoimmune conditions such as lupus. While the hyponychium typically acts as a barrier to protect the nail from germs and debris, its overgrowth can lead to discomfort, pain, and an increased risk of infection. Treatment options include antifungal medication, cuticle oil, and consulting a dermatologist for specialized care.

The hyponychium is the skin under the free edge of the nail
However, the hyponychium can sometimes overgrow and become thicker, which can make trimming nails painful. Pterygium inversum unguis (PIU) occurs when the hyponychium attaches to the underside of the nail as it grows. It is an uncommon condition but a common cause of skin overgrowth under the nail. Scientists don't fully understand PIU, but they know it can be present from birth or acquired later. The acquired form is most commonly associated with autoimmune conditions such as lupus but can also be triggered by external factors.
Nail psoriasis and fungal infections can also cause skin cells to accumulate under the nails. To treat overgrown hyponychium, some people apply cuticle oil to soften the thickened skin. It is important to consult a doctor instead of a nail technician, as nail technicians are not medically trained to treat nail conditions.
In addition to bleeding and pain when cut, breaking the skin under the nail with nail cutters can lead to infection. This infection can spread from one finger to another quite easily, especially if one has a habit of biting their nails. The excess skin on the toes can be even more problematic, as it can grow past the edge of the toenails and create a painful and frustrating type of ingrown nail.

Pterygium inversum unguis (PIU) is an uncommon cause of skin overgrowth
The hyponychium is the thick skin under the nail tip. It acts as a barrier to protect the nails from germs and debris. Sometimes, the hyponychium can overgrow and thicken, causing pain and increasing the risk of infection. This condition is known as Pterygium inversum unguis (PIU).
PIU is characterised by the abnormal adherence of the hyponychium to the underside of the nail plate, resulting in the obliteration of the distal nail groove. It is an uncommon condition, with only a few descriptions in the literature. However, it is a common cause of skin overgrowth under the fingernails. PIU may be present from birth or acquired later in life. Scientists have not yet fully understood this condition.
The acquired form of PIU is often associated with autoimmune conditions such as lupus. It can also be triggered by external factors, such as psoriasis, a skin condition characterised by rapid skin cell growth. In the hyponychium and nail bed, excessive skin cell growth can lead to scaling, buildup, and a condition called subungual hyperkeratosis. If left untreated, the skin can become very thick, leading to onycholysis, or the separation of the nail plate from the nail bed.
Additionally, certain nail practices can contribute to PIU. There have been reports of patients developing PIU after using gel polish. While the exact cause is unknown, it may be related to the chemicals in the gel polish or the application and removal process. Nail psoriasis and fungal infections can also cause skin cells to accumulate under the nails. Other risk factors include getting gel manicures, wearing acrylic nails, or biting your nails.
If you are experiencing skin overgrowth under your nails, it is recommended to consult a dermatologist, especially if there is bleeding, discolouration, or swelling. They can examine your nails and determine the best course of treatment.

Psoriasis is an autoimmune condition that can cause skin cells to grow excessively
The hyponychium is the skin just under the free edge of the nail, acting as a barrier to protect against germs and debris. Sometimes, the hyponychium can overgrow, leading to thickened skin under the nail. This condition is known as Pterygium inversum unguis (PIU), an uncommon but significant cause of skin overgrowth under the nail. While scientists have not fully understood PIU, it is often associated with autoimmune conditions, including lupus and psoriasis.
Psoriasis is an autoimmune condition that causes skin cells to grow excessively. It results from an over-reactive immune system, leading to inflammation and rapid skin cell growth. Typically, new skin cells take about a month to mature and replace old cells. However, with psoriasis, this process accelerates to just a few days, causing thick, scaly patches of skin. This rapid cell turnover can lead to skin plaques, rashes, and lesions.
The symptoms of psoriasis can vary from mild to severe and include itchy, cracked, and dry skin. It can also affect the nails, causing them to become pitted, cracked, or crumbly. In some cases, the skin under the nail thickens, leading to onycholysis, or the separation of the nail plate from the nail bed. This thickening of the skin under the nail, known as subungual hyperkeratosis, can be painful and increase the risk of infection.
Various treatments are available for managing psoriasis and its symptoms. These include light therapy, medications such as retinoids and immunosuppressants, and prescription skin creams. Early treatment is crucial in controlling symptoms and preventing additional complications. Additionally, home remedies such as daily oatmeal baths and avoiding alcohol may help alleviate symptoms.
While the exact causes of psoriasis are not fully understood, it is believed to have a genetic component, with a higher likelihood of occurrence if a family member has the condition. Environmental triggers, such as emotional stress, infections, skin injuries, and certain medications, can also contribute to the development and flare-ups of psoriasis.

Nail fungus can cause skin growth and discolouration
The hyponychium is the skin just under the free edge of the nail, located beyond the distal end of the nail bed. It acts as a protective barrier against germs and debris. Sometimes, the hyponychium can overgrow, leading to thickened skin under the nail. This condition, known as Pterygium inversum unguis (PIU), can cause discomfort and increase the risk of infection.
One possible cause of PIU is nail fungus, which can lead to skin growth and discolouration. Fungal nail infections typically start at the edge of the nail and can cause the nail to become thick, discoloured, crumbly, and brittle. The nail may turn white or yellow and break off, leading to pain and swelling of the surrounding skin.
Fungal nail infections are often caused by the same fungus that causes athlete's foot. This fungus thrives in warm, dark, and moist environments, making the feet particularly susceptible. Walking barefoot in communal areas, such as showers and gyms, can increase the risk of contracting the infection.
If you suspect a fungal nail infection, it is recommended to consult a pharmacist or healthcare professional. They can suggest appropriate treatments, such as antifungal nail medicine or tablets, to address the infection and alleviate symptoms. It is important to follow the treatment plan consistently for several months to effectively manage the condition.
In addition to medical treatments, maintaining proper nail care practices is crucial. Keeping the nails trimmed and filing them shorter can help manage PIU. Applying cuticle oil or moisturiser under the nails can also help soften the thickened skin and improve its appearance and comfort.

Treatment options include antifungal medication and cuticle oil
Toenail fungus is a common issue that can be treated in several ways. One option is to use antifungal medication, which can be taken orally or applied topically. Oral antifungal medications, such as terbinafine (Lamisil®), itraconazole (Sporanox®), or fluconazole (Diflucan®), are typically taken daily for several months and can be very effective in treating toenail fungus. However, they may have side effects and interact with other medications, so they are not suitable for everyone. Topical antifungal treatments, such as creams, gels, sprays, and patches, are also available over the counter or by prescription and can be applied directly to the affected area. These treatments may take longer to work and may not be as effective as oral medications, but they can still be useful for mild cases of toenail fungus.
In addition to antifungal medications, cuticle oil can be used to treat skin growing under the toenails. Cuticle oil helps to soften the thickened skin, making it easier to manage and reducing discomfort. It is important to note that cuticle oil does not treat the underlying fungal infection, so it should be used in conjunction with antifungal treatments for the best results.
While treating toenail fungus, it is recommended to practice good hygiene and foot care to reduce the chances of the fungus returning. This includes keeping the affected area clean and dry, trimming and thinning the nails, and wearing socks before putting on other clothing to reduce the spread of the fungus. In some cases, surgical treatment may be considered, especially if the infection is deep and has been present for a long time. However, this is a rare procedure and is typically only performed when other treatments have failed.
