The skin growing under your nails is known as the hyponychium. It is the tissue located under the free edge of the nail, acting as a barrier to prevent pathogenic bacteria from entering the finger. The hyponychium contains white blood cells to help prevent infection. However, it can sometimes overgrow, leading to thickened skin that may be aesthetically displeasing and painful to trim. This overgrowth can occur due to various factors, including nail psoriasis, fungal infections, genetic predisposition, and wearing long nails with gel or acrylic treatments for extended periods. Treatment options include antifungal medication, cuticle oil, and, in severe cases, consultation with a dermatologist.

Hyponychium overgrowth causes
The hyponychium is the tissue under the free edge of the nail. It acts as a seal to prevent pathogenic bacteria from entering the finger. The skin in this region contains white blood cells to help prevent infection.
The hyponychium can sometimes overgrow and thicken, causing discomfort and increasing the risk of infection. This overgrowth is called subungual hyperkeratosis. Hyponychium overgrowth can be caused by several factors:
Nail Enhancements
The use of nail enhancements, such as gel or acrylic nails, can contribute to hyponychium overgrowth. The solid and less flexible structure of these enhancements can limit the natural flexing or movement of the nail. As a result, the skin underneath the free edge that forms the hyponychium may not release itself naturally as the nail grows, leading to overgrowth.
Genetics
For some individuals, hyponychium overgrowth may be influenced by genetic factors. It could be a natural tendency for their hyponychium to attach to the underside of the nail as it grows.
Contact Dermatitis
Contact dermatitis, or an allergic reaction to certain substances, can also trigger hyponychium overgrowth. This may be related to the chemicals used in gel manicures or other nail treatments.
Nail Injury
Physical trauma to the nail, such as an injury, can disrupt the natural growth and release of the hyponychium, leading to overgrowth.
Nail Psoriasis and Fungal Infections
Nail psoriasis and fungal infections can cause skin cells in the hyponychium to grow excessively, resulting in scaling and buildup. This can lead to further complications such as onycholysis, which is the separation of the nail plate from the nail bed.
It is important to consult a dermatologist to determine the specific cause of hyponychium overgrowth and receive appropriate treatment.

Treatment options
The skin growing under your nails is called the hyponychium. It is the tissue just under the free edge of your nail, located beyond the distal end of your nail bed, near your fingertip. The hyponychium acts as a barrier to protect your nail from germs, debris, and pathogenic bacteria.
The hyponychium can sometimes overgrow and thicken, which can be uncomfortable and unsightly. Here are some treatment options to manage and reduce overgrown hyponychium:
- Cuticle Remover: Using a cuticle remover can help soften and reduce the thickened skin. It is important to gently push back the skin after showering, using a cuticle pusher or orange stick instead of cutting the skin.
- Cuticle Oil: Applying cuticle oil can help soften the thickened skin. It is recommended to use the oil on the hyponychium and gently push it back.
- Builder Gel: If you regularly get gel manicures, switching to builder gel, also known as BIAB nails, can help. This product adds a layer to the nail and is considered safer than regular gel manicures. It provides support and can reduce the elongated hyponychium.
- Nail Trimming and Filing: Keeping your nails short can help manage overgrown hyponychium. Cutting your nails as short as possible and then filing or trimming them shorter over time can help shrink the skin.
- Moisturizing: Keeping your nails and cuticles moisturized can help soften the skin. This can be done by applying oil or soaking your fingers in warm water before gently pushing back the skin.
- Medical Treatment: If the overgrown hyponychium is caused by a fungal infection or nail psoriasis, medical treatment may be necessary. Consult a dermatologist who can prescribe antifungal medication or topical corticosteroids to manage the condition.

Skin conditions and diseases
The skin growing under the nails is called the hyponychium. It acts as a barrier to prevent germs, debris, and pathogenic bacteria from entering the finger. The skin in this region contains white blood cells to help prevent infection. However, the hyponychium can sometimes overgrow and become thicker, which can be painful and increase the risk of infection. This can be caused by:
- The hyponychium attaching to the underside of the nail as it grows
- Genetic factors
- Wearing nails long with gel or acrylic nails for too long
- Contact dermatitis
- Nail injury
- Nail psoriasis
- Fungal infections
To treat overgrown hyponychium, you can try using a cuticle remover or cuticle oil to soften the thickened skin. It is important to note that you should consult a doctor instead of a nail technician, as they are medically trained to treat nail conditions.
In addition to hyponychium, there are several other skin conditions and diseases that can affect the nails, including:
Paronychia
Paronychia is a bacterial nail infection that can occur when bacteria enter broken skin near the cuticle and nail fold. Symptoms include pain, swelling, and tenderness around the nail, as well as redness and warmth of the skin. Pus may also build up under the skin, leading to a white to yellow, pus-filled abscess. Treatment for paronychia typically involves antibiotics and drainage of the abscess, if necessary.
Pitting
Pitting is a condition where dents in the nails appear, which may indicate an underlying disease affecting the entire body.
Yellow Nail Syndrome
Yellow Nail Syndrome is characterized by yellow nails that have thickened and stopped growing. It can be caused by wearing red nail polish without a base coat or smoking. However, it can also indicate underlying health issues such as lung disease or rheumatoid arthritis.
Beau Lines
Beau Lines are deep grooves or gaps that run across the width of the nail, indicating that something has slowed or stopped nail growth temporarily. This can be caused by a fever, injury, chemotherapy, or major stress.
Onychogryphosis
Onychogryphosis, or Ram's horn nails, is a condition where the nails thicken and overgrow. It can be genetic or associated with diseases such as psoriasis, ichthyosis, or circulation problems.
Koilonychia
Koilonychia, or spoon-shaped nails, is a condition where the nails become thin and dip down in the middle. It is often associated with iron deficiency, which can be caused by various factors, including high altitude.
While changes to your nails do not always indicate a disease, it is important to consult a board-certified dermatologist if you notice any unusual or persistent alterations. They can provide an accurate diagnosis and determine if further medical testing is required.

Nail injuries
The hyponychium is the skin just under the free edge of your nail. It acts as a barrier to prevent germs, debris, and pathogenic bacteria from getting under your nails. The skin in this region contains white blood cells to help prevent infection.
If the nail is torn or jagged, it should be trimmed to avoid further injury. If the nail lifts off the nail bed, it may be most comfortable to replace the nail and hold it in place with a bandage. Nails will not reattach to the nail bed after separation, but a new nail will usually regrow slowly. If blood under the nail occupies more than half of the nail area, a physician should evaluate the finger, as it could indicate a bone fracture or tissue tear.
For more serious nail injuries, such as a nail bed avulsion, where the nail and part of the nail bed are pulled away from the finger, urgent care or an emergency room visit is necessary. The nail and finger or toe will usually be numbed with medicine before treatment. If there is a large bruise, a small hole may be created in the nail to drain blood and fluid and relieve pressure and pain. If the bone is broken or the bruise is very large, the nail may need to be removed, and the nail bed repaired. Antibiotics may be prescribed to prevent infection.

Preventing skin growth
The skin growing under your nails is called the hyponychium. It is the tissue under the free edge of the nail, acting as a seal to prevent pathogenic bacteria from entering the finger. While the hyponychium is beneficial in safeguarding the nail, overgrowth can occur, leading to discomfort and aesthetic concerns.
To prevent skin growth under your nails, also known as Pterygium inversum unguis (PIU), it is important to understand the underlying causes, which can vary from person to person. Here are some preventive measures to address this condition:
Maintain Proper Nail Care Habits
The hyponychium can attach to the underside of the nail as it grows, leading to PIU. To prevent this, it is crucial to maintain short nails and avoid wearing them too long, especially with gel or acrylic manicures. Taking breaks between manicures and opting for nail-friendly alternatives like builder gel or BIAB nails can help reduce the risk of skin overgrowth.
Address Underlying Medical Conditions
Certain medical conditions, such as nail psoriasis and fungal infections, can cause skin overgrowth under the nails. If you suspect nail psoriasis, consult a dermatologist for proper treatment, which may include topical applications or oral medications. For fungal infections, antifungal medication, either topical or oral, can be effective.
Soak and Gently Push Back the Hyponychium
Soaking your nails in warm water and then gently pushing back the hyponychium with a cuticle pusher can help manage skin growth. It is important to ensure that the skin is softened before pushing it back, and to be cautious not to push too hard or too far. This method can help "train" the hyponychium back, reducing its growth.
Use Cuticle Removers and Oils
Applying cuticle remover or cuticle oil to the hyponychium can help soften the thickened skin and make it easier to manage. Put the oil on the hyponychium and gently push it back, especially after a shower when the skin is more softened. This can help prevent further growth and improve the appearance of the nails.
Consult a Dermatologist
If you are unsure about the cause of skin growth under your nails, it is always best to consult a dermatologist. They can examine your nails and determine the most appropriate treatment based on your specific condition. Nail technicians are not medically trained to treat nail conditions, so seeking professional medical advice is crucial.
