The author's induration - what is it and how is it treated?

A writer’s induration or stump is also known as an “author’s bump” or “nerd bump.” It is a callus that appears on one of the fingers of the other hand that experiences constant abrasion due to a pen or other writing instrument.

Is it possible to get rid of the hardening of the author?

Although it does not cause health problems, this hand is ugly and may be irritating. For these reasons, for example, people seek help to treat it to reduce or get rid of induration.

Fortunately, there are a wide variety of options you can try. Next, we will explain them in more detail.

Why does the author’s induration appear?

An article in the American Family Physician states that sprains are caused by a physiological reaction of the skin called hyperkeratosis. It is caused by constant pressure or friction on the skin caused by a special material.

The hardening of a writer is caused by the constant use of a writing instrument such as a pen, fountain pen, marker, or wax crayon. When pressure is applied to one finger – it can be the middle finger or the ring finger – a hard lump in the finger is formed, consisting of dead skin cells.

Its main function is to protect the lower layers of the skin that would otherwise become irritated. Although it is a harmless affliction, it causes discomfort and is not very beautiful. For this reason, the sufferer seeks solutions to minimize induration.

Wrinkle hardening occurs when pressure or abrasion is applied to the skin of a finger.
The hardening of the author is due to the abrasion caused by regular writing.

Recommended treatments for the author to cure

The hardening of the author cannot be completely removed surgically. As noted in the American Academy of Dermatology, most hardening disappears when the abrasion caused by the finger ceases. Some therapeutic options also accelerate their decline.

For the author’s induration, some approaches have been found to be effective. However, they do not provide immediate results and should be handled with patience to avoid further damage to the skin.


The first recommendation for an author to treat induration is to soak and peel it. According to information provided by the Mayo Clinic, this simple process softens the skin and removes the accumulated dead skin cells.

  • First, soak the hardener in warm water for ten minutes.
  • Then carefully scrape off the hardening with pumice or nail file. The purpose is to remove dead skin cells.
  • The treatment should be repeated every day until there is a noticeable improvement in the skin of the finger.


The American Academy of Dermatology recommends the addition of moisturizing products that also contain salicylic acid, ammonium lactate, and urea. These ingredients help soften the author’s induration and gradually break down dead skin cells.

Other useful products for moisturizing include:

  • aloe vera gel
  • coconut oil
  • sheavoi
  • castor oil
  • Vitamin E.
  • olive oil

Acetylsalicylic acid

Ideally, products prescribed by a dermatologist that contain salicylic acid should be used for curing. As an alternative or complementary treatment, you can try home treatment with aspirin, or acetylsalicylic acid.

According to a review by Clinical, Cosmetic and Investigational Dermatology, salicylic acid acts as a keratolytic agent and helps relieve skin problems.

  • For this home treatment, 3-5 aspirin tablets need to be crushed into a powder. 
  • Add a little water to the powder to make it a paste.
  • Add the paste to the hardener, rub gently and wrap a plastic wrap over the hardener for 10-15 minutes.
  • When the time has elapsed, remove the plastic, paste and rinse your finger.
  • Repeat the treatment every day until the induration has decreased.

Preventing author hardening

If you write regularly, it can be difficult to prevent the writer from hardening. However, there are some simple steps you can take to prevent this bump from occurring. Here are some key actions:

  • When typing, wear a cover on your finger. A thick patch or cotton glove can help protect your finger from abrasion caused by the writing instrument.
  • Get a pen handle. Another way to put a kind of barrier between the pen and your finger is to get a pen handle made of rubber or foam. It is attached to the pen. There are also pens with the pen handle pre-attached.
  • Choose a gel pen. When writing, such a pen requires less pressing of the pen and thus puts less pressure on the finger.
  • Relax your grip. It’s also good to remember not to press the pen too much when writing. Take breaks from writing and relax your hand.
Home care made with aspirin can help get rid of the hardening of the author.
Powdered aspirin tablets can help defeat the author’s induration. However, it would be better to use topical salicylic acid prescribed by your doctor.

Is it necessary to consult a dermatologist?

Because it is a harmless affliction, the author’s induration often disappears on its own without the need to be examined by a dermatologist. If the treatments mentioned earlier in this article do not work for sclerosis, it is a good idea to see a dermatologist. The expert is able to prescribe other effective forms of treatment, if necessary.

If there are signs of inflammation during curing, it is important to see a specialist. Redness, purulence, pain, inflammation, and bleeding may be signs of infection.
