How Long Does It Take a Styptic Pencil to Work?

A styptic pencil is a small, solid stick of medication that stops bleeding from minor cuts and scrapes. When used properly, a styptic pencil can effectively stop bleeding in just a few seconds. Most of the time, you will notice a change in ten to thirty seconds.

The working time of a styptic pencil also depends on the size and location of the cut. If you have a minor scrape, a styptic pencil will do its magic even in five seconds. However, more significant cuts require additional time, and sometimes you even have to repeat the process after a few minutes.

Most styptic pencils contain aluminum sulfate, which has astringent and antiseptic properties. It works by constricting the blood vessels and halting the flow of blood. So, how long does it take a styptic pencil to work? Let’s find out.

What Is Styptic Powder Made Of?

Styptic pencils contain aluminum salt compounds like aluminum sulfate, sodium aluminum sulfate, or potassium aluminum sulfate. Sometimes, styptic pencils contain these salts and chemicals in group forms known as alum.

Many people also ask “are styptic pencils safe?” so the list of ingredients lets us know that styptic pencils are, in fact, safe. You can easily apply them directly on your cuts and minor bruises. However, ingesting these chemicals or using them for cuts in the mouth or nasal cavity is not wise.

How to Use a Styptic Pencil

To use a styptic pencil, start by wetting the pencil’s tip with cool water. Then, apply gentle pressure to the wound with the pencil tip for 30 seconds or until the bleeding stops. You can reapply the styptic pencil every few minutes until you notice that the bleeding is stopped.

You must only use a styptic pencil on minor cuts or scratches. If you have a more significant cut still bleeding profusely, seek medical attention immediately.

While styptic pencils are safe, you must follow a few precautions to stay safe.

  • Clean the area around the scrap with soap and water. Cleaning will help eliminate dirt and bacteria that can further worsen the situation or cause infection.
  • Use some best quality styptic pencils for instant results.
  • Directly apply the styptic pencil to the bleeding wound. You should not rub the pencil on the wound, as it is unnecessary. Press it against the wound for a few seconds.
  • Rinse off the pencil after use and place it in a safe place.
  • Wash your hands before and after cleaning the wound and stopping the blood flow.
  • Finally, apply a bandage to the wound as soon as possible.

These simple steps can save you from further infection.

Can You Ingest a Styptic Pencil for Internal Wounds?

The active ingredient in a styptic pencil is usually alum, a natural astringent. Ingesting alum for treating internal cuts and wounds is wrong as alum can be dangerous. Some aluminum salts are even fatal for humans. There is even a concern that aluminum excess in the human body may lead to dementia or breast cancer. However, scientific proof is not enough to accept this concept.

If you cut any internal cavity, it is best to seek medical attention from a qualified doctor.

Tips for Getting Fast Results

If you have difficulty getting your styptic pencil to work, try a few things.

  • First, ensure that you are using enough pressure when applying the pencil to the wound.
  • Second, try wetting the pencil’s tip with cold water instead of room-temperature water. Cold water helps constrict the blood vessels more effectively.
  • Finally, seek medical attention if you still cannot get the bleeding to stop after several minutes.

How Long Do You Leave Styptic Powder On?

How long you should leave styptic powder depends on the situation of your cut. For example, if you have a small nick on your neck, you may only need to leave the styptic powder on for a minute or two. However, leaving the styptic powder on for up to ten minutes is better if you have a more severe cut.

Generally, it is best to leave the styptic powder on for longer rather than shorter. If the bleeding does not stop after a few minutes, keep applying styptic powder to the wound until it stops.

Do Styptic Pencils Hurt?

It is common to nick yourself while shaving, and a styptic pencil can provide quick relief. But does the use of a styptic pencil hurt?

Generally speaking, no. Applying a styptic pencil to a fresh cut causes little pain or irritation. You may feel a brief sting as the astringent chemicals in the pencil work to close up the wound. However, it will be over before you know it.

Many people find that the sting from a styptic pencil is much less painful than the cut itself. So if you are looking for a quick and easy way to stop the bleeding from a minor shaving injury, reach for a styptic pencil. It might not be the most pleasant experience, but it is better than walking around with a bloody face.
