Internal spine: why does it occur? How to relieve symptoms?

Although it is normal and can manifest itself in anyone, acne is seen as an imperfection in the skin that, in most cases, is a cause for shame and low self-esteem for those who have it.

Fortunately, there are several types of treatments to reduce the popular pimples and make the patient regain confidence in his appearance.

In general, these treatments vary according to the cause of acne, which may be due to unbalanced diet, use of cosmetics that cause oiliness, dehydration, hormonal changes, among other reasons that a doctor can evaluate.

So, understand in this article what causes an internal pimple and what are the ways to treat it properly to avoid skin blemishes or infections.


What is an internal spine?

It is classified as internal spine or nodule-cystic (classified as acne grade III) a type of acne considered more complex and more difficult to be eliminated, since it “hides” under the inner layer of the skin and takes longer to reach to the surface.

In general, it arises due to a hormonal imbalance and stress situations , in addition to  anxiety . For this reason, internal pimples are quite common throughout adolescence and during the menstrual period, since they are phases where sudden hormonal spikes and falls occur, causing the appearance of this type of pimple.

The internal spine usually causes inflammation and swelling. In addition, when touched, it usually causes intense and very uncomfortable pain.

Despite the suffering, it is important to understand that taking the necessary care (both at home and as indicated by a dermatologist) for the recommended period is the best way to eliminate the internal spine.

Thus, no attempt to end the internal spine more quickly, such as squeezing, cutting or puncturing is appropriate, because in addition to not being effective, it can aggravate the situation, in addition to infecting and even staining the skin.

How do internal spines form?

The internal spines, as well as the normal ones, are formed as a result of the obstruction of the sebaceous glands (located in the deepest layer of the skin) by a secretion called sebum.

This secretion is an oily substance that the sebaceous glands release as a way to moisturize and protect the skin from dryness. However, when there is an imbalance in the body (hormonal, nutritional, psychological) it ends up being produced in excess, causing the clogging of the pores

When this occurs, it causes an inflamed and painful lump, which gains the popular name of spine, which can be internal (when it does not show on the skin surface) or normal (when it is noticeable).

What can cause internal pimples?

Internal pimples are usually caused by hormonal changes, especially sex hormones, which are estrogen (female) and androgen (male).

In general, these hormones start to be produced during puberty, an important period that occurs during adolescence, which is why acne (of all types including intense) is more common at this stage.

However, even after this phase, already in adulthood, internal pimples may continue to appear and, in this case, are associated with psychological imbalances, such as stress and anxiety crises.

In addition to this motivation, the internal pimples at this stage can manifest due to an inadequate skin care routine (use of cosmetics that increase sebum production) and the excessive consumption of processed foods (especially those that are rich in sugars) and fats, as they cause inflammation of the sebaceous glands).

In the case of women specifically, internal pimples can also arise due to the beginning of the menstrual cycle, since there is an increase in hormones in the female body during this period.

Therefore, to find out the real cause of the internal spine, it is recommended to seek a general practitioner, who will assess the condition and refer you to the most appropriate professional to solve the problem.

How to care and treat?

It is important to clean the skin daily to prevent bacteria from causing complications in the region affected by the internal spine.

It is important to note that the best way to treat the internal spine is to discover its real cause, especially when it arises frequently. Therefore, it is always recommended to look for a dermatologist, who will assess the situation, make the diagnosis and prescribe the best treatment.

However, while waiting for the consultation, some precautions can be taken at home to help relieve symptoms that accompany the internal spine and also to avoid complications, such as:

  • Pain and inflammation – to reduce the pain caused by the internal spine, using a bag (or a cloth) with warm water on the spot can help, since the steam provided by the warm water promotes pore relaxation and reduces the presence of pus, which relieves pain and the inflammatory process in the lesion.
  • Swelling and redness – placing a small compress with ice under the inner spine for a few minutes (10 minutes) throughout the day, is a great way to deflate the lump due to the condition and decrease the redness, as the ice reduces blood flow in the region mitigating these symptoms.
  • Bacteria – To avoid the proliferation of bacteria that aggravate the condition of the internal spine, it is recommended to follow a daily skin cleaning routine. Therefore, specific products should be used for the condition and that do not cause any allergic reaction.

Can you pierce the internal spine?

It is extremely contraindicated by the Brazilian Society of Dermatology to pierce, squeeze or attack acne in some way (whether internal or not), because, in addition to being an ineffective action, it increases the chances of infections, spots and bleeding in the area.

Thus, the most correct thing to do is to adopt daily care to alleviate symptoms, clean the skin properly and follow the treatment prescribed by a dermatologist (if any).

Internal spine turned into a hard lump: what should I do?

When you have an internal spine, it is common that when you touch it, you feel a hard lump, since the pus that is inside it cannot get to the surface, which ends up causing this inflammation in the region.

In this case, it is essential to have patience, not to squeeze and perform actions that help to relieve the inflammation and facilitate the opening of the pores, so that this secretion comes out and the healing stage happens.

However, if this process (release of pus) is slow to occur, it may be necessary to perform a facial drainage in an appropriate clinic, under dermatological supervision, to prevent the evolution of acne and allergic reactions in the body.

How long does it take to get an internal spine out?

In an attempt to eliminate the internal spine faster many people try to squeeze it, but this attitude can make the situation worse.

In general, the internal spine usually disappears  after one week , as it is expected that, at the end of this period, the secretion will be released, which consequently reduces inflammation and swelling – this, of course, if all care is taken .

However, in some cases, the internal spine can be prolonged, being necessary to start a dermatological treatment indicated by the doctor.

How to deflate the inflamed internal spine?

Ointments, cosmetics and medications (with a medical prescription) that contain active ingredients capable of providing this effect can be used to facilitate the process of deflating the internal spine . For example:
