Understanding Nodular Acne: Causes, Symptoms, And Treatment

Acne is a common skin condition that affects millions of people worldwide, with various forms ranging from mild to severe. One particularly severe and persistent type of acne is nodular acne. Nodular acne is characterized by large, painful, inflamed lesions that develop deep within the skin. Understanding the causes, symptoms, and treatment options for nodular acne is crucial for effectively managing this condition and preventing potential complications. In this article, we delve into the world of nodular acne and shed light on the best practices for dealing with it.

How To Identify Nodular Acne?

A severe form of acne known as nodular acne is characterized by nodules, which are big, painful sores. These nodules are larger than usual zits and are located deep within the skin. Look for certain indicators, such as the presence of big, red, sensitive pimples without an obvious whitehead or blackhead, to determine whether you have nodular acne. These nodules can be touch-sensitive and frequently have a firm feel. They could be accompanied by localized edema and inflammation. On the face, neck, back, or chest, nodular acne can develop. Consult a dermatologist for an accurate diagnosis and treatment if you suspect nodular acne.

Causes Of Nodular Acne

Here are some potential causes and factors associated with nodular acne:
  • Hormonal fluctuations, particularly during puberty, menstruation, pregnancy, or menopause, can trigger the development of nodular acne. Androgens, such as testosterone, play a role in stimulating the sebaceous glands to produce more sebum, which can clog pores and lead to acne.
  • Propionibacterium acnes (P. acnes) is a bacterium commonly found on the skin. When excess sebum and dead skin cells accumulate in the pores, it provides an ideal environment for the growth of P. acnes. The bacteria can then trigger an immune response, leading to inflammation and the formation of nodules.
  • Acne, including nodular acne, can have a hereditary component. If your parents or close relatives have a history of severe acne, you may be more prone to developing nodular acne.
  • The development of nodular acne is significantly influenced by inflammation. The redness, swelling, and pain associated with nodular acne are caused by inflammation brought on by the immune system in response to bacterial overgrowth in the pores.
  • Certain medications, such as corticosteroids, lithium, and some antiseizure medications, can contribute to developing acne, including nodular acne, as a side effect.

Symptoms Of Nodular Acne

Here are the symptoms commonly associated with nodular acne:
  1. Inflammation: Significant inflammation often goes hand in hand with nodular acne. The impacted areas seem swollen, red, and tender to the touch. Beyond the nodule itself, the surrounding skin may also become inflamed.
  2. Pain and tenderness: The lesions of nodular acne are frequently unpleasant and irritating to the touch. The discomfort can be light to severe, and pressure or movement may worsen.
  3. Scarring: Nodular acne is more likely to result in scarring than less severe acne because of the depth and intensity of the inflammation. The appearance of the skin may be badly impacted by these scars, which may be permanent.
  4. Absence of surface breakouts: Nodular acne typically has fewer visible breakouts, such as blackheads or whiteheads, than other forms of acne. Instead, attention is directed toward the deep, agonizing nodules that develop beneath the skin.

It is important to consult a dermatologist for an accurate diagnosis and appropriate treatment if you suspect you may be experiencing nodular acne. 

How To Get Rid Of Nodular Acne?

Effectively managing nodular acne requires a comprehensive approach that combines professional guidance, lifestyle modifications, and targeted treatments.

Here are some treatment options commonly employed for nodular acne:

Prescription Medications

To lessen oil production, lessen inflammation, and avoid scarring, dermatologists may recommend oral drugs like isotretinoin. Antibiotics may also be used to treat inflammation and stop bacterial development.

Topical Treatments

Prescription-strength topical medications, including retinoids, benzoyl peroxide, and topical antibiotics, can help treat nodular acne by unclogging pores, reducing inflammation, and killing bacteria.

Intralesional Injections

Dermatologists may administer intralesional corticosteroid injections directly into the nodules to reduce inflammation and accelerate healing.

Professional Procedures

Certain procedures, like chemical peels, microdermabrasion, and laser therapy, can be used to improve the appearance of acne scars and enhance overall skin texture.

Skincare Routine

Establishing a moderate skin care program is essential to manage nodular acne. While excessive rubbing or picking at the skin must be avoided in order to prevent scarring, non-comedogenic cleansers and moisturizers can aid in preventing further irritation.

Dietary and Lifestyle Modifications

While diet alone does not cause nodular acne, some individuals may find that reducing their intake of high-glycemic foods and dairy products can improve their symptoms. Also, managing stress levels, regular exercise, and maintaining good hygiene practices can contribute to overall skin health.


In conclusion, nodular acne is a severe form of acne characterized by the presence of large, painful, and inflamed nodules beneath the skin’s surface. It is caused by a combination of factors, including excess sebum production, clogged pores, bacterial overgrowth, and inflammation.Nodular acne can have a significant impact on an individual’s self-esteem and quality of life, as the lesions are often stubborn and can leave behind scars. 

Treatment for nodular acne typically involves a comprehensive approach that may include topical medications, oral antibiotics, hormonal therapies, and isotretinoin. In some cases, dermatologists may also perform procedures such as corticosteroid injections or drainage of large nodules to alleviate pain and promote healing.
