What is Acne?

Definition of acne

Acne is a common skin condition characterized by the appearance of pimples, blackheads, whiteheads, cysts, and nodules. These skin lesions occur when the hair follicles in the skin become clogged with oil, dead skin cells, and bacteria. It commonly affects teenagers but can also occur in adults. Acne can occur on the face, neck, chest, back, and shoulders.

Common types of acne

There are several types of acne, each with its own characteristics. The most common types include:

  1. Whiteheads: These are small, flesh-colored bumps that are caused by clogged hair follicles. The trapped sebum and dead skin cells are not exposed to the air, which prevents them from oxidizing and turning black.

  2. Blackheads: Similar to whiteheads, blackheads are also clogged hair follicles. However, the trapped sebum and dead skin cells are exposed to the air, causing them to oxidize and turn black.

  3. Papules: These are small, raised, red bumps on the skin that are typically tender to touch. They occur when the hair follicles become inflamed due to excess oil and bacteria.

  4. Pustules: Pustules are similar to papules but are filled with pus. They appear as red bumps with a white or yellow center.

  5. Nodules: Nodules are larger, solid bumps beneath the surface of the skin. They are painful and occur when the hair follicles become infected and inflamed.

  6. Cysts: Cysts are deep, pus-filled bumps that are larger and more painful than pustules. They can cause scarring and require medical treatment.

Acne prevalence

Acne is a very common skin condition, affecting millions of people worldwide. It is estimated that approximately 85% of people experience acne at some point in their lives, with the condition being more prevalent in teenagers and young adults. However, acne can also occur in adults in their 30s, 40s, and beyond. It affects people of all genders, ethnicities, and skin types.

Causes of Acne

Hormonal factors

One of the main causes of acne is hormonal fluctuations, particularly during puberty. During this time, the body produces higher levels of androgens, which stimulate the sebaceous glands to produce more oil. This excess oil can clog the hair follicles, leading to acne breakouts. Hormonal changes associated with the menstrual cycle and pregnancy can also trigger acne in women.

Excessive oil production

Excessive oil production, also known as sebum, can contribute to the development of acne. When the sebaceous glands produce too much oil, it can mix with dead skin cells and bacteria, leading to clogged pores and acne breakouts.

Clogged pores

When dead skin cells are not shed properly, they can accumulate and mix with sebum, causing the pores to become clogged. This creates an ideal environment for acne-causing bacteria to thrive and leads to the formation of blackheads and whiteheads.


Acne is commonly associated with the presence of a bacterium called Propionibacterium acnes. This bacterium is naturally present on the skin but can multiply rapidly in the presence of excess oil and clogged pores. When the bacteria multiply, they cause inflammation and contribute to the development of acne lesions.


Inflammation plays a significant role in acne development and progression. When the hair follicles become clogged, the immune system responds by sending white blood cells to fight off the bacteria. This immune response leads to inflammation, redness, and swelling associated with acne.

Dietary factors

Although the relationship between diet and acne is complex and varies from person to person, certain dietary factors may contribute to acne development. High-glycemic index foods, such as sugary snacks and processed carbohydrates, have been associated with increased acne severity. Dairy products and foods high in saturated fats may also worsen acne in some individuals.


Stress is known to trigger or worsen acne in some individuals. When you are under stress, the body releases stress hormones like cortisol, which can increase oil production and inflammation in the skin. Additionally, stress can disrupt sleep patterns and compromise the immune system, making it harder for the body to fight off acne-causing bacteria.


There is a genetic component to acne, meaning that if your parents or siblings have a history of acne, you may be more prone to developing it yourself. Certain genetic variations can affect how your skin produces oil, sheds dead skin cells, and responds to inflammation, making you more susceptible to acne breakouts.

Environmental factors

Environmental factors can also contribute to acne. Exposure to pollutants, such as cigarette smoke and air pollutants, can clog pores and irritate the skin, leading to acne. Additionally, using harsh or pore-clogging skincare products, not removing makeup properly, and wearing tight clothing or hats that trap sweat and oil on the skin can also contribute to acne development.

How to Prevent Acne

Cleanse your face regularly

One of the most important steps in preventing acne is to cleanse your face regularly. Use a gentle cleanser suited for your skin type to remove excess oil, dirt, and bacteria from the surface of your skin. Avoid scrubbing your face aggressively, as this can irritate the skin and worsen acne.

Avoid touching your face

Touching your face throughout the day can transfer bacteria, dirt, and oil from your hands to your face, clogging pores and leading to acne breakouts. Try to avoid touching your face unnecessarily and wash your hands regularly.

Choose suitable skincare products

Using skincare products that are suitable for your skin type is crucial in preventing acne. Look for non-comedogenic or oil-free products that won’t clog your pores. Avoid using heavy, greasy moisturizers or makeup that can contribute to acne breakouts.

Use non-comedogenic makeup

If you wear makeup, choose non-comedogenic or oil-free products that won’t clog your pores. Always make sure to remove your makeup before going to bed to allow your skin to breathe and prevent acne formation.

Keep your hair clean

Regularly washing your hair can help prevent oil and dirt from transferring onto your face and clogging your pores. If you have long hair, tie it back to keep it away from your face.

Avoid excessive sun exposure

While moderate sun exposure can have a temporary drying effect on acne, excessive sun exposure can worsen acne and lead to skin damage. Use sunscreen daily and seek shade during peak sun hours to protect your skin.

Maintain a healthy diet

A healthy diet can contribute to overall skin health and help prevent acne. Opt for a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit your intake of sugary, processed foods and dairy products, as they may worsen acne in some individuals.

Stay hydrated

Drinking an adequate amount of water each day can help maintain skin hydration and flush out toxins from your body. Aim for at least eight glasses of water per day to keep your skin healthy and hydrated.

Manage stress levels

Stress can worsen acne, so it’s important to find effective stress management techniques. Engage in activities that help you relax and unwind, such as practicing yoga, meditation, deep breathing exercises, or engaging in hobbies you enjoy.

Don’t pick or squeeze pimples

Although it can be tempting, picking or squeezing pimples can worsen inflammation and increase the risk of scarring. Instead, allow the pimples to heal naturally or seek professional advice for proper extraction techniques.

Medical Treatments for Acne

Topical treatments

Topical treatments are often the first line of defense against acne. These include over-the-counter products containing ingredients such as benzoyl peroxide, salicylic acid, or retinoids. They help to reduce oil production, exfoliate the skin, and kill acne-causing bacteria.

Oral medications

In more severe cases of acne, oral medications may be prescribed by a healthcare professional. Antibiotics, such as tetracycline or erythromycin, can help to reduce the number of acne-causing bacteria on the skin. Oral contraceptives may also be prescribed to women to regulate hormonal imbalances that contribute to acne.

Hormonal therapy

Hormonal therapy can be beneficial for individuals with hormonal acne. This type of treatment involves the use of medications that regulate hormone levels, such as oral contraceptives or anti-androgen medications.


Isotretinoin, also known as Accutane, is a powerful medication reserved for severe or treatment-resistant acne. It works by reducing sebum production, shrinking oil glands, and preventing the formation of new acne lesions. Isotretinoin has potentially serious side effects, so it must be prescribed and monitored by a healthcare professional.

Procedures and therapies

Certain procedures and therapies can be effective in treating acne and reducing its appearance. These include:

  • Chemical peels: Chemical peels involve applying a chemical solution to the skin to remove dead skin cells and unclog pores.
  • Microdermabrasion: Microdermabrasion uses a handheld device to exfoliate the skin and remove dead skin cells, oil, and debris.
  • Laser and light therapies: Laser and light therapies can target and destroy acne-causing bacteria, reduce inflammation, and promote healing.
