Read on to learn and understand the different types of acne, its causes and treatments. 

What is Acne? 

Acne is a common skin condition characterised by pimples, bumps or blemishes, mainly on the face. It is a condition that can profoundly affect one’s self-image and confidence. 

People facing acne problems day and night strive to get rid of it. If you suffer from acne, you know that acne can be quite confusing and complicated. You can never be sure when a single pimple may show up or when your entire face can break out. Sometimes your routine cream helps, and sometimes it doesn’t. All of this is because there are multiple reasons for acne and different factors working with one another to trigger acne. Genetics, hormones, diet, lifestyle, environment, cosmetics etc., are just a few examples.

Today let us dive in and explore types of acne and how dermatologists assess acne before managing it. 

Doctors usually divide acne as non-inflammatory and inflammatory:

What is acne?

Non-Inflammatory Acne

Non-inflammatory acne is one of the most common types of acne that doesn’t involve inflammation or redness. It is the first step in the acne formation process. The mildest form of acne. Here the hair follicles and the skin pores are all clogged up because of oil, dead skin cells and dirt, causing the oil glands to swell up and come up on the skin as bumps –

  • Comedones

Comedones are the first to form when you get acne. It has a bumpy structure and makes the skin uneven. Comedones can thus be felt more than seen. You can feel them like small beads or bumps underneath your skin. Comedonal acne is broadly known as whiteheads and blackheads, also called open comedones and closed comedones. 

  • Open Comedones

The blackheads are known as open comedones. In this type of acne, skin pores open, and the oil block reacts with the air becoming black. Some people think it’s dirt, but it’s open comedones. Having blackheads is a sign that your skin is producing extra oil and is acne-prone. 

  • Closed Comedones

The whiteheads are known as closed comedones. Here, the skin pore openings are closed, and the oil block cannot come out, raising a small bump. Similarly, like blackheads, having a lot of whiteheads is a sign of impending breakouts. 

Inflammatory Acne

Inflammatory Acne

When the bacteria invade a blocked oil gland and start growing, our immune system tries to fight the bacteria. This causes inflammation – which is seen as redness, pus points and painful deep bumps. Inflammation tells us that the acne process has gone deep and become severe and usually requires proper treatment. 

Let us look into the different types of acne.

  • Papules and Pustules 

Acne papules are a form of lesion on the skin. Papules are caused by a buildup of oil and germs inside the pore that is limited by dead skin cells. It closes the pores and enlarges and infects the hair follicle. It then transforms into a massive red lump filled with pus and a fluid mixture containing inflammatory cells. 

Pustules are when the pus inside the hair follicle comes up and is seen as a plus point. Papules and Pustules are the most common type of acne observed, and they are also known as zits or pimples.

  • Nodules

Nodules form when the above-mentioned oil mixture, bacteria and cells go deeper and spread beyond the oil gland and hair follicle. Just like comedones, nodules are felt more than seen. On touching, these pimples think like a small hard bead or seed inside the skin. Many times they are very painful to touch. 

  • Cysts

Cysts are the most severe type of pimples. They form when deep nodules grow bigger and finally burst inside the skin, creating a small area full of oil, cells and pus. It is as if a small bubble is formed inside the skin. 

Nodules and cysts are severe forms of acne and are frequently associated with many redness, acne spots and scars. 

Types of Acne

Different Types of Acne Based on the Site

Moving on, we all know that we can get acne not only on the face but on other parts of the body as well. Accordingly, these pimples can be classified based on their location:

  • Face Acne or Acne Vulgaris

Acne (pimples) Vulgaris (common) – commonly seen pimples. 

The face is the most common site to get pimples; thus, facial acne, also known as acne vulgaris, is the most common acne seen.

Starting at puberty, troubling throughout teenage and finally settling after the 30s is the usual journey that faces acne goes through.  

  • Back Acne or Truncal Acne

When acne vulgaris becomes severe and spreads to the chest, back, or shoulders, the condition is known as truncal acne or back acne. Acne on the trunk can often result in scarring and pigmentary issues. As a result, it is vital to detect the condition early to begin treatment on time.

  • Forehead Acne

When the pores on your forehead become clogged with dead skin cells, oils, and germs, they start forming pimples on the forehead. Using a lot of oil in the hair, oily hair care products, dandruff, using a bandana or forehead bands etc., are a few of the common reasons for acne

  • Scalp Acne

Scalp acne

Acne and outbreaks on the scalp are known as scalp acne. The main reason for acne can be the excess of oil. Also, acne on the scalp is less prevalent than in other areas, yet it can be troublesome. If you are suffering from scalp acne, the doctor’s prescribed shampoo or scalp treatment can help you. 

  • Acneiform Eruptions

Acneiform eruptions are a collection of skin conditions marked by papules and pustules that look like acne but are not acne per-se. Acneiform eruptions are caused due to some external factor or application like medicated creams, oils, grease, tight clothes etc, that block the skin pores, causing acne. They can occur almost anywhere on the body, including the face, arms, buttocks, thighs etc.

Most of the time, acneiform eruptions are treated by simply removing the cause of acne and letting the skin breathe. 

Special Types of Acne

These special acne variants are commonly seen nowadays and can be quite troublesome if not treated properly. 

  • Acne Cosmetica

Acne caused by cosmetics is termed acne cosmetica. This types of acne are a mild but tenacious form of acne and can appear anywhere on the body, but the face, neck, hairline, and scalp are the most commonly affected areas. Acne cosmetica appears as tiny bumps on the skin’s surface or the scalp. 

They are commonly caused due to frequent changes in cosmetics and the use of multiple cosmetics, which in turn irritate the skin, giving acne. 

Acne Cosmetica

  • Maskne – Mask Acne 

Acne caused by wearing a face mask is known as Maskne. We have seen a rise in this type of acne with the pandemic of COVID-19. In combination with friction, the humid and obstructive environment inside the mask can retain moisture from breathing, talking, or sweating, leading to the maskne.

Although maskne is inconvenient, it is critical to continue using facial coverings throughout  COVID-19. One can avoid maskne by practising good mask-wearing behaviours such as not re-wearing the same mask for too long and using clean cotton masks where possible.

  • Oil Acne

An excess of oil on the skin or exposure to heavy oils causes acne, which is known as oil acne. Using facial and body oil or hair oil seeping on the face are a few of the common reasons for acne.  Methods like oil cleansing and double-cleansing can help get rid of oil acne. 

  • Drug-induced Acne

Drug-induced acne is a skin disorder with symptoms similar but not identical to common acne. Various medications can cause drug-induced acne Drugs like corticosteroids, lithium, vitamin B12, thyroid hormones, halogen compounds, antibiotics, and anti-tuberculosis medicines can cause acne as a side effect. Contact your doctor or dermatologist for acne treatment in Pune if you experience a breakout after taking any of these medications. It is not recommended to stop these medicines on your own.

Grades of Acne

Any acne treatment is considered after noting the grade of acne. Acne has four different grades based on its appearance and severity. Though the severity of the disease differs from person to person, knowing the grade will make determining the best acne therapy easy. The severity of acne determines the treatment. The severity of acne in the same person might vary depending on hormonal changes, stress levels, and other factors. As a result, doctors need to modify acne treatments to produce the best outcomes. Here is the acne ranking based on severity by dermatologists:- 

  • Grade 1 Only Comedones 

The mildest type of acne is seen at the initial stages. Early treatment and good skin care at this stage prevent severe breakouts.

  •  Grade 2 Comedones and Few Papules 

Usually, inflammation begins at grade 2. Proper treatment at this stage prevents the formation of spots and scars.

  •  Grade 3 Deep Papules and Nodules

This is the stage where severe acne starts. Grade 3 requires good guidance and treatment from a dermatologist to prevent skin damage.

  •  Grade 4 Severe Nodules, Cysts, and Scarring Acne

It is the most severe form of acne and requires aggressive acne treatment in Pune from a qualified dermatologist.

Acne Treatment

Acne comes in a variety of forms, grades, and treatments. The severity of the condition determines acne treatment in Pune. Some people can treat themselves with home cures, while others need to see their dermatologists. Let’s have a look at the different treatments for various types of acne.

Acne Treatment

Furthermore, a good skincare routine can assist acne-prone skin maintenance and aid treatment. Mild comedones can be treated with skincare. Your doctor can help you choose your skincare products according to your skin type and acne. 

  • OTC Products

OTC or over-the-counter products are creams, lotions, cleansers etc., that can be bought without any prescription. They contain lower concentrations of active medicines and can be used as a step up from routine skincare to reduce your acne. 

Benzoyl peroxide, Salicylic acid, Alpha hydroxy acids, and Sulphur are some common chemicals available in OTC acne products.

Though a good option for mild to moderate acne, they can have limited results after a certain time. 

  • Topical Medicines

Topical medicines are the medicines that your doctor gives you to apply to the skin directly. These medicines act locally on acne and skin – fighting bacteria and inflammation. 

Antibiotics like clindamycin, Retinoids ( tretinoin), Benzoyl peroxide, and Salicylic acid  Alpha Glycolic Acids (Glycolic Acid) are a few of the most common topical medicines used in the treatment of acne. 

These are medical-grade products and need to be prescribed by a certified dermatologist.
