Acne: Basics to know and the treatment of acne 2025

What is acne vulgaris?

Table of Contents(toc)

Acne, also known as acne vulgaris is a common skin disease and disorder characterized by muliple lesions in skin. It affects mostly face area but may also affect neck chest and back in severe cases. 

Acne contains both inflammatory or noninflammatory lesions spread around that area. 

Acne mostly affects ‘pilosebaceous units’ you which is the name for ‘hair follicles’. 

Acne affects above mentioned area because these areas contain most of the oil glands. 

How does acne develop?

Acne is developed by following mechanism:

  • Clogging/blocking of opening in pilosebaceous unit
  • Excessive production of sebum (oil)
  • Infection of bacteria named: Cutibacterium acnes (Proprionibacterium acnes)
  • Subsequent formation of lesion or inflammation

Acne mostly affects the teenage and early adulthood population and most of the people get rid of acne by age of 25 or earlier. 

How is acne diagnosed?

After the lesions or acne is seen in the skin the physician carefully examines the skin. 

The common findings in  are:

  1. Open comedo (black head)
  2. Close comedo (whitehead)
  3. Papules
  4. Pustules
  5. Nodules
  6. Cyst formation
  7. Abscess formation
  8. Scarring in acne

Symptoms may also include discharge, pain and irritation of the lesions. 

As acne is more common in teenage to early adulthood and invilves face, acne maybe affecting the psychology of the person, independent of how severe the disease is. 

Diagnosis of acne by severity (severity classification)

Diagnosis of acne is mostly clinical. Following diagnosis maybe made by the physician depending up on the severity. 

  1. Comedonal acne
  2. Mild acne
  3. Moderate acne
  4. Severe acne/Nodulocystic acne

No lab tests are generally required for acne. In cSe of treatment failure and severe acne ghe doctor may decide to perform necessary investigations and tests. 

Comorbidities with acne:

Comorbidities like PCOS (POLYCYSTIC OVARIAN SYNDROME) and systemic disease like diabetes may need to be ruled out and the doctor may ask symptoms related to these disease and may even order necessary investigarions.

What other conditions can mimic acne?

There are few conditions similar to acne that doctor needs to rule out, includes acne conglobata, folliculitis, acneiform eruptions, etc. 

There a severe form of acne in which the infection of the bacteria causing acne spreads around whole body known as acne fulminans. It may need inpatient admission and treatment. 

Many other conditions like atopic dermatitis, other skin infections etc may coexis with acne which also should be carefully examined and accounted for cotreatment. 

Atopic dermatitis

Treatment of acne: 

Treatment of acne is simple in case of early treatment or less severe cases. 

What is the definitive treatment of acne? 

Now lets talk about treatment of acne. Treatment of acne depends upon severity of the acne. The severity of acne decides which of the available treatment can be directed to particular patient. The medications can be given single or in combination if severe acne is to be treated. 

The drugs that are commonly available and recommend for treatment of acne includes:

  1. Topical retinoids
  2. Topical antibiotics
  3. Systemic (oral ) retinoids
  4. Systemic/oral antibiotics
  5. Topical/systemic/oral steroids. 

Topical retinoids

They are first line of treatment. These medicines reduce number of comedones, open the pores and then control inflammation. This helps drainage of sebum as well as reduction in bacterial load. 

This also helps with prevention of scarring and reative hyperpigmentation as well. 

Commonly used topical retinoids include adapalene, tazarotene, and tretinoin. 

  • adapalene
  • tazarotene
  • tretinoin. 

These medicines are applied on e daily in well washed dry skin. Side effects of retinoids include skin peeling, irritation, and redness. This should resolve by a week or two. The person using these drugs should be gentle with their skin and can ise non comedogenic moisturizer for prevention of dryness and irritation. 

  • As they make the skin thin one should well protect their skin from sun and stay protected by application of sunscreen or staying inside. 
  • Other measures like protective covering while going outside also help.
  • If the side effects like irritation and peelings is persistent, alternative day dosing can be done.
  • Amount should be minimal with vey thin layer formation in skin and should not be applied to eyes. 

Topical antibiotics:

Topical antibiotics commonly used for acne vulgaris include: clindamycin, erythromycin, minocycline,benzoyl peroxide and dapsone.

  • clindamycin
  • Erythromycin
  • minocycline
  • benzoyl peroxide
  • dapsone

These drugs have antibacterial as well as anti-inflammatory effect on skin.

This antibiotics should  never be used alone but are used in combination with topical retinoids. This is done to prevent the antimicrobial resistance.

Other topical medicine include antiandrogen drug like clascoterone. It is a topical androgen receptor inhibitor and hence it reduces action of androgen in skin.

Systemic antibiotics:

Oral antibiotics commonly prescribed for acne include Doxycycline, minocycline, tetracycline, sarecycline.  Previously erythromycin also used to be prescribed but it is less prescribed now due to resistance. Occasionally oral clindamycin, azithromycin and sulfamethoxazole is also used. 

Hormonal therapy:

Antiandrogen agents like spironolactone can be useful for controlling acne. Similarly, estrogen helps in reducing production of sebum helping with treatment of acne. 

Oral isotetrinoin:

It is a systemic retinoid which is highly effective in treatment of moderate to severe acne vulgaris. It has anti inflammatory, and antibiotic role . 

For dose of isotetrinoin refer here.

Warning: Isotetrinoin is teratogenic. It may cause birth defects. Hence, pregnancy should be strictly avoided during isotetrinoin treatment. 

Following investigation are mandatory before starting isotetrinoin then repeated monthly.

Note: Pateints may have abnormal health and wound physiology upto one year from isotetrinoin discontinuation. Some patients may be prescribed with steroids while starting isotetrinoin . 

Surgical management of acne:

Some cases like large inflammatory, cystic and nodular acne may get benefits from injection of steroids in acne site. (intralesional steroids). Some benefits maybe from laser and lught therapy. While surgical extraction, and incision and drainage may also be useful.

Some medications not mentioned above include: Azelaic acid, tazarotene, trifarotene, daptomycin, glycolic acid and salicyalic acid.

Superficial peels that use glycolic or salicylic acid can be used for some cases for treatment of acne. 

What are the treatment of acne in Nepal?

Multiple medications, which includes all of the above are available in Nepa for treatment of acne. 
Acnecare  and some other medicines are common. These drugs are commonly called acne face creams and are available in cosmetic shops over the counter OTC. Many such cosmetic products are sold under names acne soap for face, acne face wash, adapelene gel, clean and clear face wash etc. There are best dermatologists in nepal which can easily handle your condition and get you rid of acne and ppimples to give you gowing white skin.

What is USMLE?

The United States Medical Licensing Examination (USMLE) is a famous three-step standardized examination that medical students and graduate doctors must pass in order to obtain a clinical practice license to practice medicine in the United States of America.

The exam is designed to assess and evaluate a physician’s ability to apply clinical knowledge, health concepts, and principles that are important for the effective patient care and the practice of medicine in healthcare settings.

Here’s a brief overview of the three steps:

  1. USMLE Step 1:

    • This step focuses on the basic sciences that form the foundation of medical practice, including anatomy, biochemistry, physiology, pharmacology, microbiology, pathology, and behavioral sciences.
    • It is typically taken after the second year of medical school.

  2. USMLE Step 2:

    • Divided into two parts:
      • Step 2 CK (Clinical Knowledge): Tests clinical knowledge through multiple-choice questions covering internal medicine, surgery, pediatrics, psychiatry, obstetrics and gynecology, and other specialties.
      • Step 2 CS (Clinical Skills): This component was previously used to assess clinical skills through patient interactions, but it has been permanently discontinued as of January 2021.
    • Step 2 CK is usually taken during the fourth year of medical school.

  3. USMLE Step 3:

    • Focuses on clinical management and the ability to apply medical knowledge in patient care scenarios.
    • It is usually taken during or after the first year of residency.

Passing all three steps of the USMLE is a requirement for obtaining a medical license in the U.S. and is often necessary for international medical graduates (IMGs) who wish to practice in the country.

TINEA FACIEI: Bad-looking itch on your face Diagnosis!

What is tinea faciei?

It is infection of face with a dermatophyte fungus. It does not include infection of beard and moustache area, which is called tinea barbae. Tinea faciei is uncommon and often misdiagnosed at first.

What causes tinea faciei?

Tinea faciei can be due to an anthropophilic (human) fungus such as Trichophyton rubrum (T rubrum). Infection often comes from the feet (tinea pedis) or nails (tinea unguium) originally. Zoophilic (animal) fungi such as Microsporum canis (M canis) is acquired from cats and dogs, and T verrucosum, from farm cattle, are also common.

How is tinea faciei diagnosed?

Tinea faciei resembles tinea corporis (ringworm). It may be acute (sudden onset and rapid spread) or chronic (slow extension of a mild, barely inflamed, rash). There are round or oval red scaly patches, often less red and scaly in the middle or healed in the middle. Lesions are usually asymmetric and it is often unilateral. It is frequently aggravated by sun exposure. It may presenta as kerion (fungal abscess).

What should we care if we have tinea faciei?

It is essential to look for and treat tinea infection elsewhere (look at the feet, groins, and nails) and in a suspected zoophilic infection, identify, isolate and treat the source animal.

Look at these dermatology question for your upcoming exams. 

Tinea faciei pathophysiology?

-Tinea faciei is the name used for infection of face with a dermatophyte fungus(T.rubrum)

Clinicalℹ️:round and oval red 🔴(less scaly in middle) scaly patches Acute(Sudden onset and rapid spread),Triggered by sun ☀️

What is treatment of Tinae faciei?

✅Terbina,itraconzole, fluconazole

Here is dose and route written for treatment of Tinea faciei:

  1. Cap Itraconazole 100 mg PO BD 4 weeks OR
  2. Tab Itraconazole 250 mg PO OD 6 weeks (upto 12 weeks for onychomycosis) OR
  3. Cap fluconazole 150 mg once weekly upto 6 weeks
  4. Oint clotrimazole or terbinafine or  Ketoconazole luliconazole or miconazole nystatin or topically one to three times a day

Varicella zoster


Definition of Postherpetic neuralgia (PHN)

Postherpetic neuralgia (PHN) is a localized dermatomal neuropathic pain experienced 1 month after herpes zoster.

Immunosuppression is the commonest risk factor for PHN.

Varicella-zoster virus (VZV) is the causative agent of varicella, or ” the chickenpox,” and herpes zoster, or “shingles.”

Acute herpes zoster typically presents with a rash that is painful but self-limited. Some patients may continue to experience pain for months to years after the resolution of the rash, a condition known as postherpetic neuralgia (PHN).

Risk factors for post herpetic neuralgia

  1. age more than 60 years
  2. severe pain during acute herpes zoster
  3. severe or more rash with acute herpes zoster

How long does the pain of PHN lasts?

Generally pain of PHN lasts from few months to several. Most of them last for few months.
Is there sensory loss  with PHN?
Yes, the same dermatomes involved with herpes and PHN may also have sensory loss like loss of thermal, tactile, inprick or vibration sensations.
Occasionally the sensory deficit may cross dermatome margins but the uninvolved contralateral dermatomes are normal or unimpaired.
herpes zoster

Does PHN cause allodynia?

Allodynia is a condition that causes pain from the stimuli that normally wouldnt cause pain suchas light touch, brushing, combing hair, wearing clothing etc.
And PHN may occasionally cause allodynia as well.

Pain in Postherpetic neuralgia (PHN)

Broadly type of pain in PHN is divided into two broad categories spontaneous and stimulus evoked.

Spontaneous pain can be either continuous (burning, aching, throbbing) or intermittent (stabbing, shooting, electric-shock-like pain). Stimulus-evoked pain can present as allodynia and hyperalgesia. Allodynia is the commonest type of pain reported in PHN.

Diagnosis of PHN

The diagnosis of PHN is made when localized neuropathic pain persists beyond three months in the same distribution as a preceding documented episode of acute herpes zoster.
Testing for varicella-zoster virus (VZV) antibodies in the blood or cerebrospinal fluid is available and may be useful in atypical cases to confirm past exposure to the virus; however, positive tests do not specify PHN as the source of pain
Differential diagnosis of PHN
  1. Trigeminal neuropathy
  2. Other forms of craniofacial pain
  3. Acute radiculopathy
  4. Diabetic amyotrophy and idiopathic lumbosacral radiculoplexus neuropathy
  5. Recurrent acute herpes zoster

Treatment of  Postherpetic neuralgia (PHN) with local anesthetics

Local anesthetics act by suppressing sodium channels and decreasing ectopic discharges, thus reducing membrane excitability.

Lignocaine has faster onset of action (2-3 min) of but the duration of action (2 h) in contrast bupivacaine though is slow to act but has a continued activity for longer time (4-8 h).

There is no consensus on the concentration of anesthetics required, though few studies have reported a dose-related effect.

Treatment of Postherpetic neuralgia (PHN)

Intradermal therapy leads to faster onset of action, and the reservoir effect leads to sustained action with less systemic absorption. A higher dose of local anesthetics may cause arrythmias

Steroids and Anesthetics for Postherpetic neuralgia (PHN)

A combination of dexamethasone and local anesthetics gives a good response in stimulus-induced postherpetic neuralgia

Treatment options for PHN

Following medications can be used for treatment of PHN:
  1. Gabapentinoids like gabapentin or pregabalin
  2. Tricyclic antidepressants TCAs like Amitriptyline, Nortriptyline, Desipramine
  3. Capsaicin topical
  4. Lidocaine patches
  5. Antiseizure medications like valproic acid, carbamazepine, oxcarbazepine. lamotrigine
  6. SNRI like duloxetine, venlafaxine
  7. Botulinum toxin
  8. Opioids
  9. Glucocorticoid injections
  10. Neuromodulation and nerve stimulation like TENS, Pulse radiofrequency, spinal cord stimulation
  11. Cognitive behavior therapy

Jaipur block for Postherpetic neuralgia (PHN)

Jaipur Block is a cocktail injection of ( Dexamethasone+ Lignocaine + Bupivacaine ) given to a patient of PHN.

Prevention of PHN

Prevention of PHN involves either treatment of acute zoster or the use of a vaccine to decrease the incidence of acute zoster and PHN.
