Closed Comedones vs Fungal Acne: What’s the difference?

Technically, fungal acne is not acne so here we will learn about closed comedones vs. fungal acne. That is a result of a very distinct cause.

Bacteria are to blame for clinical acne. A bacterial overgrowth that soon develops into acne and pimples can be brought on by clogged pores brought on by pollution, dead skin cells, sebum, and heavy skin care products.

Conversely, yeast overgrowth causes fungus to cause acne (Malassezia). Your skin naturally contains yeast. You may develop acne, though, if the hair follicles become overgrown.

What is fungus-induced acne resemble? Little red pimples can appear on your chest, upper back, forehead, cheeks, or fungus acne.

Brief Overview of Fungal Acne

Fungal acne, also known as Malassezia folliculitis or Pityrosporum folliculitis, is a skin condition caused by the overgrowth of yeast (Malassezia) in the hair follicles. It often presents as small, itchy, uniform pustules or papules and can be mistaken for traditional acne. This condition thrives in warm, humid environments and is common in areas with excessive sweating and oil production.

 Different Types of Fungal Acne

  • Pityrosporum Folliculitis

Characterized by itchy, acne-like eruptions, often in areas with high oil production.

  • Malassezia Folliculitis

Similar to Pityrosporum folliculitis, caused by Malassezia yeast, leading to itchy, uniform pustules.

 Brief Overview of Closed Comedones

Closed comedones, commonly known as whiteheads, are a type of non-inflammatory acne that presents as small, flesh-colored bumps. These bumps occur when dead skin cells, oil, and bacteria become trapped within the hair follicles. Unlike blackheads, which have an open surface, closed comedones have a closed surface, which prevents the contents from being exposed to air.

What are Closed Comedones and Comedonal Acne?

A specific type of acne is one with comedones. Comedonal acne is less severe because it doesn’t result in cysts and nodules like inflammatory acne does.

Open comedones (blackheads) and closed comedones are the two types of comedonal acne (whiteheads).

Contrary to popular belief, dirt doesn’t turn blackheads black. The blackness you observe results from the dirt obstructing your pores and oxidizing since the acne is open.

Also, whiteheads aren’t necessarily white. Closed comedones and fungus acne can both frequently appear as red pimples, making them quite similar.

 Different Types of Closed Comedones

  • Microcomedones

Early-stage comedones are tiny and not visible to the naked eye.

  • Macrocomedones

Larger, visible closed comedones that appear as small, flesh-colored bumps on the skin.

  • Fungal acne affects boys and men more than it does women.

Blockage of hair follicles by dead skin cells and sebum. Closed comedones (whiteheads) are non-inflamed skin lesions that develop when oil and skin debris clog skin pores. To help remove the clog and enhance your appearance, they can be treated with over-the-counter or prescription lotions and physical extraction.

Hormonal changes, genetic predisposition           

Contributing Factors

Hormonal imbalances (e.g., during puberty or menstruation)

Where Does Fungal Acne Appear?

  • Forehead: Frequently affected due to high oil production and sweat accumulation.

  • Cheeks: Can appear in areas with oily skin and where hair follicles are abundant.

  • Face: Often seen in the T-zone where the skin tends to be oilier.

Closed Comedones vs Fungal Acne: what are the differences?

Closed comedones vs. fungus acne have extremely similar appearances. They appear as tiny red pimples on your forehead, upper back, or cheeks. But they are in no way comparable. One is that many factors bring them on.

Yeast overgrowth is the cause of fungal acne. In contrast, closed comedones develop due to an overproduction of sebum in a layer of skin.

Closed comedones vs. fungal acne require completely different approaches to therapy.

How to Treat Fungal Acne and Closed Comedones

Your therapy method can only be successful if you mistake fungal acne for closed comedones. Because of this, it’s crucial to determine the type of acne you have before beginning any treatment.

Topical retinoids and drying agents are effective treatments for comedonal acne. Also, reducing the excessive oil production in your skin can successfully treat comedones.

You might require a prescription for systemic antibiotics if you have closed comedones and inflammatory acne. As an alternative, hormonal medications (such as contraceptives) can potentially aid in treating severe acne.

But antibiotics won’t help you much if you have fungal acne. You will require anti-fungal medicine instead. Try a topical antifungal cream first, but you could need more if your condition is serious.

Also, under the guidance of a board-certified dermatologist, you might need to attempt oral antifungal medication if your skin doesn’t respond to topical therapy.

Remember not to pop pimples no matter what form of acne you have. Open lesions are more problematic than acne since they are so easily contaminated.

When an open zit heals, it may leave a scar or melanin spots, which cause the surrounding skin tone to shift. Because of this, it is preferable to put your faith in a treatment alternative.

Fungal Acne Treatment

Spending time in damp or humid environments increases the risk of developing fungal acne. The breeding habitat for bacterial acne is warm, damp skin. You should take certain precautions to reduce your chance of developing fungal acne if you exercise frequently, participate in sports, or reside in an area with excessive heat and humidity all year.

Try to shorten the period you perspire heavily. Shorter sessions or other kinds of exercise may result from this. Keep your skin from chafing during exercises by using comfortable, loose-fitting clothing made of breathable material, such as cotton.

After working out, take a shower and put on dry clothing as soon as you can. Taking a chilly or cold shower after exercising can help you stop sweating. You should visit your doctor for prescription antifungal medications or topical antifungal treatments for fungal acne because fungus-related acne is essentially a yeast infection. Make sure to apply any creams or ointments in the direction that your hair naturally grows.

Avoid rubbing the lumps while waiting for your fungus acne to disappear. This makes it more difficult to cure the infection and can spread it.

Closed comedones treatment

Treatment for comedones acne can be quite difficult. This kind of breakout is frustrating since treatment methods can take many weeks to a few months to start working.

Changing to a healthier lifestyle is the first step. Limit your intake of sweets, dairy products, and harmful fats. If you smoke, give it up. Make careful to cleanse your face at most twice each day.

Next, try a topical medication available without a prescription that has one of these active ingredients:

  • Salicylic acid
  • Glycolic acid
  • Azelaic acid
  • Benzoyl peroxide
  • Retinoids
  • Also, opt for oil-free, non-comedogenic moisturizers, and cosmetics.

If over-the-counter remedies are ineffective, a prescription-strength drug can help. They could consist of hormone therapy, prescription-strength retinoids, or antibiotics. Dermatologists can also do electrosurgery, cryotherapy, or microdermabrasion, which involves freezing the skin’s surface to eliminate comedones.

Red and blue light treatment is a relatively modern but professionally tested way of treating acne. Red light reduces inflammation and promotes healing, while blue light eliminates acne-causing germs on the skin.

 Conclusion

Acne caused by fungi and comedones is not the same thing. In the clinical sense, fungal acne is not acne, as we have already discussed.

Malassezia, also known as Pityrosporum folliculitis, is a fungus that affects the hair follicles, where comedonal acne is brought on by a concoction of bacteria, oil, and clogged pores.

Because of this, the methods of treating through typical acne medication or other method, these two skin disorders are highly dissimilar. Determining which illness you have might be challenging, but speaking with a doctor or dermatologist can help you receive the right diagnosis and the best possible care.
