What’s Pityrosporum Folliculitis?

 

 

What exactly is Pityrosporum folliculitis?  Pityrosporum folliculitis is also known as Malassezia folliculitis.  Malassezia is a yeast commonly found on skin and is generally harmless.  Generally.  The problem occurs when the environment is ripe causing these yeast to overgrow and invade hair follicles thus causing a fungal infection of the skin.  Often times the result is an acne-like eruption.  In fact, this condition looks so much like acne it’s often misdiagnosed as such!

The key difference between Malassezia or Pityrosporum folliculitis and acne is the itch that some say they experience with this condition.  Itchiness, as you might know, is a common symptom of fungal infections.

 

One other notable difference between Pityrosporum folliculitis and acne is the lack of response to acne treatment.  Frankly, acne medications won’t work on Pityrosporum folliculitis for the same reason why they won’t work on Athlete’s Foot.  Two entirely different skin conditions.

 

Aside from acne products being completely ineffective against this skin condition, here’s another reason why you may want to avoid using them.  Many acne medications work by killing bacteria but this only allows for yeasts like Malassezia to flourish. In the absence of bacteria, yeasts have the ability to consume all of the resources and nutrients they would’ve normally had to compete for.  Kill the bacteria and you aren’t just helping yeast live; you’re helping them thrive.

 

Now, here’s where things get a little tricky: acne can still be present along with Pityrosporum folliculitis.  Yes, you read that correctly.  This means you could have acne and an overgrowth of this yeast at the same time.  How?  Well, oily skin is a risk factor for both of these conditions.  The same oil that clogs your pores and causes acne is the same oil this yeast feeds off of.

 

If you think you’re experiencing acne and Pityrosporum folliculitis, try to tackle one condition at a time to avoid complicating matters.  In case you’re wondering which should you try to resolve first, the answer is folliculitis.  Since we know acne treatments may worsen Pityrosporum folliculitis, it’s best to use them only after you have successfully treated the folliculitis.

 

Still, just like other fungal infections of the skin, there’s a possibility of recurrence;  so, even after successful treatment, Pityrosporum folliculitis can come back.  Again, think Athlete’s Foot.  Just because you got rid of it once doesn’t mean it can’t come back again.  Therefore, it’s important to know what the risk factors are and how to prevent it in the first place.

Finally, Pityrosporum folliculitis can occur wherever hair follicles are located, but typically appears on the face, back, neck, chest, and shoulders.  It can affect young to middle-aged people, males and females and, unfortunately, is a lot more common than we might think.

 

Nevertheless, this condition is usually only discovered after months and sometimes years of unsuccessfully trying to resolve what is thought to be acne.

 

If you suspect you have Pityrosporum folliculitis, it’s always a good idea to get confirmation from a licensed dermatologist.  If you suspect you might have both acne and Pityrosporum folliculitis, well, a licensed dermatologist can help with confirming that, too.

 

And, here’s the good news: just like acne, depending on the severity, you may be able to treat this condition effectively at home.  Click here to read what might help.
