Hormonal Acne vs. Fungal Acne: How to Tell the Difference
If your breakouts are not responding to acne treatments, you may not be dealing with acne at all. Fungal acne looks similar but is caused by yeast, not clogged pores, and it needs the opposite approach.
Here is how to tell hormonal acne and fungal acne apart, so you stop treating the wrong condition. This is general education, not a diagnosis, a dermatologist can confirm which you have.
What each one actually is
Hormonal acne is true acne: hormones increase oil, which mixes with dead skin and bacteria to clog pores, producing whiteheads, deeper cysts, and inflamed spots, often on the lower face and jaw, on a monthly rhythm.
Fungal acne (technically Malassezia folliculitis) is an overgrowth of yeast in the hair follicles. It is not really acne at all, which is why acne treatments do not fix it and can sometimes make it worse.
How to tell them apart
A few signs usually distinguish them.
Appearance
Fungal acne is uniform, small, same-size itchy bumps in clusters. Hormonal acne varies, mixing whiteheads, blackheads, and deeper cysts.
Itch
Fungal acne often itches. Hormonal acne usually does not.
Location
Fungal acne favours the chest, back, shoulders, and hairline. Hormonal acne favours the jaw, chin, and lower face.
Timing
Hormonal acne flares with your cycle. Fungal acne flares with heat, sweat, and humidity, not your period.

PhaseBloom maps hormonal breakouts that follow your cycle to where you are in your cycle and builds an AM and PM routine that changes as your hormones do, so you treat breakouts before they start.
Why the treatments differ
This is the crucial part: they need opposite care. Fungal acne responds to anti-fungal treatments and is often fed by the oils and rich moisturisers that some acne routines rely on. Standard acne actives and antibiotics do not target yeast.
Hormonal acne responds to oil-clearing actives, pore care, and, importantly, working with the hormonal rhythm that drives it. Treating fungal acne like hormonal acne (or vice versa) is why so many people feel stuck.
What to do next
If your breakouts itch, are uniform in size, sit on your chest and back, and ignore your cycle, fungal acne is worth investigating with a dermatologist. If they vary in type, cluster on your jaw and chin, and flare before your period, hormonal acne is the more likely driver.
Tracking when and where your breakouts appear, and whether they track your cycle, gives you and a professional the clearest picture of what you are actually treating.

Frequently asked questions
How do I know if my acne is fungal or hormonal?
Fungal acne is uniform, small, itchy bumps clustered on the chest, back, and hairline that flare with heat and sweat. Hormonal acne varies in type, favours the jaw and chin, usually does not itch, and flares with your cycle.
Why won't my acne treatments work?
If standard acne treatments are not helping, you may have fungal acne, which is caused by yeast, not clogged pores. It needs anti-fungal care, and acne actives can sometimes make it worse.
Does fungal acne come with your period?
No. Fungal acne flares with heat, sweat, and humidity rather than your cycle. Breakouts that reliably worsen before your period point to hormonal acne instead.
Can you have both fungal and hormonal acne?
Yes, it is possible to have both at once, which makes them harder to untangle. Tracking the timing and location of your breakouts and seeing a dermatologist gives the clearest answer.
