If your skin gets worse every June and July - more bumps, more congestion, everything feeling sluggish - you're probably not dealing with regular acne. In India's humid monsoon season, two very specific concerns tend to flare up at the same time: fungal acne and closed comedones.
They look almost identical, but they have completely different causes and need completely different fixes. Using the wrong approach doesn't just fail to work - it can make things worse.
What is fungal acne, and why does monsoon trigger it?
Fungal acne isn't technically acne at all. The clinical name is Malassezia folliculitis. It's caused by an overgrowth of Malassezia, a yeast that lives naturally on everyone's skin. Normally it doesn't cause problems. In high humidity and heat - exactly what monsoon delivers - it grows faster than the skin can manage, gets into hair follicles, and causes inflammation.
The result is clusters of small, uniform bumps. They tend to show up on the forehead, along the hairline, across the cheeks, and on the chest or back. They're often itchy, which is one of the key differences from regular acne. They look like pimples but they don't come to a head the way a regular pustule does.
Monsoon accelerates this because sweat, humidity, and warmth create exactly the environment Malassezia thrives in. Products with certain fatty acids - many moisturisers, hair oils, and even some sunscreens - can also feed the yeast, making flares worse without you realising why.
What are closed comedones?
Closed comedones are clogged pores where the opening stays sealed. Sebum and dead skin cells build up beneath the surface, forming a bump with no visible head. They're not infected or inflamed the way a pustule is, but they can become one if bacteria get involved.
They commonly appear on the forehead, chin, and nose area. In monsoon, excess sebum production combined with heavier skincare products - anything too occlusive for the humidity - increases the likelihood of pores getting blocked.
Unlike fungal acne, closed comedones are a mechanical problem: too much oil, too much dead skin, not enough exfoliation, products that are too rich for the season. They don't itch. They don't cluster uniformly. Each one is slightly different.
How to tell them apart
| Feature | Fungal acne | Closed comedones |
|---|---|---|
| Appearance | Small, uniform, clustered | Varying size, scattered |
| Itchiness | Common | Rare |
| Location | Forehead, hairline, chest, back | Any zone, often T-zone |
| Trigger | Heat, humidity, certain ingredients | Clogged pores, heavy products, excess oil |
| Worsens with | Fatty acid-rich products | Heavy occlusive moisturisers |
| Treatment | Antifungal ingredients | BHA, gentle exfoliation |
The easiest self-check: Are the bumps itchy? Are they all roughly the same size and grouped together? If yes, lean toward fungal acne. If they're scattered, different sizes, and not particularly itchy, you're more likely looking at closed comedones. Both can occur at the same time, especially in monsoon.
What triggers fungal acne (ingredients to watch)
This is where a lot of people get stuck. Fungal acne can persist for months even with a solid routine because certain ingredients in otherwise good products actively feed Malassezia. Fatty acids with chain lengths between C11 and C24 are the main culprits.
Ingredients that can trigger or worsen fungal acne:
- Coconut oil, olive oil, flaxseed oil, soybean oil
- Oleic acid-heavy oils in general
- Fatty alcohols like cetyl alcohol and stearyl alcohol in higher concentrations
- Some fermented ingredients (depending on formulation)
Ingredients that are generally safe for fungal acne:
- Caprylic/capric triglyceride (short-chain, doesn't feed Malassezia)
- Mineral oil and petrolatum
- Squalane (from sugarcane, not olive)
- Niacinamide, hyaluronic acid, glycerin
If your skin is going through a fungal acne flare, it's worth looking at every product label - including your hair oils. Oil running down your forehead during monsoon can be a surprisingly consistent trigger.
How does niacinamide help closed comedones?
Niacinamide is one of the most useful ingredients for preventing closed comedones. It regulates sebum production by signalling the sebaceous glands to slow down oil output. Over time, this reduces the volume of material that can block pores. It's also anti-inflammatory, which means it supports the skin while you address the comedones.
A niacinamide serum used consistently - once daily is enough - addresses the oil regulation side of closed comedones without disrupting the skin barrier. This matters in monsoon because aggressive exfoliation on a compromised barrier can cause more problems than it solves.

What actually fixes closed comedones
Closed comedones respond to exfoliation, specifically to chemical exfoliants that dissolve the buildup inside the pore rather than scrubbing the surface.
Salicylic acid (BHA) is oil-soluble, which means it gets inside the pore lining and breaks down the debris from the inside out. At 2%, used 2-3 times per week, it's effective for most people. Daily use can over-exfoliate and weaken the barrier - the exact opposite of what you want during a humid season when the barrier is already under stress.
AHAs like glycolic acid work on the skin's surface, removing dead skin cells that contribute to pore congestion. They're better for tan removal and overall texture than deep pore work, but they support BHA well as part of a regular routine.
Retinol increases cell turnover and prevents the buildup that leads to comedones, but it takes 8-12 weeks to show results and can cause purging and initial dryness - not ideal as a starting point in monsoon if your barrier is already stressed.
The simplest starting point: a 2% salicylic acid product, 2-3 times a week, with a lightweight, non-comedogenic moisturiser after. Let the barrier stabilise before adding more.
How to fix fungal acne
Fungal acne responds to antifungal treatments, not the same approach as regular acne. The most accessible first steps:
- Ketoconazole shampoo used as a face or body wash - leave on for 2-3 minutes before rinsing. Directly targets Malassezia. Over-the-counter 2% ketoconazole shampoo is available at most pharmacies in India.
- Zinc pyrithione (found in some shampoos and cleansers) also has antifungal properties.
- Reducing fatty acid-rich products during a flare gives the skin a chance to reset.
- Keeping skin dry and cool - especially after sweating - removes the environmental conditions that allow Malassezia to overgrow. Changing pillowcases more frequently and keeping hair off the face during monsoon both help.
If the flare doesn't improve within 4-6 weeks of consistent antifungal care, a dermatologist can prescribe oral antifungals for more persistent cases.
Building a monsoon routine for congested, acne-prone skin
Morning:
- Gentle, non-foaming or low-lather cleanser (avoid anything drying)
- Niacinamide serum - regulates oil, anti-inflammatory
- Lightweight, non-comedogenic moisturiser (gel-based preferred for monsoon humidity)
- SPF 50 PA++++ - choose a formula labelled non-comedogenic and fungal-acne-safe
Evening:
- Gentle cleanser (double cleanse if you used sunscreen - micellar water first, then face wash)
- BHA (salicylic acid 2%) - 2-3 times per week only, not daily
- Niacinamide or a barrier-repair serum on off-BHA nights
- Lightweight moisturiser - check ingredient list for fatty acid triggers if fungal acne is a concern
Keep actives to a minimum during a flare. The goal is to treat, not layer more.
Frequently asked questions
How do I know if I have fungal acne or regular acne?
Fungal acne tends to appear as small, uniform, itchy bumps in clusters, often on the forehead, hairline, or chest. Regular acne produces varied bumps - whiteheads, blackheads, cysts - that don't itch and aren't clustered uniformly. If your acne doesn't respond to typical acne treatments after 6-8 weeks, fungal acne is worth considering.
Can I use salicylic acid for fungal acne?
Salicylic acid alone won't treat fungal acne because it doesn't address the Malassezia yeast. It might reduce inflammation slightly, but it won't clear the underlying cause. For fungal acne, you need an antifungal - ketoconazole is the most accessible option in India.
Does sunscreen cause fungal acne?
Some sunscreens do. Sunscreens containing fatty acid-rich emollients or certain esters can feed Malassezia. If you notice flares near hairlines or on areas where sunscreen is applied, the formula might be contributing. Look for sunscreens labelled non-comedogenic and check ingredient lists for fatty alcohol and oil content.
Can fungal acne and closed comedones appear at the same time?
Yes. This is actually common in monsoon. High humidity drives Malassezia overgrowth while excess sebum and heat lead to pore congestion. You may need to address both simultaneously with a BHA for comedones and an antifungal for the fungal component.
Is niacinamide safe to use when I have fungal acne?
Yes. Niacinamide is considered Malassezia-safe and is a useful ingredient during a fungal acne flare. It won't worsen the condition and helps regulate oil production, which removes one of the environmental factors that feed fungal overgrowth.
How long does it take fungal acne to clear?
With consistent antifungal treatment, most people see improvement within 3-4 weeks. Complete clearing can take 6-8 weeks. Reintroducing triggering ingredients before the skin fully settles is the most common reason for relapses.
Should I stop moisturising if I have closed comedones?
No. Skipping moisturiser doesn't help closed comedones and can make things worse by disrupting the skin barrier. The key is choosing the right moisturiser - lightweight, gel-based, non-comedogenic - rather than eliminating it entirely.
What's the single most important change for monsoon-prone congestion?
Switch to a lighter moisturiser and sunscreen. Most skin that becomes more congested in monsoon is responding to products that are too heavy for the season's humidity. A product that worked well in winter may be contributing to congestion in June.
