Charleston Humidity: Is SPF Breeding Skin Mold?
By Franklin Everett ShawCharleston summers: a beautiful blend of history, charm, and humidity so thick you can practically wear it. But that humidity, combined with our best intentions to protect our skin, can create a perfect storm – a breeding ground for what some affectionately (and not so affectionately) call “skin mold,” otherwise known as fungal acne. It’s time to ditch the vague advice and get real about sunscreen and fungal acne in the Lowcountry.
The culprit? Malassezia, a type of yeast that naturally lives on our skin.
Normally, it’s harmless.
However, in warm, humid environments, and under occlusive conditions, it can overgrow, leading to those tiny, itchy bumps that resemble acne but don’t respond to typical acne treatments.
Think of it like this: Charleston’s air is already saturated with moisture.
Then, we slather on a thick, pore-clogging sunscreen.
That sunscreen acts like a plastic wrap, trapping sweat, oil, and humidity against our skin.
Malassezia thrives in this environment.
So, what’s a sun-conscious Charlestonian to do? We can’t exactly skip sunscreen – the sun here is no joke.
The answer lies in smart choices and diligent skincare.
First, ditch the heavy, comedogenic sunscreens.
Many traditional sunscreens contain ingredients like coconut oil, shea butter, and certain fatty acids that Malassezia loves to feast on.
These ingredients are often labeled as “moisturizing” or “nourishing,” which sounds great, but can be disastrous for fungal acne-prone skin.
Instead, look for sunscreens specifically labeled as “non-comedogenic,” “oil-free,” and “formulated for sensitive skin.”
Even better, search for sunscreens that are specifically marketed as “fungal acne safe.”
These often contain ingredients like zinc oxide or titanium dioxide as the active UV filters, and avoid the problematic oils and esters.
A great example is the EltaMD UV Clear Broad-Spectrum SPF 46.
While not specifically marketed for fungal acne, it’s a favorite among dermatologists and skincare enthusiasts for its lightweight, oil-free formula.
Another option is the La Roche-Posay Anthelios Melt-In Sunscreen Milk.
While it does contain some fatty alcohols, many people with fungal acne find it tolerable due to its overall formulation and the fact that it’s designed to be very lightweight.
Double cleansing is your friend.
Charleston’s humidity and pollution mean that sunscreen, sweat, and grime build up on your skin throughout the day.
A single cleanse often isn’t enough to remove it all.
Start with an oil-based cleanser to dissolve sunscreen and makeup.
Follow with a gentle, water-based cleanser to remove any remaining residue.
This ensures that your pores are truly clean and that Malassezia doesn’t have a feast waiting for it.
For an oil cleanser, consider something like the DHC Deep Cleansing Oil.
It’s a classic for a reason, effectively removing makeup and sunscreen without stripping the skin.
For a second cleanser, the CeraVe Hydrating Facial Cleanser is a solid, gentle option.
Consider incorporating an anti-fungal cleanser into your routine.
This doesn’t have to be an everyday thing, but using a cleanser containing ingredients like ketoconazole or selenium sulfide a few times a week can help keep Malassezia in check.
Nizoral shampoo, yes, the dandruff shampoo, contains ketoconazole and can be used as a face wash.
Just be careful to avoid the eye area and don’t leave it on for more than a few minutes.
Another option is a selenium sulfide wash, like Selsun Blue.
Again, use with caution and avoid the eye area.
Don’t forget about your body.
Fungal acne isn’t just a facial problem.
It can also appear on the chest, back, and shoulders, especially in areas where clothing traps sweat.
Use the same principles for your body as you do for your face: non-comedogenic body wash, lightweight moisturizers, and occasional anti-fungal treatments.
Be mindful of your clothing.
Tight-fitting clothing, especially synthetic fabrics, can trap sweat and create a humid environment that encourages Malassezia growth.
Opt for loose-fitting, breathable fabrics like cotton or linen, especially during workouts or hot days.
Address the underlying cause.
While topical treatments can help manage fungal acne, it’s important to address any underlying factors that might be contributing to the overgrowth of Malassezia.
This could include:
- Diet: Some people find that reducing their intake of sugary and processed foods can help.
- Stress: Stress can weaken the immune system, making you more susceptible to fungal infections.
- Medications: Certain medications, like antibiotics, can disrupt the balance of bacteria on your skin, allowing Malassezia to thrive.
A word of caution:
Fungal acne can be tricky to diagnose and treat.
If you’re unsure whether you have fungal acne or something else, consult a dermatologist.
They can perform a skin scraping to confirm the diagnosis and recommend the most appropriate treatment plan.
Common mistakes and pitfalls:
- Misdiagnosing fungal acne as regular acne: This leads to using ineffective treatments and potentially worsening the condition.
- Over-exfoliating: While exfoliation can help remove dead skin cells, overdoing it can irritate the skin and disrupt its natural barrier, making it more susceptible to fungal infections.
- Using comedogenic products: As mentioned earlier, this is a major culprit in triggering and exacerbating fungal acne.
- Ignoring the environment: Charleston’s humidity is a constant factor, so it’s important to be proactive about managing it.
- Giving up too soon: Fungal acne can take time to clear up, so be patient and consistent with your treatment plan.
Living in Charleston doesn’t mean you have to choose between sun protection and clear skin.
By making smart choices about your sunscreen, skincare routine, and lifestyle, you can enjoy the Lowcountry’s beautiful weather without sacrificing your complexion.
Remember, it’s about finding the right balance and being proactive about managing the unique challenges that our humid environment presents.
So, go forth, enjoy the sunshine, and keep that “skin mold” at bay!
