What Causes Acne? Understanding the Root vs. Surface Triggers
You’ve probably heard that acne is linked to bacteria—specifically Cutibacterium acnes (C. acnes)—or that hormones are to blame. So which is it? The truth is, acne usually has both surface triggers and deeper root causes.
Surface triggers are what actually happens on your skin. For example, C. acnes bacteria inflaming pores is a direct, visible cause. But why these bacteria act up on your skin and not someone else’s often comes down to deeper factors—most commonly hormonal changes.
Here are some of the most common deeper causes of acne:
Hormonal fluctuations: Androgens and insulin can drive breakouts. Many notice flare-ups before menstruation, or hormone tests may show high-normal androgens paired with lower estrogen.
Inflammation: Higher systemic inflammation, often linked to gut health, can trigger acne.
Stress: Work, school, or life stress can worsen breakouts.
Physical irritation: Friction from hats, backpacks, or tight clothing can cause localized acne.
Sensitivity or allergies: Makeup, irritating ingredients, certain foods, medications, or other allergens can contribute.
Even if you don’t identify a specific deeper cause, acne develops through similar processes on the skin. Targeted, science-backed skincare routines—including effective Korean skincare solutions—can help control breakouts. And if you address both surface triggers and deeper causes with lifestyle or dietary adjustments, your chances of clear, healthy skin increase significantly.
How Acne Forms: What’s Happening on Your Skin
Understanding how acne develops can make it feel less confusing—and give you the tools to tackle it more effectively. Here’s what typically happens on your skin:
Pores become clogged: Inside your pores, skin cells naturally shed, but in acne-prone skin this process can be uneven. Dead cells stick together and, combined with excess oil (often thicker than usual), can form a plug that blocks the pore. These clogged pores are called comedones—when the opening is exposed to air, it oxidizes and becomes a blackhead.
Bacteria multiply: The clogged, oil-rich, low-oxygen environment is a perfect home for bacteria, especially C. acnes, a major contributor to inflamed acne. Once established, these bacteria multiply rapidly.
Immune response and inflammation: Your immune system reacts to the bacterial growth by sending white blood cells to fight the infection. The result is inflammation, which is essentially a mix of bacteria, immune cells, and debris. If the pressure inside the pore builds too much, the pore can rupture, forming a large, red, inflamed pimple.
It might sound complicated, but don’t worry—this process happens the same way for everyone. The good news is that with gentle, targeted skincare, thoughtful routines, and some Korean skincare favorites, you can help calm your skin, prevent breakouts, and feel more confident in your own skin. Next, we’ll look at common acne myths and what not to do when managing breakouts.
Common Acne Myths That Make Things Worse
There’s no shortage of acne myths out there, and many so-called “quick fixes” might seem helpful at first—but often make breakouts worse in the long run. Be smart and don’t fall for these misconceptions!
Myth #1: You can “dry out” your acne.
Drying out your skin doesn’t actually treat the acne itself—it only strips your skin of moisture, which is essential for healing and fighting inflammation. Over-drying can disrupt your skin’s natural balance, making it easier for bacteria to thrive. Gently blotting excess oil is very different from harshly drying out your skin with aggressive products.
Myth #2: Acne is caused by dirt on your skin.
Over-cleansing with harsh soaps or scrubs might feel satisfying, but it actually increases irritation and dryness, which can worsen breakouts. Scrubbing the skin can cause tiny injuries, inflammation, and even spread bacteria more evenly across your face. Forget aggressive cleansers, scrubs, and foaming soaps—gentle cleansing is key.
Myth #3: You can only treat pimples locally.
Spot treatments like Salicylic Acid (BHA) or Benzoyl Peroxide can reduce redness and swelling, but they don’t address the root cause. Treating only visible pimples leaves other developing breakouts untouched. Local treatments can help if you have occasional, mild acne—but if your breakouts are persistent, it’s better to focus on deeper causes and a consistent routine.
Myth #4: If it stings or tingles, it’s working.
There’s no scientific evidence that ingredients that sting or tingle—like alcohol, menthol, peppermint, eucalyptus, or lemon—actually help acne or oily skin. In fact, irritation can worsen your skin by triggering nerves in the pores, which increases oil production and can make breakouts worse.
Understanding these myths is the first step to a smarter, more effective acne routine—one that calms your skin instead of stressing it out.
What NOT to Do When Treating Acne
Managing acne isn’t just about what you should do—it’s equally important to know what to avoid. Doing the wrong things can make breakouts worse or slow down healing. Here’s what to skip:
Avoid harsh or irritating products: Acne-prone skin is sensitive skin. Gentle, calming skincare is key—strong or aggressive formulas can trigger more irritation and inflammation.
Don’t wash with soap or solid cleansers: Soap can clog pores, dry out your skin, and create a high pH environment that encourages bacteria growth. If your skin is acne-prone, skip the soap entirely.
Don’t pick or squeeze pimples: Touching or popping your pimples can increase inflammation and lead to scarring. If a pimple opens easily on its own, you may gently clean it, but never force it—how you handle it can make the difference between quick healing and long-term marks.
Avoid extremely hot or cold water: Hot compresses or ice won’t make pimples disappear or “open/close” your pores. In fact, they can worsen inflammation. Stick to lukewarm water for cleansing and treatments.
Skip alcohol-heavy toners and products with irritating ingredients: Menthol, eucalyptus, citrus extracts, and strong fragrances are not friends to sensitive or acne-prone skin. They can increase irritation rather than help your breakouts.
Following these “don’ts” helps your skin stay calm, reduces inflammation, and sets the stage for effective acne-fighting treatments.
Proven Steps to Fight Acne Effectively
Now let’s get to the heart of it: how to tackle your acne. The key is to interrupt the breakout process at multiple steps with targeted, effective ingredients and routines.
1. Minimize Pore Clogging (BHA & Exfoliants)
BHA (Salicylic Acid): An oil-soluble chemical exfoliant, BHA is a gold standard for acne-prone, clogged, or blackhead-prone skin. It penetrates pores to normalize cell turnover and reduce inflammation. Use a 1–2% BHA liquid as a toner once daily (morning or evening). Choose an alcohol-free, gentle formula to avoid irritation.
Retinoids: Retinoids are highly effective not only for anti-aging but also for acne. In fact, they were originally developed specifically to treat acne, helping keep pores clear and prevent breakouts by preventing dead skin cells from sticking together and forming clogs. If you’re younger, start with BHA; if anti-aging is also a concern, a retinoid is a great choice. You can combine them carefully—e.g., BHA in the morning and retinoid at night, or BHA followed by a retinoid serum in the evening—while monitoring for irritation. Some retinoids, like retinal, also have antibacterial effects.
Niacinamide: Helps regulate oil production, reduce pore size, and calm inflammation. Safe to use alongside BHA and retinoids, morning or evening, even twice daily.
Zinc PCA, Sarcosine, and other sebum-regulating ingredients: While overactive oil production is best treated medically, these ingredients can modestly support oil control and complement your main actives.
Here are some gentle yet powerful Korean skincare products designed to minimize clogged pores and support clearer skin:
2. Fight C. acnes Bacteria
Benzoyl Peroxide (BP): Highly effective for inflamed acne, this ingredient is prescription-only in Korea, widely available in the US, and usually pharmacy-only in the EU. Start with 5% to minimize side effects. Pair it with pore-clearing actives like BHA for best results, but be mindful of dryness and possible pro-oxidant effects with long-term use.
Azelaic Acid: A gentler alternative to BP, effective at reducing inflammation, regulating pore cell behavior, and fighting C. acnes. Can be used alone or after a short BP course.
Sodium Ascorbyl Phosphate (SAP): A stable vitamin C derivative that helps combat C. acnes without irritating or aging the skin. Works synergistically with retinoids.
Retinal: Certain retinoids, like retinal, also have antibacterial effects and can support home acne routines.
Zinc PCA: In addition to regulating oil, it has mild antibacterial effects, making it a helpful adjunct ingredient.
By focusing on both pore-clearing and antibacterial steps—and combining key actives thoughtfully—you can interrupt the acne process on multiple levels, calm inflammation, and support healthier, clearer skin.
Many Korean skincare products are perfect for acne-prone skin, as they help fight C. acnes bacteria and support a clearer complexion:
3. Reducing Inflammation
Remember: acne is an inflammatory condition, so treating your skin gently is just as important as the active ingredients you use. Anti-inflammatory ingredients complement acne treatments and help calm the skin.
Some ingredients already mentioned—BHA (salicylic acid), Azelaic Acid, and Niacinamide—also reduce inflammation. Additionally, any gentle, fragrance-free, alcohol-free, and essential-oil-free serum or moisturizer with anti-inflammatory properties can support your routine. Look for ingredients like Beta-Glucan, Madecassoside (Cica), Panthenol, or Allantoin—they soothe the skin while also providing hydration.
Use a gentle, pH-balanced cleanser, and if you’re using Benzoyl Peroxide, don’t forget proper hydration. Dry, under-hydrated acne-prone skin struggles to heal, so maintaining a healthy skin barrier is crucial.
Finally, despite common myths, sun exposure is not beneficial for acne. It may temporarily make blemishes less visible on tanned skin, but UV rays do not improve acne and can harm your skin long-term. Protect your skin daily with sunscreen.
These Korean skincare products can help soothe inflamed acne while supporting your skin’s natural balance:
Diet Tips for Managing Acne
Diet can play a role in managing acne, especially hormonal and inflammatory types. While there’s no “miracle food” or universally “bad food,” certain habits can make a noticeable difference.
Choose low-GI carbohydrates: Foods like whole grains, legumes, and vegetables help avoid blood sugar spikes that can worsen hormonal acne.
Increase omega-3 intake: Fatty fish, flaxseeds, chia, or omega-3 supplements help reduce inflammation and support skin health.
Limit dairy if needed: Milk and dairy products may aggravate hormonal acne in some people; reducing them for a few weeks can reveal their impact.
Other helpful strategies:
Zinc supplements: 30 mg daily can reduce inflammatory acne by roughly 30% over three months when combined with a proper skincare routine.
Pre- and probiotics: Supporting gut health with supplements or fermented foods like kefir, kimchi, and kombucha may improve inflammatory acne.
A balanced, anti-inflammatory diet—low in high-GI carbs, rich in omega-3s, and mindful about dairy—can complement your skincare routine and help your skin look its best.
When Over-the-Counter Products Fail: Next Steps
If you’ve followed the right routines but acne persists, prescription-strength ingredients may help. Here’s a concise overview:
Topical antibiotics (erythromycin, clindamycin):
Reduce acne-causing bacteria and inflammation; often combined with benzoyl peroxide for stronger results.
High-concentration azelaic acid:
Targets bacteria, reduces inflammation, and helps normalize skin cell turnover; generally gentle even at higher strengths.
Topical retinoids (adapalene, tretinoin):
Keep pores clear, prevent clogged cells, and reduce new acne formation; stronger forms may cause dryness or irritation, so introduce gradually and maintain hydration.
Oral antibiotics (erythromycin, doxycycline, minocycline):
Effective for inflammatory acne, but long-term use may disrupt gut microbiota and can lead to bacterial resistance; low doses can reduce this risk.
Oral retinoids (isotretinoin):
Powerful for severe acne, reducing oil production, clogged pores, and inflammation; requires careful monitoring due to side effects like dryness, sun sensitivity, and teratogenicity.
Hormonal modulators (certain estrogen-progestin combinations):
Reduce androgen-driven oil production, improving acne in women; effects last only while in use and potential side effects should be discussed with a doctor.
Note: If you are pregnant or planning pregnancy, it’s crucial to be extra cautious with acne treatments. Many powerful ingredients like oral retinoids, high-strength topical retinoids, and certain oral antibiotics must be avoided, as they can harm your baby. Instead, focus on safer options and gentle routines.
