What Causes Acne? Myths & Main Causes
If you suffer from acne, you've probably heard it all: “Your skin is dirty.” “It's the greasy food.” “It's stress.” “It's makeup.” “It's because you touched your face.”
These theories are everywhere, and some are simply rude while the rest are wildly oversimplified. So, what causes acne? Before we get to the real culprits, it helps to clear up the myths. Acne is frustrating enough without misinformation making it harder to understand.
Common Acne Myths, Explained
Acne myths tend to stick because they offer simple explanations for those seeking answers. The truth is, unfortunately, a bit more complicated, and while less convenient, it’s far more useful. Here are three of the most common theories about breakouts, and what is actually true.
MYTH #1: Your Skin Is Dirty
MYTH #2: Greasy Food Causes Pimples
Let’s get this straight: oil from greasy food does not travel from your plate to your pores to create a breakout. That said, diet may play a role for some people. Certain high-glycemic foods or dairy products may be linked to breakouts in some individuals, but acne is not typically caused by one meal, one snack or one slice of pizza.
The more intelligent approach is observation. If you notice your skin reacts after consistently eating certain foods, make note of that as skin will report back.
MYTH #3: Stress Is the Whole Story
Stress can contribute to breakouts, but it’s rarely the entire explanation.
If you are having an especially stressful week and noticing corresponding breakouts, stress may certainly be one factor. But acne usually involves more than one trigger. It is not simply caused by mood swings or busy calendars, instead it is a biological process happening within your pores in response to something bigger.
What Is Acne & What Are the Causes?
Acne is a common inflammatory skin condition that begins inside clogged pores.
Oil, dead skin cells and other debris can become trapped, creating the conditions for acne-causing bacteria and inflammation to take hold. This can lead to visible blemishes. Put simply: acne starts with congestion, then escalates.
There are three main causes of acne, none of which have to do with a lack of hygiene, will power or self-care.
COMMON CAUSE #1: Excess Oil & Dead Skin Buildup
Sebum is the skin’s natural oil, and it is not the enemy. Skin needs oil to maintain moisture, support its barrier and defend against environmental aggressors for overall skin health. The problem begins when excess oil mixes with dead skin cells and becomes trapped inside your pores. This buildup can prevent pores from clearing normally, creating the congestion that often leads to breakouts.
COMMON CAUSE #2: Acne-Causing Bacteria
Like sebum, bacteria are essential for overall skin health. Both good and bad bacteria naturally live in your skin, helping form a protective shield against germs. When bad bacteria become trapped inside already congested pores, it can multiply as they thrive in a low-oxygen, oily environment. This perfect storm of acne-causing bacteria overgrowth ultimately leads to breakouts.
COMMON CAUSE #3: Inflammation
Acne Face Map: Acne Causes Based on Their Location
Where the breakout is located on your face can help offer clues as to what the cause may be, whether you’re looking for what causes forehead acne or what causes chin acne. Here are some common associations depending on where you notice those pesky bumps:
T-zone (forehead, nose & chin): This area has a much higher concentration of sebaceous glands than other parts of your face, making them especially prone to oil production.
Hairline: Haircare products, styling creams, oils, hats, helmets, headbands and workout sweat can all contribute to congestion around the hairline and upper forehead.
Cheeks: Breakouts on the cheeks are typically caused by clogged pores from cosmetic products.
Jawline & chin: Aside from oil, chin and jawline breakouts are also commonly associated with hormonal fluctuations, which is why they may appear around a menstrual cycle or during other hormonal shifts.
Of course, while the location of a breakout can offer clues, it’s not a final verdict as there’s no one-size-fits all for acne causes.
The Takeaway: How to Determine Why You Are Breaking Out
The honest answer: Acne rarely has one neatly determined cause, which is what makes it so stubborn and, therefore, frustrating.
Most often, it’s a combination of factors. You may be producing more oil than usual. Dead skin cells may be building up inside your pores. Hormonal shifts may be involved. Sweat, friction or haircare residue may be causing congestion. Inflammation may be making everything look and feel worse.
The good news is, regardless of the reason for your breakouts, there’s a regimen that will target all three of the most common causes: Acne Relief. Featuring a non-drying, soothing cleanser, a gentle exfoliating toner, maximum-strength clearing and spot treatments and a calming clay mask, it’s strategically formulated to safely yet effectively target excess oil, acne-causing bacteria and inflammation.
So you can spend less time trying to figure out “why,” and more time fighting flare-ups with targeted solutions for consistently clear-, balanced- and healthy-looking skin over time.
