Dermatologists Use This 1 Trick To Help Figure Out What's Causing Your Acne

Whether you have onepimple or a bunch, it’s never a sight you want to see. Sometimes it seems like no matter how much youwash your face or how muchacne treatment you use, acne just won’t go away. And if you’re not a teenager, it’s especially frustrating trying to figure out the source of the breakouts.

Dermatologists are here to help with that last issue. A key trick to finding the cause of acne, they said, is noting where the breakout is located on your face — it’s called facial mapping. This method may not be 100% accurate all of the time, but it’s often a good starting point. 

Let’s break it down by each area of the face.

Forehead

Forehead pimples can pop up for a few reasons.

“Excess oil production is the main cause, followed by stress,” saidDr. Roger Kapoor, a Harvard-trained dermatologist who’s the senior executive vice president of Beloit Health System in Beloit, Wisconsin. “Watch out for things that can clog pores, such as headbands, hats, helmets and even hair products.”

When hair products clog pores, the acne you’ll see is typically a small bump, either a whitehead or blackhead, according to Dr. Ruth McTighe, a board-certified dermatologist at Waccamaw Dermatology in Mount Pleasant, South Carolina.

The good news is you don’t have to give up those products completely. “To prevent this, avoid letting hair products come into contact with these areas; for example, wearing a headband when applying them can help,” said Dr. Michelle Henry, a board-certified dermatologist who trained at Harvard and is the owner and founder of Skin & Aesthetic Surgery of Manhattan. That way, you further delineate your hairline from your face.

Makeup is another consideration. “There’s also pomade acne, which is due to the use of heavy oils, waxes and comedogenic makeup on or around the face,” Henry said. “Oftentimes, acne is just kind of random, but when you’re seeing acne solely on the forehead, it could be due to any of the above reasons.”

Kapoor said this forehead acne will last several weeks, on average. The effective treatment options he recommended are over-the-counter salicylic acid and adapalene 0.1% cream.

Cheeks

Cheek acne can stem from various contributors, such as bacteria, diet and rosacea. Let’s break each one down. 

Bacteria comes from various sources: tobacco smoke, a dirty pillowcase, your makeup brush, your cellphone screen, chin straps (like from a bike helmet) and medical masks (aka “maskne”). 

As far as foods and drinks go, it’s a bit more complicated. “While research persists and no direct link has been established between certain foods and acne, we know that diet can contribute to and even result in acne in some people,” Kapoor said, noting his clients have seen a link. “Food does not universally cause acne but is something I advise all my clients to be aware of and take action.” 

More specifically, he recommended keeping a food diary and seeing if you can draw patterns between acne flare-ups and eating sugary foods or caffeine-filled drinks.

Last but not least, let’s talk about rosacea. McTighe said this skin condition may look like acne on your upper cheeks. “Acne-like bumps in these areas may be a sign ofrosacea, or acne rosacea, often accompanied by background redness and flushing,” she said.

Rosacea is a type of inflammatory lesion that can be treated with low-dose oral antibiotics, topical antibiotics or other targeted skin care products.

Cheek acne typically lasts about as long as forehead acne, according to Kapoor. (So several weeks, on average.)

However, the treatment options he mentioned differ from the treatments for forehead acne: Experts recommend over-the-counter products that contain benzoyl peroxide or a topical antibiotic, such as topical clindamycin. “Products that help clean and sterilize the skin generally help,” Kapoor summarized.

Jawline

The main contributor to jawline acne is hormonal fluctuations, so women may notice more pimples around their period, for example. This acne is cyclical and may last a few weeks.

Henry tied this type of acne to androgens (which are known as the “male” hormones, though women have some of it, too). She’s seen it in people who are menstruating, have polycystic ovarian syndrome (PCOS), are pregnant or are experiencingmenopause. Basically, people typically experience hormonal fluctuations — including an increase in androgen — at those times. Androgens stimulate sebum production, which can lead to breakouts.

“The jawline is really the only part of the face where we think that acne is linked to internal issues,” she added, noting jawline acne is especially well-researched.

So what’s the treatment? It depends on the person, of course, but Kapoor said options include over-the-counter hormonal therapy, such as birth control, as well as prescription products, such as azelaic acid, dapsone gel and spironolactone. Henry added a topical medication called Winlevi, which interferes with the receptors that hormones use to flare acne.

Nose 

Acne on the nose (and/or ears, actually) is another sign of excess oil production that usually lasts a few weeks.

“There is nothing specific about nose acne except for the fact that this tends to be the oiliest part of the face,” Henry said.

As far as treatment goes, Kapoor believes retinoids are the most effective option. “Over-the-counter adapalene 0.1% can be a nice starting point, but if needed, prescription-based retinoid products can potentially offer more aggressive results.”

Mouth Area

If you notice zits around your mouth, consider what products you’ve been using. 

“Usually, we see acne around the mouth due to an outside trigger,” Kapoor said. “Triggers could include residual toothpaste, as the fluoride in toothpaste can irritate the skin, lip balms and topical hydrocortisone use.”

These bumps are typically small and itchy, McTighe said, and may also be around your eyes. Typically, they indicate perioral dermatitis. “This condition can be triggered by topical or inhaled corticosteroids, intolerance to certain cosmetic products or medications, and other factors.”

Mouth acne lasts around a few weeks, but can persist if you don’t address that trigger, Kapoor said. Further, topical metronidazole or azelaic acid, along with oral antibiotics, can hurry the process along.

Another Quick Note On Effective Treatment

Treatment depends on the type of acne, not just where it’s located.

“If it is more comedonal, you’re going to want to use a retinoid or a salicylic acid — products that are going to help exfoliate and unclog the pores,” Henry said. “If the acne is more inflammatory, you may want to use benzoyl peroxide, topical antibiotics or sulfur washes — products that are more anti-inflammatory and antibacterial.”

Comedones typically look like small, rough bumps that are either flesh-colored, white or dark. Inflammatory acne, on the other hand, entails red, swollen bumps that are often painful.

But per usual, your best bet is to see a dermatologist. Bodies are complex, acne doesn’t always make sense and what works best for one person might not work as well for another.

Promising Target review: "I don't break out much usually, but I got some bad cystic acne on my chin the other day (pretty sure it was stress acne rip). But I got these yesterday, and after 2 patches (one overnight, one in the day), it's basically all gone! They stay on very well and weren't too noticeable imo (I have fair skin, they are translucent white, so that probably won't be the case deeper skintones). I just have one small, mostly flat bump left that I could probably knock out with a single microneedle patch. These seriously work! :D" – emy

Great for all ages and stages of skin breakouts. Definitely recommend this product and this brand as being reliable and very effective! It’s my go to!" – Laura

Promising Amazon review: "This is my go to pimple patch. I have been using it for many years and always have extra in the house. I usually put it overnight on clean skin( no toners ) and leave it there. It’s not water proof but if you use it on your body you can totally keep it for couple days and even take shower with it, it won’t come out. Works best if your pimple about to pop or already did and needs a little more drying. Highly recommend!" — Galina B.

The hydrocolloid polymer is also infused with time-honored ingredients like retinol and aloe vera leaf extract for soothing benefits.

Promising Ulta review: "I've used hydrocolloid patches from a well-known K-beauty brand before and was never very impressed with the results. Ordered these Peace Out ones on a whim thinking they were overpriced and probably wouldn't do much but might as well try. This morning I woke up with a huge pimple on my cheek so I decided to test these out and washed my face and stuck one on. First off, they stick super well compared to the other brand I tried. Second, and most importantly, it started absorbing the gunk almost immediately. I took it off after four hours to see the results and my pimple had decreased significantly in size and redness. I applied another one just to be safe but its barely noticeable at this point. Will reach for these in the future!" — Christine
