Pimples by zone: causes and fixes
For each zone, the causes dermatology sources describe, what to try first, and the look-alikes that acne products won’t fix.
Zone 01 · Face
Hairline pimples: causes
Tiny bumps right along the hairline usually point to hair products, or to hats and headbands that sit there.
Causes, what to try, look-alikes
Likely causes
Hair products. The AAD describes tiny bumps along the hairline or the upper forehead as a sign that hair products are clogging pores, a type of acne cosmetica. Oily products such as pomade can worsen acne, and a Cleveland Clinic dermatologist says mousse or dry shampoo “can build up at the hairline.”
Hats, caps and headbands. Gear that traps heat and sweat and rubs the skin can trigger breakouts (acne mechanica). DermNet lists pressure from headbands, and the AAD says to wash hats, caps and headbands that touched hair products.
What to try
Check everything that touches the area, including shampoo, conditioner and styling products, for “non-comedogenic”, “oil-free” or “won’t clog pores”. Or paste the ingredients into the pore checker.
Put styling products on the ends of your hair, away from the scalp, and keep hair off your face. Shampoo more often if your hair is oily.
Wash pillowcases, hats, caps and headbands that touched your hair products.
After you stop a pore-clogging product, give your skin 4 to 6 weeks to clear.
Could be something else
“Fungal acne”. Itchy bumps that all look the same size, with no blackheads, can be Malassezia folliculitis, a yeast infection of the hair follicles. It favors the chest, back, forehead, hairline, chin and neck.
Get help. If it hasn’t cleared about 6 weeks after you drop the product, see a dermatologist.
The forehead is oily, and it’s where hair, hair products and helmets meet the skin.
Causes, what to try, look-alikes
Likely causes
Oil glands and clogged pores. The forehead and nose have larger pores and more oil glands, which favors blackheads and whiteheads. Mayo Clinic lists the forehead among the oiliest areas of the body.
Your hair and hair products. The AAD says oil from your hair can cause acne on your forehead, and that hair products can cause tiny bumps on the upper forehead. Small pimples on the forehead are often this.
Helmets, caps and headbands. Helmets can trigger breakouts on the forehead by trapping heat and sweat against the skin (acne mechanica).
Makeup. Makeup that clogs pores shows up as many tiny bumps on the forehead, cheeks and chin.
What to try
Put styling products on the ends of your hair, away from the scalp, and keep hair off your face. Shampoo more often if your hair is oily.
Salicylic acid (0.5–2% over the counter) opens clogged pores, which suits blackheads and whiteheads. Pairs: with benzoyl peroxide, with adapalene.
Adapalene 0.1% gel, a retinoid sold without a prescription, once a day on the whole area, not just the spots. Retinoids work best as long-term maintenance. Using it with benzoyl peroxide?
Put clean, soft padding between helmets or chin straps and your skin, and wear moisture-wicking, loose clothes.
Use makeup labeled oil-free, non-comedogenic or won’t clog pores, and take it off before bed. After you stop a product, improvement can take 4 to 8 weeks.
Could be something else
“Fungal acne”. Itchy bumps that all look the same size, with no blackheads, can be Malassezia folliculitis, a yeast infection of the hair follicles. It favors the chest, back, forehead, hairline, chin and neck.
Seborrheic dermatitis. Scaly, greasy or flaky patches between and under the eyebrows, on the sides of the nose or on the forehead: flakes, not pimples.
Get help. If it isn’t better after 6 to 8 weeks of treatment, see a dermatologist.
No source we found names a cause specific to the temples. They sit at the hairline, so hair products and headgear are the first things to check.
Causes, what to try
Likely causes
Hair products and headgear. The temples border the hairline, where the AAD says hair products cause tiny bumps, and where helmets, caps and headbands press and trap sweat.
Part of a wider pattern. In a study of 374 adult women with acne, the temples were one of the zones where acne showed up, usually together with other zones rather than alone.
What to try
Check everything that touches the area, including shampoo, conditioner and styling products, for “non-comedogenic”, “oil-free” or “won’t clog pores”. Or paste the ingredients into the pore checker.
Put styling products on the ends of your hair, away from the scalp, and keep hair off your face. Shampoo more often if your hair is oily.
Put clean, soft padding between helmets or chin straps and your skin, and wear moisture-wicking, loose clothes.
Get help. If it isn’t better after 6 to 8 weeks of treatment, see a dermatologist.
Between the brows is part of the oily T-zone. Flaky patches there are usually not acne at all.
Causes, what to try, look-alikes
Likely causes
The oily T-zone. The forehead and nose form the T-zone, with larger pores and more oil glands, so blackheads and whiteheads are common here.
Plucking and waxing. Plucking or waxing can damage hair follicles and cause folliculitis, which looks like an acne breakout.
What to try
Salicylic acid (0.5–2% over the counter) opens clogged pores, which suits blackheads and whiteheads. Pairs: with benzoyl peroxide, with adapalene.
If you shave: shave when hair is soft, go in the direction it grows, and change disposable blades every 5 to 7 shaves. Bumps after plucking or waxing? Stop for 30 days.
Use makeup labeled oil-free, non-comedogenic or won’t clog pores, and take it off before bed. After you stop a product, improvement can take 4 to 8 weeks.
Could be something else
Seborrheic dermatitis. Scaly, greasy or flaky patches between and under the eyebrows, on the sides of the nose or on the forehead: flakes, not pimples.
Folliculitis. Infected hair follicles that look like a sudden breakout; each spot may have a red ring and itch. Tight clothing, hot tubs, shaving, plucking and waxing are common causes.
Get help. If the patches are flaky and itchy, or bumps keep coming back after grooming, a dermatologist can tell which it is.
Blackheads on the nose are about oil glands. Small red bumps around the nose and mouth can be something else.
Causes, what to try, look-alikes
Likely causes
Oil glands and large pores. The nose has larger pores and more oil glands, which favors blackheads and whiteheads (comedonal acne).
Masks and touching. Masks can cause breakouts, especially with makeup underneath, and touching your face throughout the day can make acne flare.
What to try
Salicylic acid (0.5–2% over the counter) opens clogged pores, which suits blackheads and whiteheads. Pairs: with benzoyl peroxide, with adapalene.
Don’t squeeze, especially deep lumps: it pushes what’s inside deeper and can scar. Spread treatment over the whole area instead.
Under a mask, skip makeup and use a fragrance-free, non-comedogenic moisturizer.
Could be something else
Perioral dermatitis. Small, red, acne-like bumps around the mouth, nose or eyes that may itch or burn. Using a steroid cream on the face for too long is a common trigger.
Rosacea. Acne-like bumps on redness across the nose and cheeks, often with easy flushing and stinging when you apply products.
Get help. See a dermatologist if bumps around your nose and mouth itch or burn, or come with redness and flushing: perioral dermatitis and rosacea need their own treatment.
Cheek breakouts are the hardest to read. Start with everything that touches them.
Causes, what to try, look-alikes
Likely causes
Location tells you little. “Cheeks don’t tell us much,” says a Cleveland Clinic dermatologist: genetics or chance can be enough.
Phones, pillowcases, brushes, hands. Possible culprits include a dirty phone, unwashed pillowcases and makeup brushes. Mayo Clinic lists pressure from phones as an acne risk factor, and the AAD says touching your face can make acne flare.
Makeup and masks. Pore-clogging makeup causes tiny bumps on the cheeks, and makeup under a mask is more likely to clog pores.
Adult acne. Cleveland Clinic says hormonal adult acne is actually most likely to appear on the cheeks.
What to try
Clean what touches your face: your phone, pillowcases and makeup brushes (the AAD says brushes every week). Keep your hands off your face.
Cheek skin dries and gets irritated easily: a Cleveland Clinic dermatologist suggests using acne products there every other day.
Benzoyl peroxide (2.5–10% over the counter) reduces acne bacteria and works best combined with another acne treatment. It bleaches fabric. Pairs: with adapalene, with niacinamide.
Use makeup labeled oil-free, non-comedogenic or won’t clog pores, and take it off before bed. After you stop a product, improvement can take 4 to 8 weeks.
Could be something else
Rosacea. Acne-like bumps on redness across the nose and cheeks, often with easy flushing and stinging when you apply products.
Get help. If your cheeks flush easily and sting with products, ask a dermatologist about rosacea before you add acne products.
Chin breakouts are often linked to hormones in adult women, but chin straps, masks and makeup cause them too, and location alone can’t prove a hormone link.
Causes, what to try, look-alikes
Likely causes
Hormones, mainly in adult women. The AAD lists stubborn acne on the lower face, including the chin and jawline, and breakouts that come predictably during your period as signs of hormonal acne. Mayo Clinic says flares are common a week before menstruation.
But location isn’t a test. In a study of 374 adult women with acne, 89.8% had it in several facial zones and only 11.2% on the jawline area alone. Chin acne is a clue, not a diagnosis.
Chin straps, masks, makeup. Helmet chin straps can cause breakouts on the chin, masks can cause acne, and pore-clogging makeup shows up on the chin too. Tiny bumps around the lips can come from lipstick or lip balm.
Cystic pimples on the chin. A Cleveland Clinic dermatologist says chin and jawline acne tends to be deeper, bigger and more inflamed. Deep, painful lumps (nodules or cysts) can’t be cleared with store-bought products and can scar.
What to try
Adapalene 0.1% gel, a retinoid sold without a prescription, once a day on the whole area, not just the spots. Retinoids work best as long-term maintenance. Using it with benzoyl peroxide?
Benzoyl peroxide (2.5–10% over the counter) reduces acne bacteria and works best combined with another acne treatment. It bleaches fabric. Pairs: with adapalene, with niacinamide.
Don’t squeeze, especially deep lumps: it pushes what’s inside deeper and can scar. Spread treatment over the whole area instead.
If a lower-face pattern doesn’t clear, ask a dermatologist about hormonal therapy: birth control pills or spironolactone, which the AAD says work well for acne along the jawline and lower face.
Under a mask, skip makeup and use a fragrance-free, non-comedogenic moisturizer.
Could be something else
Perioral dermatitis. Small, red, acne-like bumps around the mouth, nose or eyes that may itch or burn. Using a steroid cream on the face for too long is a common trigger.
PCOS. Acne together with scalp hair loss, new facial hair or darkened skin can be a sign of polycystic ovary syndrome, which needs treating first.
Get help. See a dermatologist for deep, painful chin lumps, for acne with new facial hair, scalp hair loss or irregular periods, or if it isn’t better after 6 to 8 weeks.
Jawline acne is the classic hormonal pattern in adult women, but shaving and straps cause look-alike bumps.
Causes, what to try, look-alikes
Likely causes
Hormones. The AAD says women with acne along the jawline and lower face tend to respond well to hormonal therapy, and lists stubborn lower-face acne as a sign of hormonal acne. Cleveland Clinic adds that teen boys often get jawline acne during growth spurts.
Shaving. Shaving can irritate hair follicles: razor bumps show up in the beard area, and shaving is a common cause of folliculitis.
Straps, phones and pressure. Chin straps, helmets and phones press and rub along the jaw, which can trigger breakouts (acne mechanica).
What to try
Adapalene 0.1% gel, a retinoid sold without a prescription, once a day on the whole area, not just the spots. Retinoids work best as long-term maintenance. Using it with benzoyl peroxide?
If you shave: shave when hair is soft, go in the direction it grows, and change disposable blades every 5 to 7 shaves. Bumps after plucking or waxing? Stop for 30 days.
If a lower-face pattern doesn’t clear, ask a dermatologist about hormonal therapy: birth control pills or spironolactone, which the AAD says work well for acne along the jawline and lower face.
Put clean, soft padding between helmets or chin straps and your skin, and wear moisture-wicking, loose clothes.
Could be something else
Razor bumps. Painful or itchy bumps in the beard area after shaving.
PCOS. Acne together with scalp hair loss, new facial hair or darkened skin can be a sign of polycystic ovary syndrome, which needs treating first.
Get help. If deep, tender jawline acne keeps coming back, a dermatologist can discuss prescription options, including hormonal therapy for women.
Neck breakouts follow what touches the neck: hair products at the back, collars and razors at the front.
Causes, what to try, look-alikes
Likely causes
Hair products. The AAD says hair products can cause tiny bumps along the back of the neck.
Collars and pressure. Mayo Clinic lists tight collars among the things whose friction or pressure can trigger acne.
Shaving. Razor bumps and folliculitis show up where you shave, including the beard area.
The lower-face pattern. In women, hormonal acne can reach the neck: the AAD mentions deep, tender acne on the lower face, jawline or neck.
What to try
Check everything that touches the area, including shampoo, conditioner and styling products, for “non-comedogenic”, “oil-free” or “won’t clog pores”. Or paste the ingredients into the pore checker.
If you shave: shave when hair is soft, go in the direction it grows, and change disposable blades every 5 to 7 shaves. Bumps after plucking or waxing? Stop for 30 days.
Give any acne treatment 6 to 8 weeks before you judge it; full clearing can take 3 to 4 months.
Could be something else
“Fungal acne”. Itchy bumps that all look the same size, with no blackheads, can be Malassezia folliculitis, a yeast infection of the hair follicles. It favors the chest, back, forehead, hairline, chin and neck.
Razor bumps. Painful or itchy bumps in the beard area after shaving.
Get help. See a dermatologist for deep, painful lumps or itchy bumps that don’t go away.
Chest breakouts are mostly about oil, sweat and clothes, and itchy same-size bumps there are often not acne.
Causes, what to try, look-alikes
Likely causes
Oil glands. The chest is one of the areas with the most oil glands, so acne often shows up there.
Sweat and tight clothes. Clothing that traps heat and sweat and rubs can trigger breakouts. The NHS suggests loose, breathable clothing for acne on the body.
Hormones. Hormonal acne can appear on the chest, and the AAD says spironolactone can treat stubborn hormonal acne on the face, chest and back.
What to try
Shower and change as soon as you can after sweating. Can’t shower? Wipe the area. Wash workout clothes after each use.
Wear loose, breathable clothes (cotton or sweat-wicking) and skip straps that rub: swap a backpack for a handheld bag.
A benzoyl peroxide wash, left on for 2 to 5 minutes before you rinse. The AAD says 5.3% is less likely to irritate, and 10% is the strongest you can buy without a prescription. It bleaches towels and sheets.
Adapalene 0.1% gel after your shower or at bedtime: with benzoyl peroxide it can improve results. How to use both.

Folliculitis. Infected hair follicles that look like a sudden breakout; each spot may have a red ring and itch. Tight clothing, hot tubs, shaving, plucking and waxing are common causes.
Get help. See a dermatologist for itchy bumps that don’t go away, or for deep, painful acne.
Back acne responds to two things: less sweat and rubbing, and a wash you leave on for a few minutes.
Causes, what to try, look-alikes
Likely causes
Oil glands. The upper back and shoulders have some of the most oil glands on the body.
Sweat, straps and seats. The AAD says anything that rubs your back can make back acne flare: backpack straps, tight workout clothes, even the back of a driver’s seat (acne mechanica).
Hormones. Hormonal acne can appear on the back, and spironolactone can treat it there too.

Folliculitis. Infected hair follicles that look like a sudden breakout; each spot may have a red ring and itch. Tight clothing, hot tubs, shaving, plucking and waxing are common causes.
Get help. If you don’t see a difference in 6 to 8 weeks, or the acne is deep and painful, see a dermatologist.
Popular face charts link breakouts in each zone to a problem inside the body, from digestion to an “angry” liver. A fact check found the claim “is not proven by modern science or medicine,” and a Weill Cornell dermatologist told it face mapping “is not based on robust clinical trials and should not be used in the diagnosis or treatment of skin conditions.”
We searched for one and found no peer-reviewed study that ties a spot on the face to an internal organ. Acne comes from oil, clogged hair follicles, bacteria and inflammation, and it gathers where oil glands are densest: the face, forehead, chest, upper back and shoulders.
“Most dermatologists don’t physically ‘map’ people, but we do recognize various zones of the face,” says Cleveland Clinic dermatologist Amy Kassouf. A zone hints at what touches the skin, where oil glands cluster, or a hormonal pattern.
In a study of 374 women aged 25 and over, 89.8% had acne in several facial zones (cheeks, forehead, jawline area, temples). Only 11.2% had it on the jawline area alone, and they were less likely to have moderate or worse acne. The authors concluded that the stereotype of adult female acne as hormone-driven, inflammatory acne didn’t fit most of the women in the study.
After using an acne product: faintness, trouble breathing, swelling of the eyes, face, lips or tongue, or a tight throat. Get emergency help. Ordinary redness, irritation or itching where you applied it is not the same thing.

Questions people ask
What causes chin breakouts?
In adult women, stubborn acne on the chin and jawline, especially if it flares predictably around your period, is one sign of hormonal acne, according to the American Academy of Dermatology. But chin straps, masks and pore-clogging makeup can cause chin breakouts too, and in a study of 374 adult women only 11.2% had acne limited to the jawline area. Location is a clue, not proof.
Why do I get pimples on my cheeks?
Cheeks are the hardest zone to read: a Cleveland Clinic dermatologist says they “don’t tell us much.” Start with what touches them: your phone, pillowcases, makeup brushes and hands. Cleveland Clinic also notes that hormonal adult acne is most likely to appear on the cheeks. If your cheeks flush and sting with products, ask a dermatologist about rosacea.
What causes pimples on the forehead?
The forehead has larger pores and more oil glands, so blackheads and whiteheads are common. The AAD adds that oil from your hair can cause forehead acne, hair products can cause tiny bumps on the upper forehead, and helmets can trigger breakouts there by trapping heat and sweat.
Are jawline pimples hormonal?
Often, in adult women: the AAD lists stubborn acne on the lower face, chin and jawline as a sign of hormonal acne and says women with this pattern tend to respond well to hormonal therapy. In people who shave, bumps along the jaw can also be razor bumps or folliculitis.
What does a cystic pimple on the chin mean?
Deep, painful lumps are nodules or cysts, the most severe kind of acne. The AAD says store-bought products can’t clear them and they often scar, so see a dermatologist. Don’t squeeze them: that pushes the contents deeper.
Why do I get pimples around my nose?
The nose has large pores and many oil glands, so blackheads are common. Small, red bumps around the nose and mouth that itch or burn can be perioral dermatitis, often after using a steroid cream on the face, and bumps on redness across the nose and cheeks can be rosacea. Both need a dermatologist’s treatment.
What are the small pimples along my hairline?
The AAD describes tiny bumps along the hairline or upper forehead as a sign that hair products are clogging pores. Check product labels for “non-comedogenic” or “won’t clog pores,” wash pillowcases and hats, and give it 4 to 6 weeks after you stop the product.
What causes back and chest pimples?
These areas have some of the most oil glands on the body, and sweat, tight clothes and straps make it worse. The AAD suggests showering soon after sweating, loose clothes, and a benzoyl peroxide wash left on for 2 to 5 minutes. Itchy bumps that all look the same size can be “fungal acne,” which needs antifungal treatment.
Is acne face mapping accurate?
Not the organ version. No study we found links a zone of the face to an internal organ, and a dermatologist told fact-checkers face mapping “is not based on robust clinical trials.” Dermatologists do use location as a clue to products, friction, oil glands or hormones, which is what this map shows.
Can food cause acne in one spot?
No source we found ties a food to a zone of the face. Mayo Clinic says chocolate and greasy foods have little effect on acne, while carbohydrate-rich foods may make it worse, though more research is needed.
