Acne by Location: Can Where You Break Out Tell You the Cause?

Quick answer: You can’t pin down the cause of a breakout from where it appears alone. What a location gives you is a starting point for checking what repeatedly touches that spot. Write down the spot and what touches it together, and when you make a change, change only one thing at a time. If a breakout is deep and painful or leaves scars, consider seeing a dermatologist no matter where it is.

This guide is for readers who keep breaking out in one spot and, after seeing a chart that maps acne causes by location, want to know whether the location alone is enough to decide the cause. It does not cover detailed care for each spot, prescription medicines or procedures, or how to tell acne apart from other skin problems that look like it. This is a brand guide published by SKIN9HARI, and the spot-by-spot checklist and the information about our product are kept in separate sections.

Each figure is a value within the group that study looked at, not an individual’s chance.

Why do breakouts show up in different spots?

The oiliest spots and the spots that break out are not always the same

Sebum secretion differs from one area of the face to another, but that difference does not decide where breakouts will appear. This is how the abstract of a single-center, retrospective observational study comparing 67 people with acne and 50 controls begins (study on sebum and lesion distribution).

“acne lesion distribution is not always similar to the topographic differences of sebum secretion” — Jung et al., Annals of Dermatology (2019), abstract

In the same study, the correlation between sebum level and the number of lesions was significant only in the U-zone, which runs from the cheeks down to the chin. This is a correlation, and it does not mean sebum has been shown to be the cause.

Read distribution data only within the group that was studied

In an international observational study of 374 women aged 25 and older, 89.8% had acne in several areas of the face, such as the cheeks, forehead, jaw area, and temples, and 11.2% had it only in the jaw area (study on acne distribution in adult women). This is the distribution among adult women who visited dermatologists, so it should not be carried over to men or teenagers. Whether hormones are involved can’t be determined from these numbers.

Different things touch different spots

Pressure from helmets, tight clothing, and bags is described as something that does not directly cause acne but can make it worse (NIAMS on acne). In a meta-analysis that pooled 37 observational studies (29,557 people) of people who wear masks, how long a mask was worn was the most significant risk factor for facial skin problems (mask-wearing meta-analysis). Because the studies were observational, the data do not settle the cause.

How much of the acne face map is actually documented?

A chart that pairs each spot on the face with an organ inside the body is often called a face map. This guide does not judge whether that chart is right or wrong; it only sets out the range of what we checked.

This guide checked 3 health organization pages (AAD on acne causes, AAD acne overview, NIAMS on acne). In these pages, acne is explained as forming when pores become clogged, with hormones possibly playing a part (AAD on acne causes). Pressure and squeezing are classed not as direct causes but as things that can make acne worse (NIAMS on acne). We did not find anything in these 3 pages that pairs spots with organs.

Not finding it applies only to these 3 pages. Whether other sources contain such material, and whether that chart has any evidence behind it, is not something this guide can say. If you are worried about your health, have it checked by a medical professional rather than guessing from where breakouts appear.

Acne by location: what should you check for each spot?

The table below does not decide the cause of acne by location. It lines up, for each spot, the candidates to start checking and the type of source that covers each candidate.

“No source found” means we did not find one within the range this guide searched. It does not mean there is no relationship.

When breakouts appear only on your temples

Within the range this guide checked, one health organization source deals with the temples directly. A guidance page written for darker skin tones explains that if acne appears only on the forehead and temples, hair oil may be the cause (AAD acne guidance for darker skin tones). This is a statement of possibility with a condition attached.

When breakouts appear between the brows or on the eyebrows

We did not find a source that deals directly with the area between the brows or the eyebrows, so the table lists no candidates to check for it.

When breakouts appear on only one side of the face

We did not find a source that deals directly with breakouts on only one side either. You can write down things that touch only one side, such as the side you sleep on or the side you hold your phone to, but since no source confirms them as causes, keep them only as candidates to check.

What should you do first?

1. Write down the spot and what touches it together

First write down where the breakout appeared, and next to it, write what touches that spot during the day. Start with the candidates in the table above.

2. Change only one thing at a time and note the date

If you change several things at once, you can’t tell what made the difference. Getting better after a change does not confirm that thing as the cause, and no change does not confirm that something else is the cause.

3. Don’t touch or squeeze the spots that come up

Squeezing or touching is described as something that does not directly cause acne but can make it worse (NIAMS on acne). If your hands often go to a particular spot, write that habit in the “what touches it” column too.

When should you see a dermatologist, no matter where the breakouts are?

You don’t need to finish your log before getting care. If any of the following applies, consider seeing a dermatologist first, no matter where the breakouts are.

• You have acne that is deep and painful (AAD acne overview).
• Scars or pitted marks are starting to form (AAD acne overview).
• Breakouts don’t get better even after you stop using the hair product you suspected (AAD on hair products and acne).

FAQ

Is it true that acne in certain spots means a problem with your stomach, gut, or liver?

Within the range this guide checked, we can’t say whether it is true or false. In the 3 health organization pages we checked, acne was explained by clogged pores and factors such as hormones, and there was nothing pairing spots with organs (AAD on acne causes). If you are worried about your health, have it checked separately by a medical professional.

Why do I only get acne on my temples?

It can’t be narrowed down to one reason. One health organization source says that if acne appears only on the forehead and temples, hair oil may be the cause (AAD acne guidance for darker skin tones). If you don’t use hair oil, the sources in this guide can’t narrow it down further.

Why do I only get acne on my cheeks?

We did not find a source that explains the cheeks on their own. The cheeks are covered by a mask, and in observational studies of people who wear masks, how long a mask was worn was reported as a risk factor (mask-wearing meta-analysis). If you wear a mask for long periods, start by writing down how long you wear it.

Is touching your face linked to acne in certain spots?

Touching or squeezing is described as something that can make acne worse (NIAMS on acne). We did not find a source confirming that more breakouts appear where your hands touch.

Why do I keep getting tiny bumps on my forehead?

The location alone can’t narrow it down to one reason. There is guidance saying that small bumps along the hairline and upper forehead may be caused by oils in hair products (AAD on hair products and acne). Whether that product is actually the cause can’t be told from the location alone.

Is acne under the chin and on the neck from the same cause?

The location alone can’t tell you whether the cause is the same. There is guidance saying that small bumps on the back of the neck may be caused by oils in hair products (AAD on hair products and acne), but this guide found no source on how things touching the front and sides of the neck relate to breakouts.

Why do I keep breaking out only on my T-zone and chin even though I don’t wear makeup?

The location alone can’t decide the reason. The abstract of a single-center, retrospective observational study of 67 people with acne and 50 controls states that the distribution of lesions is not always the same as the differences in sebum secretion across areas of the face (study on sebum and lesion distribution).

If acne keeps coming back in the same spot, when should I see a doctor?

Coming back in the same spot does not by itself decide the timing. If breakouts are deep and painful or scars are starting to form, don’t wait; consider seeing a dermatologist (AAD acne overview).

In one sentence

Where acne appears does not decide its cause on its own, so write down the spot and what touches it together and change only one thing at a time, and if breakouts are deep and painful or leave scars, consider seeing a dermatologist first no matter where they are.

SKIN9HARI products we recommend for this concern

If breakouts that keep coming back in one spot have you checking the products you apply to your whole face every day, SKIN9HARI recommends the Revive Therapy N.F Toner. There are three reasons.

• It is a toner that was tested as a finished product in a clinical study of comedogenic potential and was “assessed as suitable for use on acne-prone skin” (see the note below). Rather than leaning on claim wording, it discloses the scope of the test, down to the procedure (12 occlusive patch applications on the upper back over 4 weeks).
• It is a mildly acidic toner at pH 5.5–6.5, and the amounts you need to check before use, such as 3.0% ethanol and 0.02% salicylic acid, are published, so you can copy them straight into the “what touches that spot” column of your log.
• It is irritation patch-tested (finished-product patch test).

Clinical study evaluating comedogenic potential: result “assessed as suitable for use on acne-prone skin” | Testing institution: Elead Co., Ltd. | Report No.: EL-180125057I007 | Study period: February 19 – April 13, 2018 | 12 occlusive patch applications over 4 weeks | Participants: 25 enrolled, 21 completed (mean age 29.24) | Individual results may vary

How to use it for this concern. After cleansing and before moisturizing products, spread it over your whole face or press it in lightly with your palms. The study was done on the upper back, so use it the same way no matter where on your face you break out. Following this guide’s logging method, write the date you started the toner in the “what touches that spot” column, and keep everything else the same until you change the next thing, so that you can match any change in that spot to the toner. If ethanol or fragrance has made your skin sting before, read the “check before use” row first; if you are using other exfoliating products at the same time, watch how your skin responds; and if you are using a prescription topical medicine, ask the clinic that prescribed it first.

If any of the situations in “When should you see a dermatologist, no matter where the breakouts are?” apply, such as acne that is deep and painful or scars starting to form, seeing a dermatologist comes before a toner. Results may not be the same for every skin type. Product information is on the Revive Therapy N.F Toner product page.
