“Oh my gosh, don't you ever get acne?” While people with oily skin envy those with dry skin or skin that never breaks out, those people have plenty of troubles you don't know about! Even our editor has had a pimple on the belly button. So why does acne show up elsewhere instead of on the face? The most common spots are the chest and back, and one careless pick can make them bleed or leave scars. This article rounds up all of these concerns in one place: why does acne appear in odd places, what can improve it, and what should you do about the acne scars it leaves? Let's find out together.
Why Acne Appears on the Chest and Back
The skin's “sebaceous glands” are widely distributed across the whole body, and key areas include the scalp, face, chest, back, upper arms, shoulders, and buttocks, so if the sebaceous glands secrete too much oil or keratin turnover is abnormal, pores easily become clogged and form acne.
Cause of Back Acne: Excess Sebum Production
Back skin is just like facial skin: when the sebaceous glands secrete too much oil, the skin easily becomes inflamed, leading to acne. Especially in summer, when the climate is humid and hot, sebum secretion is also more vigorous than in winter, so back acne is more likely to appear.
Cause of Back Acne: Abnormal Keratinization and Clogged Pores
In a healthy state, human skin renews itself every day, but acne-prone skin has abnormal turnover, which easily leaves sebum that has not been fully shed to build up. As a result, excess sebum secretion builds up and forms comedones, and when too many comedones become infected, they turn into acne.
Cause of Back Acne: Inflammation Around the Hair Follicles
Back skin is covered by clothing for long periods in a hot, stuffy environment, so sebum secretion is more pronounced. Therefore, when there is too much oil and grime on the back skin, clogging pores and triggering an inflammatory reaction, acne is even more likely to appear.
Cause of Back Acne: Acne Bacteria Infection
A closed pore environment easily breeds acne bacteria (Cutibacterium acnes). Once infected, it can develop further into pustular acne.
In summary, the causes of chest and back acne are all influenced by genes, hormones, and psychological stress and other factors. Besides causing large patches of acne, they may also turn into acne scars and pigmentation.
Back Acne Everywhere? Understanding Causes and Care Methods: A Complete Back Care Guide
How Can You Improve It?
(1) Improve your lifestyle habits: avoid staying up late and heavy stress, and try to stay relaxed
(2) Adjust your eating habits: avoid spicy foods and sugary drinks, and avoid refined starches (milk and cheese should also be avoided as much as possible)
(3) Studies show that whey protein may affect hormones and make them unstable, leading to comedones and acne
P.S. People with severe acne must see a doctor for diagnosis and take or apply medication as the doctor instructs.
How to Choose Body Wash for Back Acne
If you struggle with back or chest acne, we recommend choosing a mildly acidic body wash (close to skin pH) that is soap-free. Alkaline soap or body wash actually dries out the skin and does not help improve acne.
In addition, we remind you that over-exfoliating is not recommended while you have back acne. It not only fails to treat the acne but may also make the skin more fragile!
Common Misconceptions About Back Acne
(1) Over-Cleansing
Never over-cleanse!! The purpose of cleansing is to wash away surface oil and dirt, and the right standard is that the skin does not feel dry. Washing too clean actually makes skin fragile.
(2) Does Sunscreen Cause Back Acne?
Sunscreen basically has little to do with breakouts. To have a clean, beautiful back, you must protect it from the sun, since skipping sunscreen only makes acne scars worse! As long as you cleanse well in the shower, sunscreen will not cause acne.
(3) Wearing Overly Close-Fitting or Tight Clothing
Wearing tight clothing for long periods easily causes dirt and bacteria on the skin to rub repeatedly against clothing fibers, which irritates the skin and may lead to folliculitis or acne.
(4) Is Applying Sunscreen Enough?
Studies show that UV rays have a significant effect on skin aging and on worsening acne. However, applying sunscreen that is too thick may burden the skin, and combined with Taiwan's hot, humid climate, it easily causes sweat and bacteria to overgrow, leading to back acne. Therefore, choosing sunscreen products carefully and finding one suited to your skin and your local climate is also very important!
(5) What Does Drinking Water Have to Do With Acne Scars?
Many people wonder: aren't drinking water and getting acne two separate things? In fact, water is an essential element for keeping the body functioning. For normal metabolism, you need to get enough water every day, which not only promotes metabolism but also improves skin hydration and makes your skin look even better!! (This is also why many people say: “I got prettier by drinking water!”)
What to Do About Acne Scars?
Acne scars and pigmentation left by acne can be faded and brightened with AHA skincare products. However, when using acid products, take special care that the concentration is not too high. We suggest testing on a small patch of skin first, and applying to the whole back only after confirming it is not overly irritating.
Once your skin condition is stable, you can also choose a faster way to restore it, the well-known “picosecond laser”. Picosecond laser is well known for “improving acne scars and dull skin.” The treatment frequency depends on your situation, and we recommend one session every one to two months; after completing the recommended course, your skin can return to its natural state.

How to Prevent Back Acne
(1) Exfoliate Regularly and Master the Tips:
The early stage of back acne is abnormal keratin turnover in the skin, which easily clogs pores and causes pimples and comedones on the back. The key to improving acne is regularly using gentle exfoliating products containing mandelic acid, AHA, or enzymes.
You can also choose the common “mandelic acid peel”, in which a professional aesthetician helps care for your skin, which not only improves the problem but also maintains the skin! Mandelic acid can help metabolize old dead skin cells, unclog pores, and prevent comedones, gently expelling “deep comedones and excess keratin”, and it has the effect of “preventing skin inflammation and unclogging pores.” It effectively reduces the buildup of old dead skin cells and clears dirt from pores without over-irritating the skin, which helps avoid back acne and back comedones.
In addition, HydraFacial can also solve this problem! Most people only know HydraFacial for the face, but in fact HydraFacial also has a body-specific tip that clears old dead skin and comedones from the skin surface without harming the protective keratin layer. Compared with ordinary exfoliating scrubs on the market, the water vortex cleansing method is gentler and more skin-friendly.
While cleansing, it can also instantly infuse beauty serums such as small-molecule hyaluronic acid and antioxidants, making cleansing and care seamless and complete in one step, instantly boosting the skin's hydration and protection!

(2) Don't Irritate or Squeeze Back Skin or Pimples
To keep a beautiful back and avoid dark pigmentation, the first step in caring for back skin is “don't irritate, squeeze, or pick at” your back skin, because squeezing or picking open pimples makes them worse and can lead to skin infection or scarring.
