Is Back Acne Really Folliculitis? Editor's Treatment Trial Reveals All! 8 Causes & 5 Solutions You Should Know

There’s a common belief that back acne reflects poor lung health, and that people with excess heat and dampness in their lungs are more likely to develop acne on their backs, especially recurring outbreaks. From a Western medical perspective, back acne could actually be folliculitis. Acne commonly appears in areas with active sebaceous glands such as the cheeks and back, while folliculitis tends to occur in areas with fewer oil glands like the scalp and nape. So, is back acne actually folliculitis or just typical acne? Read on for a self-assessment!

Is Back Acne Folliculitis?

A dermatologist explains that acne can form anywhere hair grows. But what’s the difference between acne and folliculitis? Acne typically occurs in oil-rich areas like the face and back, while folliculitis is more common in less oily zones like the scalp and back of the neck. Folliculitis is mainly caused by bacteria, especially Staphylococcus aureus. Treatments for acne and folliculitis differ, and extra care should be taken with the pus in folliculitis to avoid spreading infection to other skin areas or even other people. If you're unsure whether your back acne is folliculitis or regular acne, it’s best to consult a dermatologist instead of self-treating and risking complications.

Does The Location Of Back Acne Reveal Internal Issues?

Can acne location indicate health problems? It's often said that back acne is linked to poor lung health or "lung heat," leading to repeated breakouts and persistent acne scars. According to Traditional Chinese Medicine (TCM), different parts of the back correspond to different internal organs, so it's not as simple as blaming "lung heat."

• Shoulders & upper back: Commonly due to lung heat
• Middle back: Often linked to damp-heat in the stomach and intestines
• Lower back: Usually related to damp-heat in the liver, gallbladder, and kidneys, often triggered by stress or excessive alcohol

Is it lung heat or kidney heat?

According to TCM, back acne is most often seen on the upper back, followed by the mid-to-lower back. Full-back breakouts are rare. The back is considered a concentration point for yang energy, with the Governing Vessel and Bladder Meridian running through it. Acne on the upper back usually stems from lung heat, while lower back acne points to liver-gallbladder-kidney damp-heat.

Is it a deficiency or excess syndrome?

To effectively treat back acne, you need to identify whether it’s a deficiency or excess pattern:

Excess patterns may include:

○ Wind-heat in the lung meridian
○ Damp-heat in the intestines
○ Phlegm-damp stagnation (These require a full TCM diagnosis via observation, listening, questioning, and pulse-taking.)

Common back acne patterns:

• Heat-dominant type: Red, swollen acne; red tongue
• Damp-dominant type: Loose stools, fatigue, thick tongue coating
• Yin deficiency with internal heat: Dry mouth, warm palms/soles, night sweats
• Spleen and stomach deficiency: Cold intolerance, poor appetite, loose stools

Western Medicine View: What Causes Back Acne?

Dermatologists note that the back has a high concentration of sebaceous glands. Back acne is common in teenagers and adults in their 30s–40s. For teens, increased oil production during puberty clogs hair follicles. For working adults, stress, poor sleep, and hormonal imbalances can overstimulate oil glands. Women may also develop back acne due to hormonal changes before menstruation. Other common triggers include:

• Puberty
• High stress
• Lack of sleep/rest
• Hormonal fluctuations
• Staying up late
• Poor diet
• Hot and humid spring/summer weather

Common Causes Of Back Acne

Cause 1: Inadequate rinsing during showers

Back acne is often due to poor hygiene—not from skipping body wash, but from not fully rinsing off shampoo or conditioner. Leftover product can clog pores and cause breakouts.

Cause 2: Using loofahs or back brushes

Many use loofahs or long-handled brushes to clean hard-to-reach spots. While convenient, dermatologists advise against this as these tools are hard to disinfect and can harbor bacteria, especially in humid bathrooms. Washing with your hands is actually safer and more hygienic.

Cause 3: Dressing before your body is dry

Putting on clothes while your skin is still damp traps moisture and chemical residues (from detergents, fabric softeners, etc.) against your skin—creating a perfect breeding ground for bacteria, especially in tight-fitting clothes.

Cause 4: Wearing tight clothes

Skin needs to breathe. Tight or non-breathable clothing traps sweat and oil, especially during hot weather or workouts, increasing your risk of back acne.

Cause 5: Dirty bedding

Pillowcases, sheets, and pajamas are in constant contact with your skin and can harbor oil, dead skin cells, and bacteria—even if they look clean. Regular washing and disinfection are key to preventing back acne.

Cause 6: Stress and lack of sleep

Back acne isn't just for teens—many busy adults also break out suddenly. Stress, poor sleep, and hormonal imbalances can disrupt the immune system and increase oil production, leading to persistent flare-ups.

Cause 7: Unbalanced diet

From a TCM standpoint, back acne is caused by internal "heat." Spicy, salty, or sugary diets can cause heat and dampness in the body, which overstimulates oil glands and clogs pores.

Cause 8: Seasonal and temperature changes

Hong Kong's hot and humid spring/summer climate can worsen damp-heat body conditions. High humidity and heavy sweating create a bacteria-friendly environment—especially if sweat isn’t cleaned off quickly. Wet clothes clinging to your back turn it into a breeding ground for breakouts.

Symptoms Of Back Acne

Common areas affected

Mostly the upper back, then mid-to-lower back. Full-back breakouts are rare and often due to bacterial/fungal infections or immune issues.

Appearance

Back acne usually presents as red and swollen pimples. In severe inflammation, they may feel hot or painful. In TCM, the bright red color suggests heat buildup (a "yang" condition), while darker purplish ones often indicate stress-related acne and are more common in middle-aged individuals.

Pus heads

Most back acne doesn’t form pus heads at first. These may appear after 2–3 days, and once the pus drains, the pimples typically subside—though they may leave marks behind.

Other common symptoms:

• Mood swings
• Irritability
• Dry mouth
• Bitter taste in the mouth
• Bloating
• Thick tongue coating
Women may also notice bright red menstrual blood with heavier or irregular flow.

Back Acne Treatment — Traditional Chinese Medicine (TCM)

How does Traditional Chinese Medicine treat back acne? TCM practitioners don't just look at the location of the acne on the back, but also examine the color, presence of pus, and any other discomforts in the body to determine whether the condition is due to "deficient heat" (虛熱 in Chinese) or "damp heat" (濕熱).

Back acne with excess syndrome (實證): The acne is visibly red, swollen, and painful, with pus developing quickly.

Back acne with deficiency syndrome (虛證): The pain is mild and lingering, with pus slow to form — often indicating a deficiency or a mixed deficiency-excess syndrome.

If the back acne is classified as yin deficiency with blood heat (陰虛血熱型), TCM usually prescribes herbs with sweet and cooling properties to nourish yin and clear internal heat. A common formula is Liu Wei Di Huang Wan, often enhanced with ingredients like gardenia (梔子) and anemarrhena (知母) to target internal heat. In addition to oral medication, external applications may also be used. Herbs like forsythia (連翹), natural indigo (青黛), and borneol (冰片) have anti-inflammatory and swelling-reducing properties and are safe for topical use without concerns of over-cooling the body.

Beyond herbal remedies, some TCM practitioners use acupuncture and cupping therapy to treat back acne. Acupuncture helps clear blocked meridians and promotes detoxification, while microneedling combined with cupping draws out stagnated blood from acupoints on the back, enhancing microcirculation effectively.

Back Acne Treatment — TCM Diet and External Applications

Back Acne Remedy 1: Red Bean and Coix Seed Porridge

This porridge helps remove dampness, strengthen the spleen and stomach, and boost qi and blood — especially beneficial for women.

Ingredients: Coix seed (Job's tears), fox nut (芡實), red beans (赤小豆), and a bit of rock sugar. Adjust the quantity based on serving size.

Method: Soak red and adzuki beans in cold water for an hour. Lightly toast the coix seeds until slightly yellow. Boil all ingredients for 2 hours. This porridge helps improve back acne, boosts blood circulation, and clears meridians.

Back Acne Remedy 2: Mulberry Leaf, Chrysanthemum, and Green Bean Soup

Mulberry leaves, chrysanthemum, and green beans help clear heat. Combined with coix seeds, which remove dampness, this drink clears lung heat — ideal for back acne sufferers. Bundle mulberry leaves and chrysanthemum in a tea bag. Add raw coix seeds and green beans to boiling water and cook for 30 minutes. Sweeten with rock sugar if desired. Note: Not suitable for individuals with cold constitutions or diarrhea issues.

DIY Herbal Acne Mask

Ingredients: Raw coix seeds, green beans, honeysuckle, coptis root (黃連), and rhubarb (大黃).

If your back acne is inflamed and painful, you can make a DIY herbal paste to soothe and reduce inflammation. Grind all ingredients into powder, add a small amount of water to form a paste, apply to affected areas, and gently massage in circular motions to help absorption. Rinse off after 15 minutes — this effectively soothes burning and inflammation.

Since every body constitution varies (cold vs. hot, excess vs. deficiency), it's recommended to consult a TCM practitioner before consuming any herbal remedies.

Back Acne Treatment — Western Medicine

How do dermatologists treat back acne? Depending on the symptoms, doctors may prescribe different medications. Typically, treatment starts with topical medications such as antibacterial ointments, antibiotic creams, or retinoid (AHA) creams.

For more severe cases, doctors may recommend salicylic acid chemical peels to unclog pores and accelerate healing. Medical aesthetic treatments like laser therapy may also be used to suppress sebaceous gland activity, reduce oil production, and lighten back acne scars.

If topical treatments are ineffective, oral antibiotics or oral retinoids (e.g., isotretinoin) may be prescribed to suppress acne-causing bacteria and shrink sebaceous glands, targeting the root cause of back acne.

How To Prevent Back Acne?

Prevention Tip 1: Use Acidic Ingredients to Unclog Pores

Incomplete rinsing during showers, chemical residue on the back, and thickened keratin layers are key causes of back acne. However, dermatologists advise against using bath balls or sponges, as they may increase bacterial infections. For exfoliation, use body lotions or masks containing acids like glycolic acid or salicylic acid — great friends to acne-prone backs.

Prevention Tip 2: Wear Loose Clothing

Tight, non-breathable clothing creates friction and heat, triggering back acne and reopening scabbed wounds. Wear cotton, loose, and breathable clothing to minimize skin friction and reduce sweat and oil buildup. The same goes for workout attire — avoid tight tanks.

Prevention Tip 3: Maintain a Balanced Diet

Don’t underestimate how your diet affects back acne. It’s closely linked to bathing habits, clothing, diet, and sleep. Spicy, salty, and sugary foods can elevate androgen levels, increasing sebum production and clogging pores. Milk, dairy products, high-sugar foods, and those with a high glycemic index have also been shown to promote acne.

Prevention Tip 4: Shower After Exercise

Back acne sufferers must clean their backs thoroughly, especially after sweating. Wiping with a towel helps a bit, but sweat can still leave a residue on your skin. If possible, shower immediately and change into clean clothes. When towel drying, pat gently to avoid irritating your acne.

Prevention Tip 5: Be Mindful of Bath Products

Overly moisturizing or overly cleansing shower gels and shampoos can cause back acne. Excess oil clogs pores, while strong cleansers strip the skin's natural barrier, prompting more oil production — worsening acne. Choose simple, gentle formulas for shampoo and body wash. For conditioner, switch to leave-in conditioners or hair oils/serums.
