Understanding Acne: What Causes Breakouts?
Acne vulgaris is the most common form of acne, encompassing both non-inflammatory (blackheads, whiteheads) and inflammatory lesions (papules, pustules, nodules).
Acne develops when excess oil (sebum), dead skin cells, and bacteria build up in your pores, leading to inflammation and breakouts. The primary culprits behind acne include:
Excess oil production: overactive sebaceous glands produce too much oil, which can clog pores and create the perfect environment for breakouts.
Clogged pores: when dead skin cells mix with oil and block pores, it traps bacteria and causes irritation.
Instead of shedding single cells, acne patients experience an overproduction of keratinocytes (skin cells), which leads to the accumulation of dead skin cells in hair follicles. This buildup combines with lipids, blocking the follicles and contributing to the formation of acne lesions.
Hyperkeratinization is a key factor in the development of both non-inflammatory and inflammatory acne.
Bacteria: Cutibacterium acnes (C. acnes), formerly known as Propionibacterium acnes (P. acnes), is commonly involved in acne. When trapped in clogged pores, they multiply and trigger inflammation.
Inflammation: the body’s immune response to clogged pores and bacteria often leads to redness, swelling, and painful breakouts.
But the story doesn’t end there—several underlying factors also influence acne:
Hormones: fluctuations in hormones, particularly during puberty, menstrual cycles, pregnancy, and even perimenopause, can trigger an increase in oil production. This makes hormonal imbalance one of the biggest contributors to acne.
Several hormones significantly contribute to acne development. Androgens like testosterone and dihydrotestosterone (DHT) stimulate sebum production and increase sebaceous gland activity, while estrogens can also influence acne formation. Insulin and insulin-like growth factor-1 (IGF-1) promote androgen production and sebaceous lipogenesis.
Growth hormone (GH) and glucocorticoids like cortisol exacerbate acne by increasing sebum, while corticotropin-releasing hormone (CRH) stimulates sebaceous lipogenesis. Prolactin and melanocortins also influence acne by affecting androgen levels and skin inflammation.
Genetics: if acne runs in your family, you’re more likely to experience breakouts, as genetics can determine how your skin reacts to different triggers.
Lifestyle factors: stress, diet, sleep habits, pollution and skincare routines all play a role in acne.
Pinpointing the exact cause of your acne can be challenging, which is why identifying the type of acne is key to finding the right treatment. Each type may require a different approach, from topical creams to hormonal therapies.
By understanding what's happening beneath the surface, you can choose treatments that effectively target your acne and restore balance to your skin. Let's break down the different types to help you get a clearer picture.
Non-Inflammatory Acne: Blackheads and Whiteheads
Non-inflammatory acne, like blackheads and whiteheads, forms without significant redness or swelling and results from clogged pores, not infection.
Comedones are acne lesions that occur when hair follicles become blocked with oil and dead skin cells. They can be open (blackheads) or closed (whiteheads) depending on whether the pore remains open to air or sealed.
Blackheads (Open Comedones)
Blackheads are small, dark spots that form when open pores are clogged with oil and dead skin. While they may look like dirt trapped in the pores, their dark color is actually caused by the oxidation of oil and dead skin cells when exposed to air.
They typically appear on the nose, chin, and forehead. Treatments include salicylic acid, retinoids, and gentle exfoliation. Avoid over-scrubbing, as it can worsen irritation and cause inflammation.
Chemical peels or microdermabrasion may help in more stubborn cases, especially for those struggling with frequent blackhead formation in the T-zone area.
Whiteheads (Closed Comedones)
Whiteheads are small, flesh-colored bumps that develop when a pore is fully blocked, trapping oil and bacteria beneath the skin. This full blockage creates a perfect environment for acne-causing bacteria to thrive, increasing the risk of further inflammation.
Whiteheads are most common on the cheeks, chin, and nose. They may feel firm to the touch and can be mistaken for tiny cysts or bumps.
Treatments like retinoids and glycolic acid help unclog pores and prevent new whiteheads from forming. Use non-comedogenic products (products specifically formulated to avoid clogging pores) to prevent further blockages.
Inflammatory Acne: Pimples, Papules, and Pustules
Inflammatory acne occurs when clogged pores become infected or irritated, triggering an immune response that leads to redness, swelling, and discomfort. Unlike non-inflammatory acne, it is usually more noticeable and may cause scarring if not treated properly.
Papules
Papules are small, red, inflamed bumps that lack visible pus and can be tender to the touch. They are commonly found on the face, neck, chest, and back, but they can appear anywhere on the body.
Papules are classified as Grade 2 acne and are described as small papules with erythema (redness).
Papules form when clogged pores become irritated from buildup of bacteria, oil, and dead skin cells. They can worsen into more severe acne if untreated.
Topical retinoids, benzoyl peroxide, or antimicrobial treatments help reduce inflammation and prevent pustules. Avoid picking papules to prevent scarring.
Pustules
Pustules are red, inflamed bumps with a visible white or yellow pus-filled center, making them resemble traditional "pimples." Classified as Grade 3 acne, they develop when papules become infected, and white blood cells collect at the surface.
Like papules, pustules are commonly found on the face, neck, chest, and back.
Picking pustules can worsen inflammation, increase infection risk, and lead to scarring. Treatment includes antimicrobials like benzoyl peroxide or salicylic acid, while oral antibiotics may be prescribed for more resistant cases. Let pustules heal naturally to avoid long-term damage.
Severe Acne: Nodules and Cystic Acne
Severe acne involves deep, painful lesions that can lead to long-term scarring if untreated. It includes nodules and cysts, which are harder to treat than mild or moderate acne.
Nodules
Nodules are large, hard, and painful lumps that develop deep beneath the skin's surface. They often appear on the face, jawline, neck, and upper body.
Nodules are classified as Grade 4 acne, which includes many pustules coalescing to form nodules and cysts (nodulocystic acne). Nodules often cause scarring and are more severe. They tend to be more painful and can last longer, often requiring more intensive treatment to prevent scarring.
Prescription medications like oral antibiotics or retinoids, and isotretinoin (Accutane) for severe cases to prevent scarring, are often recommended.
Cysts
Cysts are large, pus-filled, painful bumps that resemble boils and have a softer, more fluid feel compared to nodules. They are grouped with nodules under Grade 4 acne and are often considered part of nodulocystic acne. Cystic acne is commonly found on the face, neck, chest, back, and shoulders.
Cysts develop from deep infections and can cause significant scarring. Treatment usually includes oral antibiotics, hormonal therapy, or isotretinoin, with cortisone injections for quick relief. Avoid popping cysts to prevent scarring and infection.
Hormonal Acne: Recognizing the Patterns
Hormonal acne typically presents as deep, painful cysts or nodules concentrated around the jawline, chin, and lower face. These breakouts are often cyclical, flaring up around the same time each month, particularly before menstruation or when hormone levels abruptly rise or shift.
Hormonal fluctuations such as those during menstruation, pregnancy, or menopause, can trigger hormonal acne. Conditions like polycystic ovary syndrome (PCOS) also contribute by causing elevated androgen levels, which increase oil production and clog pores.
Adolescent acne also affects up to 90% of adolescents. Adolescent acne tends to be more common in males, while post-adolescent acne is more frequently seen in females.
Hormonal acne can be persistent, requiring targeted treatments that address the underlying hormonal imbalances. Options include oral contraceptives which help regulate hormone levels, or anti-androgen medications like spironolactone which reduce excess androgen activity.
Understanding these patterns helps in diagnosing hormonal acne and guiding treatment, especially when typical acne therapies are ineffective. Patients experiencing hormonal acne should also consider lifestyle modifications, including stress management and dietary changes, which can impact hormone levels.
Body Acne: Symptoms Beyond the Face
While facial acne is the most visible, body acne is common and can be just as frustrating. The back, chest, and shoulders are often affected, with a range of acne types appearing in these areas.
Body acne can also cause discomfort and lead to scarring if not properly managed.
Back Acne (Bacne)
Back acne typically involves a mix of blackheads, whiteheads, and inflamed pimples; outbreaks are triggered by sweating, tight clothing, and friction.
The skin on the back tends to be thicker and have more sebaceous (oil) glands than the chest and shoulders, making it prone to more widespread and potentially severe breakouts.
Treatment includes topical products like benzoyl peroxide or salicylic acid, with oral medications for severe cases. Reducing friction and showering after sweating helps prevent bacne.
Chest and Shoulder Acne
Acne on the chest and shoulders is similar to facial acne: both often feature papules and pustules. However, chest and shoulder acne can have more inflamed lesions due to the larger pores and thicker skin in these areas.
Chest and shoulder acne often features papules and pustules that are aggravated by sweat, friction, and hormonal imbalances. Hormonal fluctuations during puberty or pregnancy, along with exercise, can exacerbate breakouts.
Managing it involves reducing triggers with breathable fabrics and good hygiene, using topical treatments similar to those used for facial acne, and considering systemic treatment for persistent cases.
Clinicians should also consider hormonal factors when acne in these areas is persistent.
When to Seek Professional Help
If your acne becomes persistent, involves painful cysts or nodules, or results in severe scarring, it’s time to seek professional treatment. These more serious cases often don't respond well to over-the-counter solutions, and a dermatologist can help tailor a treatment plan to your needs.
Depending on the severity, treatment options may include topical medications like retinoids, oral antibiotics to reduce bacteria and inflammation, or hormonal treatments such as birth control or anti-androgens.
For more resistant cases, advanced procedures like cryotherapy or cortisone injections may reduce severe breakouts and minimize scars.
Preventing and Managing Acne
Managing acne starts with a solid skincare routine tailored to your specific type of acne. Choose non-comedogenic products that won't clog pores, and stick to a gentle cleansing and exfoliation routine to remove oil and dead skin cells without irritating the skin.
Lifestyle changes can also play a major role: managing stress, eating a balanced diet, staying hydrated, and practicing good hygiene can all help reduce breakouts.
Finally, consistency is key—results take time, and it’s important to be patient and stick with your treatment plan for long-term success.
Natural Support for Acne
- Dietary Adjustments: reduce consumption of high-glycemic foods and dairy products, as these can increase insulin levels and trigger breakouts.
- Probiotics: support gut health with probiotics to reduce inflammation and balance skin microbiome.
- Zinc Supplements: zinc can help reduce acne-related inflammation and promote skin healing.
- Omega-3 Fatty Acids: found in fish oil and some plant-based oils, omega-3s can reduce inflammatory acne by balancing inflammatory responses.
- Green Tea Extract: applying green tea extract may help lower sebum production and reduce inflammation.
- Stress Management: practice stress-reduction techniques like meditation or yoga, as stress can worsen acne through hormonal imbalances.
- Avoid Comedogenic Skincare: opt for non-comedogenic, natural skincare products to prevent clogged pores. Wash off all makeup every night.
Functional Medicine Perspective on Difficult-to-Treat Acne
Sometimes the underlying cause of acne is difficult to pinpoint. Targeted functional medicine questioning and testing can identify these issues and provide specific therapies.
Asking the patient about her or his diet, stress, skincare routine and personal care products is essential. A deep dive into toxin exposure may be considered.
Testing may also be indicated. Hormone cycle mapping is a test that can match hormone fluctuations to acne outbreaks, allowing for more targeted natural hormone support.
And because the skin mirrors gut health, patients struggling with acne and digestive symptoms may benefit from a thorough digestive health and microbiome assessment.
These tests, alongside diet and lifestyle adjustments, can provide life-changing support for patients who’ve not found relief with conventional therapies.
