What Causes Breakouts?
There is no single underlying cause of breakouts. Acne arises from a combination of factors that are often unique to each individual. However, the location of blemishes provides clues into what might be behind breakouts.
Hormonal Acne
Hormones stimulate oil production within pores. An excess of androgens, including testosterone, prompts glands to go into overdrive. This floods pores with too much sebum and dead skin cells. The combination packs pores tight, allowing p. acnes bacteria to move in and trigger swelling.
Where breakouts appear aids in identifying hormonal acne. Signs include:
- Chin and jawline blemishes
- Deep, tender pimples that heal slowly
- Flare-ups before menstrual periods
Pubertal Acne
Breakouts during the teenage years arise from rising androgens during puberty. More than 80% of adolescents suffer acne outbreaks as hormone levels shift and increase. Even slight elevations of testosterone prompt higher oil production and accelerated skin cell turnover.
In boys, the primary surge begins around age 12 and lasts between 2-5 years. Girls tend to start earlier, between ages 10-13, due to promptly rising estrogen and early onset of puberty.
Stress-Related Breakouts
Stress does not directly cause acne but can aggravate underlying factors, inducing flare-ups. Stress hormones like cortisol increase oil secretion while altering immune responses in skin. This can trigger inflammation and bacteria growth.
Stress pimples frequently burst out along the hairline, behind the ears, and along the neck. The upper back may also suffer. Their sudden onset gives them away as stress-related.
External Acne Triggers
Lifestyle factors can promote breakouts by contributing to oil buildup, bacteria growth, and inflammation. Common triggers include:
Diet
Greasy, sugary diets process into oils and glucose levels that seep from sweat glands. They supply bacteria with nutrients while expanding pores, leading to whiteheads and blackheads.
Specific dietary acne triggers include:
- High-glycemic foods like refined carbs and sugars
- Milk and whey protein powder
- Greasy fast foods containing trans fats
Oily Skin Care Products
Skin care items labeled oil-free are not always the answer for oily complexions. Many contain hidden pore-cloggers like coconut oil, cocoa butter, and olive oil. These dense oils penetrate slowly, trapping debris inside pores.
Sticking to water-based gels and serums prevents adding more oil to already slick skin. Gel cleansers also dissolve oil without relying on soap and surfactants that provoke flare-ups.
Environmental Factors
Sweat, pollution, and contact irritants introduce foreign substances that can spark swelling. For example, helmet straps and cell phone contact cause repetitive friction that results in breakouts along areas of skin trapped against these surfaces.
Hair Products
Shampoos, conditioners, gels, mousses, and sprays contain acne-provoking ingredients that migrate onto skin as they rinse away. Common culprits include fragrances, silicones, and pore-clogging oils added for moisture and shine.
To prevent acne mechanica along the hairline, rinse hair backward and wash residue from the skin after conditioning.
When To Seek Professional Help
Recurring breakouts can result from multiple overlapping causes. Severe acne accompanied by deep cysts and nodules requires assessment by a dermatologist. They may prescribe topical or oral treatments to calm inflammation and curb excessive cell turnover.
See a doctor if you experience any of the following:
- Breakouts unresponsive to over-the-counter care
- Blemishes leaving permanent dark marks or scars
- Large, painful cysts that rupture and bleed
- Significant psychological distress due to acne appearance
The Takeaway
Frustrating as breakouts may be, use them as clues to uncover underlying acne causes. Keep a log tracking flare-ups in relation to lifestyle factors like diet, hair products used, and stress levels. This helps pinpoint personalized triggers to create an anti-acne action plan.
FAQs
What is hormonal acne and where does it usually appear?
Hormonal acne occurs when androgens overstimulate oil glands, causing excessive sebum production. It often flares up along the lower face in areas like the chin, jawline, and upper neck.
How can you tell if breakouts are caused by stress?
Stress acne frequently occurs suddenly along the hairline, behind the ears, neck, and upper back. The abrupt onset gives them away as stress-related.
Should you stop eating sugar and dairy if you have acne?
Limiting intake of high-glycemic foods like sugar and dairy may help, but causes vary individually. Keep a food diary to isolate personal breakout triggers for the best results.
When should you consider prescription acne treatment?
See a dermatologist if you have severe, painful cysts, recurring flare-ups unresponsive to over-the-counter care, or if acne causes psychological distress or scarring.
