Acne is one of the most common skin conditions worldwide, affecting teenagers and adults alike. It occurs when hair follicles become clogged with oil, dead skin cells, and bacteria, leading to whiteheads, blackheads, pimples, or deeper cysts and nodules. Breakouts can appear on the face, chest, back, and shoulders and may fluctuate with hormones, diet, stress, and skincare habits. Understanding the underlying causes and evidence-based approaches to care can help you manage and reduce acne over time.
Why acne happens and what drives breakouts
Acne starts deep within hair follicles when excess sebum (oil) and dead skin cells mix and block pores. This creates a fertile environment for acne-causing bacteria such as Cutibacterium acnes to multiply, resulting in inflammation and visible breakouts. Hormonal fluctuations, especially during puberty, menstrual cycles, or hormonal disorders like PCOS, can increase oil production and make acne worse. Stress and poor sleep also influence hormone balance and inflammatory responses, contributing to flare-ups.
Diet, inflammation, and skin health
Dietary factors can influence acne by affecting inflammation and hormonal signaling. Diets high in high-glycemic foods (like white bread, sugary snacks, and processed carbs) can spike insulin and other hormones that stimulate sebum production, increasing the risk of breakouts. Cutting back on high-glycemic foods and sugary beverages may help reduce acne severity. Some evidence also links dairy products, especially milk and whey protein, with increased acne, possibly due to hormone-related effects.
Proven acne treatments and skincare steps
Topical treatments for acne
Retinoids, benzoyl peroxide, and other topical products help unclog pores, reduce inflammation, and support skin healing.
Prescription and medical treatments
Oral antibiotics, hormonal therapy, or isotretinoin may be recommended for moderate to severe acne.
Clinical procedures
Chemical peels, laser therapy, and professional extractions can address persistent acne or post-acne scarring.

Natural remedies
Some people use apple cider vinegar as a natural toner to help balance skin pH and reduce bacteria. Aloe vera gel is a gentle, natural remedy for acne-prone skin. It has antibacterial and anti-inflammatory properties that can help reduce redness, calm irritation, and promote healing of blemishes.
Lifestyle, prevention, and long-term skin health
While diet is not a single cure, certain eating patterns may support clearer skin over time. Focusing on low-glycemic, nutrient-dense foods, such as leafy greens, whole grains, lean proteins, and omega-3 rich fish, may help reduce systemic inflammation and stabilize blood sugar, both of which can influence sebum production and flare-ups. Hydration is also essential; water helps support skin elasticity, detoxification, and balanced oil production.
Healthy habits and trigger management
Good habits can help prevent breakouts and promote healing:
- Stay hydrated to support skin barrier function.
- Avoid touching or picking acne-prone areas to reduce irritation.
- Shower after sweating to remove excess oil and bacteria.
- Identify and reduce triggers such as stress, poor sleep, and friction from helmets or phone pressure on the face.
Consistent self-care and awareness of your triggers help you build a routine that minimizes breakouts over time.
