One of the most frustrating things about acne is that the causes are genuinely varied,  and what’s driving your breakouts might be completely different from what’s driving your friend’s. Here’s a breakdown of the most common culprits.

Hormonal Fluctuations

Androgens like testosterone trigger excess sebum production. Peaks around your cycle, stress spikes, or hormonal shifts are the usual suspects.

Chronic Stress

Cortisol ramps up oil production and promotes inflammation,  two things acne thrives on. Stress-related breakouts tend to cluster on the jawline and chin.

Diet and Gut Health

High-glycemic foods and dairy have the strongest evidence for acne aggravation. The connection isn’t universal, but it’s real for a significant number of people.

Wrong Skincare Products

Comedogenic ingredients in moisturizers, foundations, and hair products can clog pores even when everything else in your routine is clean.

Genetics

If acne runs in your family, you’re more likely to produce more sebum and have more reactive skin. Genetics don’t determine your outcome ,  but they do set the playing field.

Sleep Deprivation

Poor sleep raises cortisol and slows skin cell repair. It’s rarely listed as a cause, but chronically tired skin is more prone to inflammation and slower to heal.

The best acne skincare routine is a consistent, simple one,  not the most elaborate one. More products mean more variables, more potential irritants, and more ways for your skin barrier to get overwhelmed. Here’s what a genuinely effective, clear skin routine looks like in practice.

Morning Routine

Gentle cleanser. Non-comedogenic moisturiser. Broad-spectrum SPF 30 or higher,  non-negotiable if you’re using any actives, because retinoids and acids make skin more photosensitive. That’s it for the morning. Three steps.

Evening Routine

Gentle cleanser. You’re active,  whether that’s a salicylic acid toner, a benzoyl peroxide treatment, or a tretinoin application. A light, non-comedogenic moisturiser to buffer the active and support your skin barrier. If you’re using tretinoin, start slow,  less is genuinely more, and the “purging” phase is real but temporary.
