Myths About Acne That Dermatologists Hear All the Time

This is one of the most enduring acne myths around. While some research suggests that high-glycemic diets (think white bread, sugary drinks) and large amounts of dairy may influence acne for certain individuals, the link to chocolate or greasy foods specifically is weak and inconsistent in clinical studies. Eating a burger doesn't deposit oil in your pores — sebum production is controlled internally by hormones, not by touching or consuming oily things.

Surface dirt doesn't cause acne — the process happens deep inside the follicle, where sebum and dead skin cells accumulate. Scrubbing aggressively or washing multiple times a day can disrupt the skin's natural protective barrier, increase dryness, and trigger more oil production as the skin tries to compensate. Most dermatologists recommend washing twice daily with a gentle, non-comedogenic cleanser and skipping the harsh scrubbing.

Spot treatments that rely heavily on drying agents — like certain high-concentration alcohol formulas — can cause peeling, redness, and irritation around the pimple without addressing the underlying cause. Ingredients like benzoyl peroxide or salicylic acid can be effective at appropriate concentrations, but the goal is treating the follicle, not desiccating the skin surface. A balanced, gentle approach supports faster, cleaner healing.

It's tempting, but squeezing a pimple often extends its lifespan rather than ending it. The pressure can rupture the follicle wall beneath the skin, spreading the inflammatory contents into surrounding tissue and creating a larger, more painful lesion. It also introduces bacteria from your hands into an already-inflamed area. Dermatologists who do drain pimples use sterile instruments and specific techniques — what happens at home is rarely comparable.

Hormonal fluctuations, stress, certain medications, and even some skincare products can trigger acne at any age. Studies suggest adult acne affects a significant portion of women in their 20s and 30s, and it's not unusual in men either. Adult acne often presents differently than teenage acne — frequently appearing along the jawline, chin, and neck — and may require different treatment strategies. Dismissing it as something you should have outgrown can delay effective care.

This myth likely comes from early, heavier sunscreen formulas that weren't ideal for oily skin. Today, there's a wide range of lightweight, oil-free, and non-comedogenic (won't clog pores) options. Sun protection is especially important for people with acne because UV exposure can worsen post-inflammatory hyperpigmentation — the dark marks left after a pimple heals. Skipping SPF to avoid breakouts is a trade-off that generally doesn't pay off.
