Acne Treatment And Prevention: What Actually Works

Acne is common and treatable, but it is not caused by “dirty skin” and usually does not improve by scrubbing harder. Effective care focuses on keeping pores from clogging, reducing inflammation, controlling acne-causing bacteria, and protecting the skin barrier.

Start with a gentle routine

Wash gently up to twice daily and after heavy sweating.
Use non-comedogenic moisturizer if acne treatments make skin dry.
Use broad-spectrum SPF 30 or higher when outdoors.
Avoid harsh scrubs, picking, squeezing, and repeatedly changing products.

Over-the-counter ingredients with evidence

Benzoyl peroxide

Benzoyl peroxide helps reduce acne-causing bacteria and inflammatory pimples. It can cause dryness or irritation and may bleach towels or clothing. Starting with a lower strength can improve tolerability.

Salicylic acid

Salicylic acid helps unclog pores and can be useful for blackheads and whiteheads. More exfoliation is not always better; irritation can worsen the appearance of acne-prone skin.

Adapalene

Adapalene is a topical retinoid available without prescription in the United States. It helps keep pores clear and can treat acne over time. Retinoids can initially cause dryness and irritation, so introduce them gradually and moisturize. Topical retinoids should not be used during pregnancy unless specifically directed by an appropriate clinician.

Give treatment time

Acne treatment usually takes weeks rather than days. Switching products every few days can increase irritation before an ingredient has had a fair trial. Use products as directed and add one active ingredient at a time.

Diet and acne

Diet is not the sole cause of acne. Research suggests that high-glycemic dietary patterns may worsen acne in some people, and dairy has been studied as a possible contributor in some populations, but responses differ. Avoid extreme elimination diets unless there is another medical reason to use one.

What not to rely on

Do not use sweating or exercise as a “detox” treatment for acne.
Do not apply undiluted tea tree oil, lemon juice, or other irritating DIY remedies to inflamed acne.
Do not assume “natural” means safer or more effective.
Do not pop deep nodules or cysts; this increases inflammation and scarring risk.

When to see a dermatologist

See a dermatologist for deep painful nodules or cysts, acne that is causing scars or dark marks, significant emotional distress, suspected hormonal disorders, or acne that is not improving with consistent over-the-counter treatment. Prescription therapy may include topical or oral medications chosen for the individual.
