Blackheads are open comedones—pores widened by oil and dead skin cells—and their dark color comes from oxidation, not dirt. In 2026, evidence supports several acne treatments, but results take time and safety depends on the product, pregnancy status, and acne severity. A few blackheads may respond to over-the-counter care. Painful nodules, scarring, significant distress, or acne that persists despite pharmacy treatment warrants medical advice.

Which treatments have evidence?
The American Academy of Dermatology supports benzoyl peroxide, topical retinoids, salicylic acid, azelaic acid, and combination topical therapy. Retinoids are especially relevant to blackheads because they help clear clogged pores, according to the AAD acne guideline. Choose one suitable treatment and follow its directions instead of starting several irritating products together.
Benefits commonly take about six weeks, so changing products every few days makes effectiveness difficult to judge. Over-the-counter treatment has limits. A product that improves scattered blackheads may not adequately treat widespread acne, deep lesions, or existing scars.
What safety warnings matter?
Benzoyl peroxide can irritate skin, increase sun sensitivity, and bleach hair or fabric. Avoid contact with colored towels, pillowcases, and clothing while using it.
The FDA has reported rare but potentially life-threatening hypersensitivity reactions involving some benzoyl-peroxide or salicylic-acid acne products. Stop using the product and seek emergency help for throat tightness, breathing difficulty, faintness, facial swelling, hives, or itching, as described in the FDA safety communication. Do not treat severe irritation as proof that a product is "working." Follow the label and ask a pharmacist or clinician whether the treatment suits your skin and other products.
What should you avoid doing at home?
Do not squeeze or repeatedly pick blackheads. Pressure can damage surrounding skin and lead to infection or permanent scarring. Home chemical peels create a different level of risk.
The FDA says it has approved no chemical-peel products for use without professional supervision and warns that concentrated acids can cause burns, infection, skin-color changes, and disfiguring scars in its chemical-peel warning. Avoid oil-based or comedogenic cosmetics, meaning products likely to block pores. Evidence does not support prescribing one specific acne diet, so restrictive eating plans should not replace appropriate skin care or treatment.
What changes during pregnancy?
Anyone who is pregnant or could become pregnant should ask a clinician before beginning acne treatment. Topical retinoids are unsuitable during pregnancy because of birth-defect risk.
The NHS states that topical benzoyl peroxide can be used during pregnancy. Its pregnancy guidance does not make every acne product interchangeable, so check each active ingredient rather than relying on the brand name.
When should you ask for medical help?
If topical treatment has not helped after six to eight weeks, ask a clinician about the next step. Options may include prescription treatment or professional comedone extraction rather than home squeezing. Seek medical assessment sooner for painful nodules, scarring, significant emotional distress, or acne that has not responded to pharmacy treatment.
These features may justify referral for specialist care. Isotretinoin is reserved for severe acne that has resisted other treatment. It carries substantial side-effect and pregnancy risks, so its use requires medical assessment rather than self-treatment.
