The 2026 evidence supports topical retinoids, especially adapalene 0.1%, as the strongest nonprescription option for removing and preventing blackheads. Salicylic acid may help, while squeezing and repeated extraction offer short-lived clearing with greater risk. A blackhead is an open pore containing oil, bacteria, and dead skin cells. Its dark surface is not dirt, so harder scrubbing will not clean it away and may worsen acne.

What works best for blackheads?
Topical retinoids keep pores from becoming clogged. The 2024 American Academy of Dermatology guideline strongly recommends them for acne after 20 studies showed benefit; adapalene 0.1% is the nonprescription retinoid used to unclog pores and prevent blackheads, according to the Journal of the American Academy of Dermatology guideline. Apply adapalene sparingly across the blackhead-prone area rather than dabbing it only on visible plugs.
This area-based approach treats developing clogs as well as existing ones. Expect gradual improvement, not overnight removal. The AAD advises giving adapalene-based care six to eight weeks to work before judging the result.
Where does salicylic acid fit?
Salicylic acid is a reasonable alternative when a retinoid is unsuitable or too irritating, but its supporting evidence is weaker. The AAD conditionally recommends it based on one randomized trial. In that trial, 0.5% salicylic acid produced an 11% greater reduction in open comedones than the inactive vehicle after 12 weeks.
It did not improve closed comedones. Open comedones are blackheads; closed comedones are small, skin-colored or white clogged pores. This difference matters when choosing a product. Salicylic acid may target visible blackheads, but the evidence does not establish equal performance across every type of clogged pore.
A practical treatment routine
Keep the routine simple enough to follow consistently: Pregnant patients should not use topical retinoids such as adapalene or tretinoin, according to the UK National Health Service acne guidance. They should discuss a suitable alternative with a healthcare professional.
Benzoyl peroxide and azelaic acid also produced favorable results in the evidence reviewed by Europe's 2025 guideline. However, that guideline downgraded every recommendation for predominantly comedonal acne because only one trial directly studied that specific patient group.
- Wash gently rather than scrubbing the dark material.
- Apply a thin layer of adapalene 0.1% across the affected area.
- Use UV protection because retinoids can increase sun sensitivity.
- Reduce application frequency if irritation develops.
- Reassess after six to eight weeks rather than extracting each new plug.
Why extraction is not the main solution
Dermatologist-performed extraction can clear resistant blackheads immediately. A dermatologist uses sterile instruments, which makes professional removal safer than squeezing at home. Extraction is rarely the first treatment because it takes time, may be expensive, and does not stop blackheads from returning.
Preventive treatment remains necessary after the visible plugs are removed. At-home squeezing can push material deeper, increase inflammation, delay clearing, and lead to infection or permanent scarring. The American Academy of Dermatology advises against popping acne, making treatment of the whole affected area the safer long-term strategy.
What the evidence still limits
The evidence is strongest for acne broadly, not for people whose acne consists mainly of blackheads. That explains why topical retinoids receive strong support in the AAD guideline while European recommendations for comedonal acne remain downgraded. Results also depend on the outcome being measured. A treatment may reduce open comedones without helping closed ones, as the salicylic acid trial demonstrated.
Product strength, irritation, consistent use, and the mix of lesion types all affect the practical choice. Benzoyl peroxide requires one additional product check. In 2025, FDA testing found elevated benzene in six of 95 tested acne products, while more than 90% contained undetectable or extremely low levels. The FDA advised checking voluntary recalls and discarding expired products, rather than abandoning benzoyl peroxide categorically.
