Closed Comedones on Your Forehead: How to Clear Those Tiny Bumps

Closed comedones are tiny, skin-colored bumps that form when a pore is fully plugged with oil and dead skin, and the forehead is one of the most common places to get them. To clear them, use a retinoid such as adapalene 0.1% or a salicylic acid product over the whole forehead, cut back oily hair and skin products, and give it 8 to 12 weeks.

Below is why the forehead is a magnet for these bumps, the habits that keep them coming back, a simple treatment plan with a week-by-week timeline, and how to tell closed comedones from fungal acne and milia.

What are closed comedones?

Closed comedones are whiteheads: clogged pores that have sealed over at the surface. DermNet describes comedones as skin-colored small bumps frequently found on the forehead and chin, and closed comedones specifically as whiteheads where the follicle is completely blocked. The American Academy of Dermatology (AAD) adds that if the pore closes up, you'll see a tiny bump that looks white or flesh colored.

Many people call them "forehead texture bumps, not acne," because they don't look like pimples. They rarely get red or sore, and you often notice them first by running your fingers across your forehead or seeing makeup sit unevenly. They are still a form of acne, which is good news, because acne treatments work on them.

Why do I get small bumps on my forehead?

The forehead sits where oily hair, styling products, sweat and sunscreen all meet, and each can help keep pores blocked. These are the common culprits.

Hair products and bangs

The AAD has a name for breakouts caused by hair and skin products: acne cosmetica. It tends to show up as whiteheads and tiny flesh-colored bumps along the hairline and forehead, and the AAD notes that a styling product with a lot of oil, such as a pomade, is a likely culprit. The AAD also says the oil from your hair can cause acne on your forehead, and suggests shampooing more often if your hair is oily and keeping hair off your face. Bangs press hair and product against the skin all day, so they're worth a closer look if your bumps sit right under the fringe line.

Heavy sunscreen and makeup

Thick, occlusive products on the forehead can contribute. The AAD recommends a sunscreen that says "non-comedogenic" or "won't clog pores", and DermNet lists oily pomades, isopropyl myristate, propylene glycol and some dyes in cosmetics among the chemicals linked to comedones. Switching products is only useful if you keep wearing sunscreen; pick a lighter, non-comedogenic one instead of skipping it.

Hats, headbands and pillowcases

Anything your hair and products touch can carry them back to your forehead. The AAD suggests washing pillowcases, hats and headbands as part of clearing product-related acne.

Smoking and picking

DermNet notes that comedonal acne is more common in smokers than in non-smokers, and that injury to the follicle from squeezing, abrasive washing, peels or laser treatments can also trigger comedones. Picking at the bumps tends to make things worse; the AAD warns that it will make the acne take longer to clear and increase your risk for scarring and dark spots.

How do I get rid of closed comedones on my forehead?

Combine one comedolytic treatment with fewer pore-clogging products, and apply it to the whole forehead. DermNet recommends comedolytic topical medications applied once or twice daily as a thin smear to the entire area affected, naming salicylic acid, azelaic acid and retinoids. Its topical retinoid page calls retinoids effective first-line treatment for comedonal and inflammatory acne.

The retinoid step

Adapalene is the easiest place to start because you can buy it without a prescription. Differin Gel contains 0.1% adapalene, which was previously prescription only, and its directions are a pea-sized amount once a day on the full face. DermNet notes that among retinoids, adapalene is the least irritating and tretinoin the most, and that retinoids can cause dryness, peeling and sun sensitivity, so pair them with moisturizer and daily sunscreen. If your skin stings or flakes in the first weeks, using it every other night for a while is a common way to settle in. Our adapalene guide walks through the first month.

The salicylic acid step

Salicylic acid (a BHA) is one of the comedolytics DermNet lists for comedonal acne, and it works as an add-on or as an alternative if a retinoid is too much for your skin. A wash is the mildest way to use it; a leave-on BHA a few nights a week, on nights you skip the retinoid, is stronger. Avoid stacking both on the same night at first. Our guide to salicylic acid for clogged pores covers strengths and formats.

A simple forehead routine

Keep the rest of your routine plain while you do this. Adding a scrub, a strong acid toner and a retinoid at the same time is a fast way to irritate the skin and get more bumps.

How long do closed comedones take to go away?

Expect 8 to 12 weeks for a clear difference. The AAD tells people to give treatment six to eight weeks to work, Differin says to use consistently for 12 weeks for best results, and DermNet notes that with retinoids it may take 12 weeks or longer before improvement is seen. If hair products were the trigger, the AAD says it can take 4 to 6 weeks for the acne to clear after you stop using them.

DermNet is blunt about the last row: comedonal acne treatment needs to be continued long-term (sometimes for many years). Stopping once your forehead is smooth usually lets the bumps return. To see whether you're actually improving, our guide to tracking acne progress helps.

When should I see a dermatologist for closed comedones?

See one if your forehead hasn't improved after about two to three months of steady treatment, if the bumps are spreading, or if they're turning into painful pimples. The AAD notes that dermatologists can offer comedo extraction or prescription-strength treatment when blemishes persist, and DermNet lists cautery, cryotherapy and microdermabrasion as options for stubborn comedones.

Closed comedones vs fungal acne vs milia: how do I tell?

Look at whether the bumps itch, whether they're all the same, and whether they feel hard. Here's how the three compare.

Fungal acne

DermNet describes Malassezia folliculitis as an infection of the pilosebaceous unit (the hair follicle and its oil gland) by Malassezia yeasts that causes small, itchy, uniform papules and pustules, and notes that comedones are not seen in it. It most often affects the upper back and chest but can appear on the forehead and hairline. Triggers include hot, humid weather, sweating, heavy emollients or sunscreens and antibiotic use. Treatment uses antifungals such as ketoconazole or selenium sulfide shampoo, so acne products alone won't clear it. Our guide to fungal acne vs regular acne has more detail.

Milia

Milia feel hard and don't squeeze out. DermNet defines a milium as a small cyst containing keratin, most prominent on the eyelids and cheeks, and notes they may clear in weeks or last for months. A doctor can remove them with a sterile needle or blade. If your forehead bumps are firm and white, and retinoid treatment hasn't changed them in months, ask a dermatologist to take a look.

How can a selfie scan help with forehead texture?

Closed comedones fade slowly, and it's easy to give up at week five because you can't see progress in the mirror. Regular photos taken the same way make slow change visible. Pori, an iPhone app, takes a selfie and returns an overall skin score from 0 to 100 with a Pores & Texture category, reading your face region by region, so you can follow the forehead on its own. Its before/after comparison and skin diary let you line up a week of oily styling product or a new sunscreen against how the forehead scored.

A photo can't tell a closed comedone from a milium or fungal acne, and lighting changes how bumpy skin looks, so scan in the same light on bare skin. An app is not a diagnosis; see a dermatologist for itchy, spreading or painful bumps.
