Forehead bumps for 4+ months: closed comedones or milia? (Photos)

Question

47-year-old male, Indian skin (Fitzpatrick IV–V). Photos taken clean-shaven, no products on. Forehead bumps, present since at least June 2026: - Adapalene 0.1%, alternate nights, about 3 months. Well tolerated, no purge, no clear change. Stopped late September. - Professional steam extraction on 6 Oct: some soft plugs and some hard white "pearls" came out. - Since then: azelaic acid 15% every morning, daily SPF, and no hair wax. Nose: a few flat dark-brown spots, 2–3 mm, on the bridge and sides, present for [X months]. Questions: 1. Do the forehead bumps look like closed comedones, milia, or something else? 2. If milia, is lancing by a clinician the right fix? Does a retinoid help them? 3. Should I restart adapalene, or would tretinoin or something else work better? 4. What are the nose spots, and how would you treat them on darker skin without causing more pigmentation?

Anna Chacon, MD, FAAD · Answer

Based on your history, the forehead bumps may represent a combination of closed comedones and milia, although other conditions can produce similar-looking bumps. The fact that some plugs were soft while others were firm, white, and pearl-like is a helpful observation, but an in-person examination is needed to distinguish them confidently.

1. Are the forehead bumps closed comedones or milia?

Closed comedones are clogged pores associated with acne and may feel like small, skin-colored bumps. Milia are tiny, firm, keratin-filled cysts that often look like white pearls and typically do not have an obvious pore opening. Other possibilities include sebaceous hyperplasia or, less commonly, other follicular conditions. Their exact appearance and distribution help determine the diagnosis.

2. If they are milia, is extraction the right treatment?

Yes, a clinician can often remove persistent milia using a sterile technique that opens the surface and releases the trapped keratin. Avoid squeezing or puncturing them yourself, as this can cause inflammation, scarring, and post-inflammatory hyperpigmentation, particularly in darker skin tones.

Topical retinoids may help prevent some new milia or improve associated comedonal acne, but they do not reliably eliminate established milia. Professional extraction is often more effective for individual, persistent lesions.

3. Should you restart adapalene or switch to tretinoin?

Since you tolerated adapalene 0.1% for approximately three months without clear improvement, I would first confirm whether the bumps are actually comedones before escalating treatment. If they are closed comedones, restarting adapalene consistently may still be reasonable, as three months of treatment does not always produce complete clearance. However, if the bumps are primarily milia, switching to a stronger retinoid may not solve the problem.

Tretinoin can be effective for comedonal acne and may improve uneven pigmentation over time, but it can also cause irritation. With Fitzpatrick IV–V skin, irritation is particularly important to avoid because it can trigger additional dark marks. If a retinoid is restarted, introduce it gradually, use a gentle moisturizer, and continue daily broad-spectrum SPF 30–50. Avoid applying it to irritated skin, and do not combine several potentially irritating products at once.

4. What are the dark-brown spots on the nose, and how should they be treated?

Small, flat brown spots can represent post-inflammatory hyperpigmentation, solar lentigines, or other benign pigmented lesions. Their appearance alone is not enough to establish the diagnosis, especially without knowing how long they have been present or whether they are changing.

For darker skin, I generally favor a conservative approach that minimizes irritation. Daily broad-spectrum sunscreen is essential, and azelaic acid 15% can help improve certain types of pigmentation over time. If the spots persist, a clinician should examine them before recommending targeted treatment. Depending on the diagnosis, options may include prescription topical agents or selected procedures, but aggressive peels and lasers can sometimes worsen pigmentation in Fitzpatrick IV–V skin.

Any spot that is new and changing, asymmetrical, irregularly colored, bleeding, or growing should be examined promptly rather than treated as a cosmetic concern.

My overall recommendation: Confirm the diagnosis of the forehead bumps before changing your regimen. If they are milia, professional extraction may be the most direct treatment; if they are closed comedones, a consistent topical retinoid may be more appropriate. For the nose spots, prioritize sun protection and a careful examination before pursuing stronger pigment treatments. The goal is to improve the skin while avoiding unnecessary inflammation and additional pigmentation.
