Closed comedones are small, skin-coloured bumps caused by a blocked hair follicle. They are often called whiteheads, although they may not look white. Unlike a blackhead, the surface opening is covered, so the trapped mixture of oil and dead skin cells is not exposed to air.
They are common on the forehead, cheeks and chin. They are not caused by poor hygiene, and trying to scrub or squeeze them away usually makes the skin more irritated.
What is a closed comedone?
Each follicle contains a tiny oil-producing gland. Oil, known as sebum, normally travels to the surface with shed skin cells. When those cells become sticky and collect inside the follicle, they can form a plug. If the opening remains sealed, the result is a closed comedone: a firm, flesh-coloured bump that is usually not red or painful.
An open comedone, or blackhead, has an exposed opening. Its dark colour comes from oxidation, not dirt. If a blocked follicle becomes inflamed, it may develop into a red papule, pustule or deeper spot.
Could the bumps be something else?
Not every small facial bump is a closed comedone. Milia are tiny, firm keratin cysts that are particularly common around the eyes. Folliculitis may appear suddenly as itchy or tender bumps centred on hairs. Perioral dermatitis tends to cause a red or burning rash around the mouth, nose or eyes and usually lacks comedones.
If the diagnosis is unclear, do not keep adding stronger exfoliants. A GP, dermatologist or appropriate skin professional can assess the pattern first.
Why do closed comedones form?
Several factors can contribute:
- increased sebum production, often influenced by hormones;
- dead cells not shedding normally inside the follicle;
- heavy or occlusive cosmetics and hair products;
- friction from hats, helmets or tight face coverings; and
- a routine that is either too harsh or poorly matched to the skin.
Washing repeatedly does not correct what is happening inside the follicle. It may instead damage the skin barrier and make treatment harder to tolerate.
A simple routine for closed comedones
Results take time because treatment needs to reduce existing plugs and prevent new ones forming. Introduce one active product slowly, then assess it over six to eight weeks rather than changing the routine every few days.
Morning
- Cleanse gently. Use lukewarm water and a mild cleanser such as Medik8 Total Moisture Daily Cleansing Gel. Avoid cleansing brushes and grainy scrubs.
- Moisturise. Choose a light, non-comedogenic moisturiser that keeps the barrier comfortable.
- Protect. Use broad-spectrum sunscreen every day. Medik8 Advanced Day Ultimate Protect SPF 50+ combines moisturiser and high daily protection.
Evening
- Remove make-up and sunscreen without rubbing, then cleanse gently.
- Choose one 2% salicylic acid product: either Medik8 Press & Clear or Obagi CLENZIderm M.D. Pore Therapy. Salicylic acid is oil-soluble, helping it work within oily pores. Begin two evenings weekly, then increase gradually only if there is no persistent stinging, redness or flaking.
- Use a simple moisturiser. The Dr Motox Exosome Collagen Face & Neck Sheet Mask is a staple hydration step for dry, oily and sensitive skin types and can be used on non-acid evenings whenever extra moisture is needed. Patch test first and avoid infected, broken or actively inflamed skin.
Do not use both salicylic acid products together. If you already use retinal, another retinoid or an exfoliating acid, alternate nights initially instead of layering them. Prescription retinoids such as adapalene or tretinoin have established evidence for comedonal acne, but suitability should be discussed with a clinician.
What should you avoid?
- Squeezing or puncturing bumps at home: this can cause inflammation, infection, pigment change and scarring.
- Daily scrubbing: friction does not remove a deep follicular plug.
- Starting several actives together: irritation makes it impossible to identify which product caused the problem.
- Using rich hair products along the forehead: keep pomades and heavy conditioners away from breakout-prone skin.
Can a professional facial help?
A correctly selected facial can support a home routine through controlled exfoliation and, when appropriate, professional extraction. The Dr Motox Bespoke Facial is tailored to the skin on the day and may include deep cleansing, exfoliation or extractions. It does not replace medical acne treatment, and active inflammation should be assessed before treatment.
Do not book microneedling while taking isotretinoin (Roaccutane). If you are taking isotretinoin or prescription acne medication, follow your prescriber’s skincare and procedure advice rather than adding acids or treatments independently.
When should you seek medical advice?
See a GP or dermatologist if the bumps are widespread, painful, rapidly worsening, leaving scars or not improving after a consistent routine. Medical review is also appropriate if acne is affecting confidence or wellbeing. During pregnancy or while trying to conceive, avoid topical retinoids and discuss salicylic acid with your obstetrician, GP or dermatologist before use.
Closed comedones FAQs
How long do closed comedones take to improve?
Allow at least six to eight weeks for a well-tolerated routine. More established congestion may take several months. Improvement should mean fewer new bumps as well as gradual smoothing of existing ones.
Can moisturiser cause closed comedones?
Some rich or occlusive products may contribute in acne-prone individuals, but moisturiser itself is not the enemy. A light, non-comedogenic formula can improve tolerance of salicylic acid or retinoids.
Should closed comedones be extracted?
Not routinely at home. Selected comedones can be extracted by a trained professional using sterile technique, but prevention with an appropriate routine is more important than repeatedly removing individual plugs.
