Comedone Extraction vs Cortisone Injection

Comedone Extraction: A provider clears blackheads and whiteheads with a small tool. The result is immediate and temporary — pores refill within weeks unless a daily treatment changes them.

Cortisone Injection: A tiny shot of diluted steroid into one inflamed acne cyst. It flattens that spot in a few days. It treats the bump, not the acne.

Choose Comedone Extraction if…

Choose for an instant clear-out of blackheads, whiteheads or milia — temporary unless a daily treatment keeps pores clear.

  • Stubborn blackheads or milia
  • An event coming up
  • You're also using a retinoid at home

Choose Cortisone Injection if…

Choose for one painful acne cyst that needs to flatten fast, or for keloids and patchy hair loss.

  • A single painful cyst before an event
  • A raised keloid
  • A patch of alopecia areata
Fine together

Can you have both?

Often used in the same acne visit: extractions for blackheads, a cortisone injection for a single painful cyst.

What is it?

Comedone Extraction

Cortisone Injection

What is it?

It clears clogged pores.

Blackheads and whiteheads are removed by a clinician.

It helps selected plugs.

It does not address every cause of acne.

It is not for inflamed spots.

Nodules and cysts need a different plan.

Pressure can scar.

Excessive force can cause scarring or pigment change.

It is injected into a lesion.

An intralesional steroid calms local inflammation or scarring.

It differs from joint injections.

It is not a systemic steroid treatment.

The diagnosis matters.

Infected or uncertain lesions should not be injected.

Side effects can last.

Skin thinning, fat loss and pigment change may persist.

Can make it worse
Redness and fine superficial vessels across a light-skinned cheek and nose.

Rosacea

Squeezing worsens redness.

Acne scarring on light skin. Small sharply cut pits and broad shallow dips across a cheek, several sitting inside faint flat pink marks, with no active spots.

Acne Scarring

Can cause dents in skin.

Before your treatment

Comedone Extraction
Cortisone Injection
2–4 weeks before

Prep products: Some providers ask for a retinoid or salicylic acid first, which loosens plugs and makes extraction easier.

Not specified
The week before

A few days before: Do not pick: No picking or squeezing at home.

Do not pick: Do not pick, squeeze or heat the spot.

Day of treatment

Comedone Extraction
Cortisone Injection
Before you arrive

Clean face: Come without makeup if you can.

Clean skin: Wash your face and skip makeup on the area.

Arrival & prep

Skin is cleaned and the provider decides which spots can be extracted.

The provider checks that the spot is an inflamed acne cyst and not a boil.

Treatment

The provider presses around the pore with a metal loop or two swabs, opening whiteheads first with a tiny sterile needle.

You feel firm pinching at each spot. A full face takes 10 to 30 minutes. Blackheads are pressure more than pain; whiteheads and deeper plugs sting when opened, and a long run is tiring rather than sharp. A painful spot is not forced.

The skin is wiped with alcohol.

A very fine needle goes just into the bump and a small amount of fluid goes in, under 10 seconds per spot. The sting is sharp for a few seconds, worse if the cyst is already tender, but most people rate it lower than they expect. Numbing does not help much — the needle stick is the whole procedure.

Before you leave

Red, blotchy skin with pink rings where spots were, sometimes pinpoint scabs.

A tiny red dot, sometimes a small raised bleb that flattens within an hour.

After your treatment

Hours 2 to 6: Redness and small raised rings, sometimes into the next day, with occasional pinpoint scabs where a whitehead was opened.

Days 1 to 2: Redness mostly gone.

Days 1 to 2: The bump softens and the ache fades.

Days 2–7

Days 3 to 7: Skin looks normal.

First few days: A pinprick mark, sometimes a small bruise, fading over a few days.

Days 3 to 7: Most cysts are flat.

Time to results

Immediately

24–48 hours for a cyst

How long results last

Weeks; pores refill without daily treatment

Risks

Risks
  • A brown mark that persists
  • Inflamed spots after every session
  • Dent in the skin
  • Lighter patch of skin
  • Visible small vessels

Cost

Per session

With a dermatologist it is often bundled into an acne visit at no extra charge.

Roughly $50 to $250 per office visit in the US, usually billed as an office visit plus a procedure charge rather than per spot.

Insurance

Insurance sometimes covers it when billed as acne surgery at a medical dermatology visit.

Insurance often covers it, since acne cysts count as medical rather than cosmetic.

Questions

Comedone Extraction

Cortisone Injection

Individual Questions
Does extraction get rid of blackheads for good?

No. It empties the pore that day. It refills over 4 to 8 weeks unless a daily retinoid changes how the pore behaves.

Is it better than doing it myself?

Mostly yes — technique and restraint. A provider uses sterile tools, opens closed spots properly, and stops when a spot resists. Home squeezing causes most brown marks and small scars.

Can they extract a cyst?

No. Deep, red, painful lumps have no opening to press through, and forcing one makes it worse. A cortisone injection is the answer.

Does it make pores smaller?

Only in appearance, and briefly. An empty pore looks smaller; pore size does not change.

Does it hurt?

Blackheads feel like firm pinching. Whiteheads sting for a second when opened. Uncomfortable rather than painful.

How fast does a cortisone shot work on a cyst?

Softening begins within 24 to 48 hours and most spots are flat by day three to five. That figure traces back to one small 1983 trial — it matches what dermatologists see but has never been tested at scale. The mark left behind takes weeks longer, and the injection does not speed that up.

Will it leave a dent?

It can. A shallow depression happens when the dose is too strong, so a lower concentration is the main protection. It is uncommon — most dermatologists see it in well under one patient in a hundred — and it often fills in over several months. But it is not reliably temporary. About half the clinicians who do see it report it lasting more than six months, and occasionally it is permanent. That is why you ask what concentration is being used.

Can I get one before an event?

Yes, the most common reason people ask. Aim for three to five days ahead so the swelling has time to drop. A same-day injection rarely looks better by that evening.

Does it stop acne from coming back?

No. It treats only the spot it is injected into. Preventing the next cyst needs a daily treatment plan, and the guidelines call this an add-on.

Is it safe on deeper skin tones?

Yes. The risk is a lighter patch at the site, more noticeable and slower to fade on deeper skin tones. A lower concentration reduces it, so ask.

Is this approved for acne?

Not in the United States, strictly speaking. The FDA labeling lists intralesional use for keloids, alopecia areata, discoid lupus and others. Acne is not on it. Off-label use for an acne cyst is routine, legal and recommended by the American Academy of Dermatology, but almost nobody says it out loud. In the UK, NICE withdrew its recommendation in 2026 after UK-licensed triamcinolone injections stopped being available — a supply and licensing decision, not a safety one.
