Acne Treatment

Medical-Grade Acne Extraction

Medical-grade comedone extraction is a procedure that removes blackheads, whiteheads, and pustules that have formed a core under sterile conditions. The process involves disinfecting the area, softening the comedone, and creating an exit pathway with a sterile needle. The comedone is then extracted using specialized tools with controlled pressure. Finally, the area is disinfected and soothed.

Why Should You Extract Comedones Instead of Popping Them Yourself?

Clogged comedones in hair follicles cause inflammation; topical treatments penetrate poorly through thick comedones. Proper extraction opens a pathway for removal without damaging the follicle wall. Popping with hands or non-sterile tools often pushes the comedone deeper, tears the follicle wall, and pushes bacteria into the dermis — resulting in more severe inflammation, hyperpigmentation, and pitted scars. This is the most common cause of pitted scars in young individuals.

How is Extraction Different from Popping at a Spa?

Three key points: Indication — the dermatologist examines the skin and identifies which comedones can be extracted (blackheads, whiteheads, pus-filled comedones) and which cannot (red inflamed comedones that are not ready, cysts, nodules, corticoid-induced acne); Technique — creating an exit pathway with a sterile needle in the direction of the follicle, applying moderate pressure without excessive force; Sterility and Post-Procedure Care — using sterilized tools, disinfecting, applying topical anti-inflammatory treatments or soothing light therapy, along with a prescribed skincare regimen. Extraction is a step in acne treatment, not a standalone procedure.

Indications

Deep closed comedones, blackheads in the nose-chin area, whiteheads, and pus-filled comedones that have formed on skin undergoing treatment; before peels or laser treatments on the same day. The frequency is typically every 2–4 weeks during the initial treatment phase, decreasing as the skin stabilizes.

Risks to Be Aware Of

Redness and slight swelling for a few hours to 1–2 days; temporary hyperpigmentation at the extraction site (reduced with sun protection); increased inflammation if unripe comedones are extracted; scarring if excessive force is used or if deep inflamed comedones are extracted; infection if tools are not sterile. Over-frequent extraction can irritate the skin.

At BonBoz

The dermatologist examines the skin and identifies each comedone for extraction; the procedure is performed by a trained dermatology nurse under the supervision of the doctor using sterilized tools. After extraction, anti-inflammatory treatments are applied, soothing light therapy may be used, and a prescribed medication regimen is followed. The doctor monitors the number of new comedones at each visit to adjust the treatment plan, avoiding isolated extractions without a treatment strategy.

How is it performed?

Disinfect the skin area; soften the core with warmth or a solution; create an exit point at the top of the core using a sterile needle in the direction of the hair follicle; use a round-tipped extraction tool to gently squeeze from both sides to fully extract the core, without repeated pressure; disinfect each point again; apply a topical anti-inflammatory or use soothing light therapy. The duration is 20–40 minutes depending on the number of lesions.

Before the procedure

Conduct a skin examination and mark areas of extracted acne. Ensure thorough cleansing and makeup removal. If the skin is prone to irritation, discontinue retinoids for 2-3 days. Additionally, report any current medications and history of keloids.

After the procedure

Do not touch or apply makeup for 12–24 hours; gently cleanse the face and use sunscreen; continue the prescribed topical regimen as directed by the doctor; mild redness will subside within 1–2 days; the next session should be scheduled in 2–4 weeks based on progress.

Possible risks — your doctor explains them before treatment

  • Redness and slight swelling for 1-2 days
  • Temporary bruising at the extraction site
  • Worsening inflammation if the pimple is not fully formed
  • Scarring if excessive force is used or if deep inflamed pimples are extracted
  • Infection if aseptic techniques are not followed

Who should NOT have this?

  • Red inflammatory acne without pus, cystic acne, and nodular acne
  • Acne caused by corticosteroids, and folliculitis due to fungi (requires addressing the underlying fungal infection)
  • Skin is currently irritated, with a compromised skin barrier
  • Currently using high-dose isotretinoin (thin skin, prone to scarring)
  • Tendency for keloid scarring in the chest and shoulder areas

Frequently asked questions

Is extracting acne painful?

There is a slight prick when opening the exit; the pressure is moderate, making it relatively painless. Deep inflamed acne should not be extracted, so there is minimal pain sensation.

Will there be any dark spots after extraction?

There may be slight temporary darkening at the extraction site, which fades within a few weeks if sun protection is used; this is much less than the darkening that occurs when extracting on your own.

How often should extractions be done?

Every 2–4 weeks during the initial treatment phase; this frequency decreases as new acne reduces.

Can cystic acne or nodular acne be extracted?

No. Extracting can rupture the cyst into the dermis, causing inflammation to spread and scarring. The doctor will treat it with medication and may inject anti-inflammatory agents at the lesion.

Does extraction completely eliminate acne?

Not by itself; this is a supportive step to allow medication to penetrate and reduce clogging. The medication regimen and new habits ultimately determine the outcome.

How long after extraction can I have a peel or laser treatment?

A light peel can be done immediately in the same session if the skin is stable; laser treatments are usually done 1–2 weeks later.

Is it okay to use a comedone extractor at home?

It is not advisable: lack of sterility, inability to differentiate between extractable and non-extractable acne, and incorrect pressure can cause scarring. This is a common cause of pitted scars.

Will blackheads on the nose return after extraction?

Yes, because the hair follicles still produce oil; combining BHA, retinoids, and regular peels can help reduce recurrence.
