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.

When should you see a doctor?
- Mụn viêm sưng đỏ, mụn nang đang đau — lấy nhân lúc này dễ để lại sẹo, cần điều trị nội khoa trước.
- Da đang nhiễm trùng hoặc có tổn thương hở.
- Đang dùng isotretinoin — da mỏng và dễ tổn thương hơn bình thường.
- Bạn định lấy nhân định kỳ như một thói quen mà chưa được soi da và có phác đồ.
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
