Collagen Induction Therapy in Seoul: Microneedling for Renewal
The short answer
Collagen induction therapy (CIT), or microneedling, creates thousands of tiny controlled punctures that trigger your skin to build new collagen and elastin. In Gangnam a full-face session typically costs about ₩100,000–₩350,000, takes 30–60 minutes including numbing, and causes 1–3 days of redness. Most people book 3–5 sessions four weeks apart, with results developing over 2–3 months.
Key facts
- Treats: mild acne scars, enlarged pores, fine lines, dull texture
- Needle depth: roughly 0.5–2.0 mm depending on the area
- Session time: 30–60 minutes with numbing
- Downtime: 1–3 days of redness and dryness
- Sessions: typically 3–5, about 4 weeks apart
- Typical Seoul price: about ₩100,000–₩350,000 per session
- Common add-ons: PRP, exosomes, PDRN serum
How collagen induction therapy works
Microneedling uses a pen-style device with fine sterile needles that oscillate rapidly over the skin. Each pass leaves microscopic channels that close within hours, but the skin reads them as small wounds. In response it releases growth factors, lays down fresh collagen and elastin, and gradually thickens and smooths the dermis.
Because the surface stays largely intact, CIT is gentler than ablative lasers and is generally suitable for all skin tones, including those prone to pigmentation.
What it can improve
- Shallow rolling and boxcar acne scars
- Enlarged pores on the cheeks and nose
- Fine lines and early crepiness
- Rough texture and dullness
- Mild stretch marks on the body
Deep icepick scars and significant sagging usually need stronger tools, such as fractional laser or RF microneedling, which adds heat for extra tightening.
Microneedling options in Gangnam
| Option | What it adds | Typical downtime |
|---|---|---|
| Standard CIT | Mechanical collagen stimulation | 1–2 days |
| CIT with PRP | Your own platelets for healing support | 2–3 days |
| CIT with exosomes or PDRN | Regenerative serum pushed into channels | 1–3 days |
| RF microneedling | Heat energy at depth for tightening | 2–4 days |
Clinics often recommend microneedling with PRP if scarring is your main concern.
The treatment day
The skin is cleansed and numbing cream is applied for about 30 minutes. The doctor or nurse then works across the face in sections, adjusting depth for thin areas like the forehead and thicker areas like the cheeks. You feel vibration and light scratching. Pinpoint bleeding is normal. A soothing serum or mask finishes the session, and you leave looking as if you have a strong sunburn.
Recovery timeline
Redness fades over 24–72 hours, followed by a few days of tightness and light flaking. Skip makeup for the first day if possible, avoid active ingredients such as retinoids and acids for about five days, and use sunscreen diligently. Swimming pools, saunas and intense exercise are best avoided for 48 hours.
Who should wait or choose another option
Microneedling is widely suitable, but it is not the right choice for everyone at every moment. Doctors usually postpone treatment if you have active, inflamed acne, a cold sore outbreak, eczema or psoriasis flaring on the face, or any skin infection. People with a strong tendency to keloid scarring, bleeding disorders or who are pregnant should discuss alternatives. If you recently finished isotretinoin, the doctor may suggest waiting. Being open about medications and supplements, including blood thinners and fish oil, helps the clinic plan safely and reduces bruising.
How CIT fits with other treatments
Many Gangnam patients use CIT as one part of a wider plan. It pairs well with skin boosters a few weeks later, with gentle laser toning for pigment, and with regular hydrating facials. Spacing treatments properly gives the skin time to recover and lets each one work fully. Ask the doctor to map out a sequence if you intend to combine several procedures across one or more trips.
Session plan and results
New collagen takes time, so the best changes appear four to twelve weeks after a session. For texture and pores, three sessions is a common starting plan; for acne scarring, four to six sessions often gives a more noticeable difference. Results are long-lasting, although natural ageing continues, so many people return for one or two maintenance sessions per year.
Tips for foreign patients
CIT is travel-friendly because downtime is short. If you are in Seoul for a week, have it done early so the redness settles before you fly. Ask whether the clinic uses single-use sterile cartridges, who performs the treatment, and whether add-on serums are included in the quoted price.

Patient questions
Frequently asked questions
Does microneedling hurt?
With numbing cream most people describe it as scratchy and warm rather than painful. Bony areas like the forehead feel more intense.
Can I wear makeup afterwards?
It is best to wait about 24 hours so the micro-channels close and the risk of irritation drops.
Is CIT safe for darker skin?
Yes. Because it does not use heat on the surface, microneedling carries a low risk of pigmentation when aftercare and sun protection are followed.
How is CIT different from RF microneedling?
Standard CIT relies on the needles alone, while RF microneedling releases radiofrequency heat at the needle tips for added tightening and scar remodeling.
When will I see results?
Glow appears within a week, but collagen changes build over 1–3 months after each session.
