Acne Scars: Why Repeating One Laser May Not Be Enough
Treatment Guide · VS LINE CLINIC GANGNAM
A flat red or brown mark after acne is not the same as a depressed scar. Even among depressed scars, shape, depth and tethering differ. Treatment planning starts by separating colour changes from structural changes.
How are acne marks different from scars?
Flat red or brown areas primarily involve colour. A true depression or raised area involves a change in skin structure. Both can occur together. Improvement in pigmentation should not be mistaken for correction of a deep scar, so the two goals need separate assessment.
Why classify ice-pick, boxcar and rolling scars?
Narrow deep pits, sharply bordered depressions and broad rolling hollows present different problems. Several types can coexist. Classification guides discussion; it is not an automatic treatment prescription. Skin thickness, tone, scar distribution and the individual’s recovery constraints also influence the plan.[1]
When are treatments other than laser discussed?
Selected tethered scars may warrant an approach such as subcision, while narrow deep scars may prompt discussion of focal chemical or surgical treatment. Each carries risks, including bleeding, infection and pigment or scar changes. These are clinician-performed procedures, not techniques to reproduce at home.
Should active acne be controlled first?
Ongoing inflammatory acne can create new scars while older ones are being treated. Control of active disease should be part of the sequence. Disclose medicines, previous procedures and pigmentation problems. Combining every procedure on one day is not automatically the most effective or appropriate approach.
How much improvement is realistic?
Completely scar-free skin cannot be promised. Goals may include softer depressions, less shadowing and improved texture, weighed against downtime. Photograph the skin under consistent lighting. If progress stalls, reassess the scar type and treatment strategy before simply adding more sessions.
Before your consultation
For acne-scar treatment in Gangnam, ask for a scar-specific plan and a realistic definition of improvement.
What do FDA records and clinical studies say?
Potenza. Potenza is FDA-cleared; K231216 specifies electrocoagulation and hemostasis in dermatologic and general surgical procedures. This is not blanket clearance of every pore or scar protocol, or of delivery or combination treatment with Juvelook. Evidence for the proposed goal and the tip, depth and energy plan still need individual assessment.[FP][RF2]

Planning repeat visits or a trip to Korea
If you live locally, discuss when you can return. If visiting Korea, share your arrival, departure and important event dates. English, Chinese and Japanese interpretation is available; request your preferred language when booking and confirm whether the consultation uses an interpreter or a clinician speaking that language. Confirm the treating clinician and appointment availability.
What should you arrange before leaving?
Ask for aftercare instructions, the timing of any review, whom to contact about a concern and which symptoms need medical attention. Before returning abroad, confirm how to contact the clinic and request treatment records, including the available language and issue process. Seek medical assessment for suspected complications rather than waiting only for an online reply.
