Acne Scar Laser Treatment in Daegu: Why One Session May Not Be Enough
Read the Korean originalSummary For acne scars, the form and goal are distinguished and the progress of several sessions is evaluated. In a study of 20 patients evaluated 90 days after the final procedure after 4 sessions at 4-week intervals, alternating non-ablative laser and RF treatment was not significantly superior to laser alone. Adding more equipment doesn't always mean more benefits.

For acne scars, the form and goal are distinguished and the progress of several sessions is evaluated. In a study of 20 patients evaluated 90 days after the final procedure after 4 sessions at 4-week intervals, alternating non-ablative laser and RF treatment was not significantly superior to laser alone. Adding more equipment doesn't always mean more benefits.
Before your consultation
- Diagnosis is made by distinguishing between pitted scars, red marks, and hyperpigmentation.
- The recovery period and repeat treatment interval are determined in advance.
- Create a plan to combine sun protection and inflammatory acne management.
General information, not a personal diagnosis or treatment plan. Suitability, risks and recovery require an individual consultation.
Why is there an evaluation period even after 4 treatments?
A randomized fractionated facial study compared non-ablative fractionated laser alone with alternating microneedle RF treatment in 20 patients. After 4 treatments at 4-week intervals, the progress was checked 90 days after the last treatment. It is important to note that the results were not evaluated solely by the appearance on the day the session was completed.
The study's finding of no significant difference between the two approaches is at odds with the claim that combination is necessary for all patients. Nor do we generalize that merging is always pointless. You should confirm during your consultation whether the plan suits your scar type and treatment goals.

Create a scar map and consult
Try dividing out the texture of the entire face and the dents that are of particular concern. The goal of counseling becomes clearer if you explain the difference between red or brown marks and the actual treatment area. What is not visible in one bright photo may stand out in different lighting.
The goal of reducing a specific scar and the goal of making the overall skin look smooth may be evaluated differently. It is a good idea to get an explanation in advance about which parts may be left over and how much. Decide what changes you would like to observe rather than expecting them to go away completely.
Before deciding on the next round
Recheck the goals of your first plan and record any current changes and new inconveniences. If your recovery took longer than expected, mention that in your next appointment. You can discuss whether to repeat at the same intensity, adjust the method, or observe.
Keeping the date, equipment, and follow-up information for each procedure will also be helpful when receiving consultation elsewhere. The number of rounds listed in the paper is a study plan and not a required number for everyone. It is necessary to evaluate your condition and adjust your plan.
You need to look at the type of scar first
Pitting scars, red marks, and hyperpigmentation are different problems.
If you repeat the same laser treatment without diagnosis, the expected changes may be delayed.
Indented scars also have different shapes, such as awl-shaped, box-shaped, or wide open scars, and each may respond differently to treatment.
Red marks need to be checked to see if vascular changes remain or if inflammation is still recurring.
Daegu acne scar consultation requires the process of checking the depth and width of the scar, current acne activity, and skin type.
Why repeat treatment is necessary
Scar treatment is a process that induces a skin regeneration response, so it is difficult to expect significant changes all at once.
Treatment intervals should be determined considering the recovery period and possibility of returning to daily life.
Fraxel, picofractional, subcision, and regenerative injections may be combined depending on the type of scar.
Increasing the intensity of the procedure can prolong the recovery period, so a consistently repeatable plan is more important than an unconditional strong treatment.
A good plan is not only about how many sessions you get, but also how your skin reacts to each session and adjusting the intensity and combination.
Lifestyle management also affects results
A combination of sun protection, moisturizing, and management of inflammatory acne can help reduce hyperpigmentation and recurrence.
It is also important not to forcefully remove scabs or dead skin cells after the procedure.
If inflammatory acne continues to appear, it may be better to control acne first rather than treat scars.
It is safe to avoid strong peeling products or home care devices during the period when the skin barrier becomes sensitive after the procedure.
When starting Daegu acne scar laser treatment, it is important to look at the treatment period for a long time and realistically adjust the daily schedule, cost, and recovery period.
Scar consultation planning repeat visits at Jungang-ro
If you are looking into acne scar treatment at Daegu Jungang-ro, not only is it your first treatment, but also consider a schedule when you can come to check the progress. Before visiting Dongseong-ro, it is helpful to organize past laser dates and photos, and indicate which area of the indentation scar or red mark you would like to be evaluated first.
FAQ
Is it better to get both laser and RF?
In the studies cited, alternating treatments were not significantly superior to treatment alone. The need for merging is determined by the scar and goals.
How many times should I receive laser treatment for acne scars?
It depends on the depth and extent of the scar. Usually, several iterations are planned.
Are red marks and pitted scars the same treatment?
It's different. Red marks are closer to vascular/post-inflammatory changes, while pitted scars are closer to changes in skin structure, which may lead to different treatment approaches.
