Korean Acne Scar Treatment Before and After: What Changes, How Fast, and How to Read the Photos

I'm Dr. Hyunji Kim, Director and Lead Physician at Delphic Clinic in Gangnam. I trained at Korea University Medical Center and I'm a member of the Korean Society for Laser Dermatology & Hair. Acne scars are one of the conditions I treat most with lasers and microneedling.

Korean acne scar treatment before and after photos are usually what brings people to my chair, often saved on their phone. I understand why. But a photo shows the result, not the months and sessions behind it. This guide explains what realistically changes, how fast, and how to read the photos you find.

What changes by scar type

I explain each type and how to tell them apart in my guide to acne scar treatment by scar type.

The timeline behind a before and after

• Week 1: redness and fine marks; skin can look worse before it looks better.
• Weeks 2–4: surface settles; early softening in good light.
• Months 2–3: collagen remodelling shows; this is where honest 'after' photos come from.
• After several sessions: the change you see in most published pairs.

A real acne scar 'after' photo is taken months later, in the same light. Anything sooner is a promise, not a result.— Dr. Hyunji Kim, Delphic Clinic

How to read the photos you find

1. 1Same light and angle? Side light makes scars look deeper; front light flattens them.
2. 2Makeup or filters in the after shot?
3. 3How many sessions, and how long after the last one?
4. 4Same scar type as yours?

What it costs at our clinic

Budgets by scar type are worked through in my acne scar cost guide, and our Potenza treatment page lists each tip. For depressed scars, Rejuran S can be added between sessions.

Who should wait

• Active breakouts: control acne first, then treat scars.
• Recent isotretinoin use: discuss timing with us first.
• Tanned skin or planned sun exposure after treatment.
• Expecting one session to erase scars before an event.

Consultation at Delphic Clinic is free, English and Chinese interpreters are on site, and we're near Sinnonhyeon Station Exit 3. Send daylight photos from the front and both sides, and I'll tell you which scar types you have and what change is realistic.
