Hello. This is Hyundo-ju from Therapy Dermatology.
Acne scars left behind after breakouts can be a major source of stress every time you look in the mirror. Many people visit our clinic feeling discouraged because the scars are difficult to conceal with makeup and become more prominent under lighting. Today, we'll briefly summarize the key aspects of acne scar treatment to help you overcome these deep concerns.
1. What kind of scars are on my face? Types of acne scars

The beginning of scar treatment is ‘The Shape of My Scar’is to accurately identify it. This is because the treatment method changes completely depending on the shape.
- Ice pick scar It's a scar with a narrow opening, deeply indented as if pierced by an ice pick. It's commonly found on the nose or cheeks and is considered difficult to treat.
- Boxcar scar It is a scar with a clear, vertical, cliff-like border. It is similar to a chickenpox scar, and the process of making the borders smooth is essential.
- Rolling scar The fibrous tissue under the skin is pulling, causing the scar to have a rounded and gently indented shape. It appears uneven depending on the lighting and becomes more prominent when elasticity decreases.
2. Acne Scars: Why Combination Therapy is the Answer
Most patients have multiple types of scars at the same time, not just one. Therefore, rather than a single device, focusing on both the surface and deeper layers of the skin Complex therapyis essential.
- Erbium fractional laser: It finely shaves down the sharp edges of scars to smooth them out. It is very effective for treating boxcar scars.
- RF Needle Therapy High-frequency energy is delivered directly to the dermis through micro-needles. This induces collagen regeneration, plumping the skin from the inside out.
- Subcision: This procedure is for cutting the ‘hard fibrous bands under the skin' that cause rolling scars. Releasing the adhesion allows the depressed skin to rise properly.
- Collagen Booster Rithuo, JuvelookIt accelerates skin regeneration and fills in volume by injecting similar components. Treatment Duration of effectIt is a reliable helper that increases.
Subcision is particularly important when treating old pitted scars. Instead of simply dissecting with a needle, it is much more effective to use a CO2 gas injector in conjunction with injecting a collagen booster.

4. Pain and downtime, how long will it take?
Scar treatment involves regenerating new skin, so some level of stimulation is unavoidable.

- Downtime (recovery period): It depends on the intensity of the procedure, but it typically takes about 3 to 7 days. Red flagI may develop fine scales.

6. FAQ (Frequently Asked Questions)
How long does the effect last?
A. Unlike anti-aging treatments, acne scar treatments do not easily lose regenerated skin once it has filled in. While the improved effects from the procedure are semi-permanent, they can reappear if skin elasticity decreases, so it's advisable to manage elasticity consistently in conjunction with treatments.
A. How many treatments will it take to see results?
A. While there are significant individual differences, we generally recommend 3-5 sessions or more at one-month intervals. You may notice an improvement in texture after even one session, but deep scars require repeated stimulation.
Q. Can I wash my face immediately after the procedure?
A. It depends on the treatment equipment, but light cleansing is usually possible on the evening of the same day or the next day. Regenerative ointment and sunscreen are essential.
