73.7% of Patients Compare 3+ Treatment Methods for Acne Scar Craters | I-See Clinic Survey

Survey Key Points

In conclusion, improvement for acne scar craters can be expected through consistent and appropriate treatment. Dermapen is suited for shallow craters, subcision for deep craters, and fractional lasers for extensive cases. Costs typically range from 20,000 to 100,000 JPY per session, with 3 to 6 sessions often required to experience visible results.

Our survey revealed that 73.7% of individuals actively compare at least three treatment methods, with 48.3% citing 'durability of effects' as the most crucial factor in their selection. Additionally, 62.0% of those suffering from deep craters show strong interest in subcision therapy.

Comparison of the Three Major Treatments

### 1. Dermapen Promotes collagen production through micro-needling. Suitable for shallow to moderate scarring, costing 20,000–40,000 JPY with 3–5 sessions.

### 2. Subcision Physically releases fibrous adhesions with a specialized needle to lift depressions. Highly effective for deep boxcar or rolling craters. Costs 30,000–80,000 JPY with visible results in 1–3 sessions.

### 3. Fractional Laser Uses heat-induced remodeling via point-like irradiation. Ideal for extensive acne scars. Costs 50,000–100,000 JPY with 3–5 sessions.

Detailed Findings

- **Information Gathering**: 73.7% engage in multiple comparisons, reflecting a diversifying treatment landscape. - **Depth Perception**: 58.7% identify their scars as 'moderate to deep,' suggesting that medical diagnosis is necessary for most cases. - **Timeline Expectations**: 67.3% hope for visible improvement within six months, though gradual, consistent treatment is required.

Dr. Kota Takakuwa emphasizes that an accurate diagnosis by a specialist is the vital first step, given that different types of craters—icepick, boxcar, and rolling—require tailored approaches.
