[Key Findings]
The key to distinguishing blisters around the mouth from acne is that cold sores (herpes labialis) often appear as clusters of small blisters accompanied by itching or a tingling sensation. Because the herpes simplex virus remains latent in the nerve ganglia, it frequently recurs due to triggers like fatigue, stress, or UV rays. Angular cheilitis, characterized by cracked corners of the mouth, is caused by dryness, bacterial/fungal infections, or Vitamin B deficiency, and is primarily treated through moisturizing and nutritional improvement.
- 57.3% have mistaken blisters around the mouth for "acne."
- 41.7% of those with recurring cold sores experience them 3 or more times per year.
- Only 28.3% receive appropriate treatment when a cold sore occurs.

[Detailed Results]
1. Approximately 60% have mistaken blisters for acne
57.3% of respondents reported mistaking blisters for acne. Because the affected area is similar, confusion between cold sores and acne is common, potentially delaying appropriate treatment.
2. Only 23.7% can correctly distinguish between the two
Only 23.7% could correctly explain the difference between cold sores and acne, while 38.0% stated they either don't know the difference or are unaware of cold sores themselves. This lack of understanding leads to incorrect self-judgment.
3. Over 40% of recurrent sufferers experience 3+ outbreaks per year
41.7% of recurrent sufferers experience cold sores 3 or more times a year, indicating that many are distressed by frequent recurrence. This highlights the importance of lifestyle improvements for prevention and early treatment.
4. Only 28.3% visit appropriate medical institutions; most rely on OTC drugs
Regarding treatment methods when cold sore symptoms appear, only 28.3% visit a dermatologist.
