The honest framing
Common skin bumps — sebaceous hyperplasia, skin tags, milia — are easily addressed in Korean clinics with refined techniques and excellent cosmetic outcomes. The patients who do well confirm benign nature first (especially for new or changing lesions), allow Korean dermatology\'s efficient removal techniques to address concerns, and follow maintenance routines to minimize recurrence. The patients who attempt home removal often face scarring or incomplete removal. Korean clinics offer these procedures at competitive cost with minimal downtime — they\'re among the most cost-effective cosmetic improvements available.
