Dr. Seungmin Oh addresses common questions about skin treatments. Filler treatments are suitable for individuals in their 20s, or at any age, if desired to enhance facial contours. For nasolabial folds and skin laxity, various treatments such as Ulthera, Thermage, and stem cell therapy may be recommended depending on the condition. Specifically, Ulthera is possible two weeks after stem cell treatment, but for bruised areas, ultrasound-based Ulthera is safer than electricity-based Thermage. Accurate treatment recommendations are provided through in-person consultations.
