For skin lesions and ulcers, what ultrasound frequency is recommended?

• A. 3 MHz or higher
• B. 1 Hz
• C. 0.5 MHz
• D. 5 MHz or lower

Answer: (A)

When treating skin lesions and ulcers, you want the ultrasound energy to act primarily on the surface layers of the skin. Higher-frequency ultrasound is attenuated more quickly, so most of its energy stays in the superficial tissues rather than penetrating deeper. This shallow penetration is ideal for heating and stimulating healing in the epidermis and dermis, increasing blood flow and promoting tissue repair without risking deeper structures. Lower frequencies go deeper, which isn’t needed for superficial targets and can increase the chance of affecting underlying tissues. So, a higher-frequency setting is the best choice for skin-level lesions and ulcers.
