Which treatment utilizes sound waves to enhance skin repair?

The treatment that utilizes sound waves to enhance skin repair is ultrasound. This technique works by producing high-frequency sound waves that penetrate the skin, generating thermal and mechanical effects in the tissue. These sound waves stimulate the production of collagen and elastin, both essential proteins that contribute to skin elasticity and firmness. The resulting increase in blood circulation promotes healing, reduces inflammation, and enhances the overall appearance of the skin.

In comparison, cryotherapy involves extreme cold to treat inflammation and pain, electrotherapy uses electrical currents for muscle stimulation and pain management, and microcurrent therapy applies low-level electrical currents to stimulate facial muscles and improve skin tone. While these treatments have their own benefits, they do not utilize sound waves for skin repair like ultrasound does.
