Final answer:
High-frequency treatments on acne-prone skin have a germicidal effect, generating ozone that reduces microbial load and targets bacteria, helping soothe inflamed skin and reduce acne.
Step-by-step explanation:
High-frequency current treatments on acne-prone skin or after extraction treatments can have a germicidal effect. When applied, the high-frequency current generates ozone which has antibacterial properties. This effectively reduces microbial load on the skin, targeting bacteria like Propionibacterium acnes which are responsible for the inflammation and infection within clogged hair follicles. By decreasing the bacterial presence, high-frequency treatment can aid in soothing inflamed skin and reducing the occurrence of acne lesions.
