High-frequency treatments are generally used to address various skin concerns, including acne and oily skin, due to their ability to promote healing and reduce inflammation. These treatments involve the application of a high-frequency electrical current that stimulates cellular activity and enhances blood circulation, which can be beneficial for managing oil production and reducing acne lesions.

However, for individuals with rosacea or sensitive skin, high-frequency treatments are not suitable. This is primarily due to the nature of high-frequency stimulation, which may exacerbate irritation and sensitivity in already compromised skin conditions like rosacea. Rosacea is characterized by redness and inflammation, and the heat generated during high-frequency treatments can worsen these symptoms, leading to increased discomfort and exacerbation of the condition.

In contrast, oily skin can benefit from high-frequency due to its sebum-reducing properties, and dry skin may not be negatively impacted as much by the treatment compared to sensitive skin. Thus, the correct identification of rosacea or sensitive skin indicates a crucial understanding of how different skin types react to various treatments, highlighting the need for tailored approaches in skincare.
