Final answer:
Brush cleansing is unsuitable for sensitive skin due to the potential for irritation. People with sensitive skin should use a gentle, non-abrasive cleanser with their fingertips and refrain from scrubbing.
Step-by-step explanation:
The question is about brush cleansing, which is a skincare routine, and its suitability for different skin types. Brush cleansing is unsuitable for sensitive skin because individuals with this skin type can experience irritation or inflammation due to the mechanical action of the brush.
While all-purpose cleansers are formulated to be effective on a variety of dirt types and are generally safe for most surfaces due to their neutral or weakly alkaline solutions, when it comes to skincare, it's especially important to be cautious with sensitive skin. Instead, it is recommended that those with sensitive skin use their fingertips to apply a gentle, non-abrasive cleanser and to avoid scrubbing, which can aggravate certain skin conditions like acne.
