What type of substances can not only be removed but also handled with care in a cosmetic setting?

The correct answer is that non-living epidermis can be removed and handled with care in a cosmetic setting. The epidermis, which is the outermost layer of skin, consists primarily of dead skin cells and is not vital for the overall function of living tissues. This means that trained cosmetologists can safely work with and remove this layer during various cosmetic procedures, such as exfoliation or skin treatments, without causing harm to the underlying structures that support skin health.

Handling the non-living epidermis allows professionals to improve skin texture and appearance while ensuring that they are not interfering with living tissues or structures that require careful consideration and protection. In contrast, the dermis layers and living tissues are vital components of skin anatomy that require specialized techniques and caution due to their role in maintaining overall skin health and integrity. Excessive hormones are also not something that can simply be handled or removed in a cosmetic setting, as they pertain to internal bodily functions that are beyond the scope of cosmetology practice. Therefore, focusing on the non-living epidermis aligns with the principles of safety and effectiveness in cosmetic procedures.
