What is a key characteristic of a magnifying lamp?

A magnifying lamp is specifically designed to assist estheticians in closely analyzing the skin during facials or skin assessments. The primary feature of this tool is its ability to enlarge the view of the skin, allowing the practitioner to observe fine details that may not be visible to the naked eye. This capability is crucial in identifying skin conditions, assessing texture, and determining appropriate treatments.

While other characteristics like brightness settings or portability can be beneficial, they do not define the primary function of a magnifying lamp. The key characteristic remains its focal purpose—enhancing the visual examination of skin to ensure that the esthetician can provide accurate analysis and effective treatment recommendations. Understanding this function is essential for effective practice in esthetics.
