Final answer:
The best tool to analyze the skin is Magnifying lamp/light (Option B).
Step-by-step explanation:
The best tool for skin analysis is a magnifying lamp/light, as it offers a detailed view of the skin, which is essential for identifying various skin conditions. Papillae, important for hair structure and nutrition, extend from the epidermis down into the dermis.
This tool allows for a detailed examination of the skin's surface, helping to identify issues such as dryness, oiliness, clogged pores, or other skin conditions. It provides a magnified view of the skin, which is vital for a thorough skin analysis and it is widely used in esthetics and dermatology.
In contrast, a lancet is used for pr*cking the skin, an esthetician's fingers can be used to feel for textures and irregularities, and blotting paper can be used to check for oiliness but isn't as comprehensive as a magnifying lamp.
Thus, the correct option is B.
