What is the main benefit of using a Wood's lamp during skin analysis?

The main benefit of using a Wood's lamp during skin analysis is its ability to identify skin conditions under ultraviolet (UV) light. When the Wood's lamp is used, it produces a specific wavelength of UV light that makes certain skin conditions more visible. This can reveal the presence of conditions such as pigmentation issues, bacterial infections, and fungal infections that might not be easily visible to the naked eye under natural light.

Using a Wood's lamp helps beauty specialists diagnose problems like hyperpigmentation, sun damage, and even some vascular conditions effectively. The UV light illuminates these conditions, allowing for a more accurate assessment of skin health and guiding appropriate treatment options.

While the other options may seem relevant, they do not accurately capture the primary purpose of the Wood's lamp. For instance, it does not inherently brighten the skin, assess hydration levels, or remove impurities. These aspects are addressed through other methods or tools in beauty and skincare practice.
