Oily areas of the face appear as which shade when viewed under a Wood's lamp?

When viewed under a Wood's lamp, oily areas of the face typically fluoresce as a yellow shade. This phenomenon occurs due to the reflection of light off the excess oil and sebum present on the skin's surface. The oil absorbs ultraviolet light and emits a yellow fluorescence, indicating areas of high oil production.

Understanding this is vital for aestheticians as it helps them identify specific skin conditions and tailor treatments accordingly. Oily skin can contribute to issues like acne or enlarged pores, and this visual cue allows professionals to better assess skin health and needs during consultations or treatments.

Other colors observed under a Wood's lamp correspond to different skin conditions: for example, light violet might indicate a presence of certain types of pigmentation, while blue could indicate hydration levels.
