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

When examining the skin under a Wood's lamp, oily areas of the face typically exhibit a yellowish hue. This phenomenon occurs due to the interaction of the lamp's ultraviolet light with the excess sebum produced by the skin. The oil has specific properties that reflect light in this characteristic way, enabling the skincare professional to identify areas of excess oiliness, which can indicate a tendency towards acne or other skin issues.

Understanding the color interpretation under the Wood's lamp is important in esthetics practice, as it assists professionals in assessing skin conditions and tailoring appropriate treatments for each individual's needs. By identifying oily areas, practitioners can recommend targeted products and techniques to manage oil production, improve skin health, and achieve better cosmetic results.
