Is Your Skin as Healthy as It Looks? Find Out with a Woods Lamp Test

What is a Woods Lamp Test?

A Woods Lamp Test is a type of ultraviolet (UV) light examination that allows dermatologists to detect various skin conditions that may not be visible under normal lighting. The test is performed using a specialized black light that highlights skin abnormalities by causing affected areas to fluoresce in different colors.

What Can a Woods Lamp Detect?

The Woods Lamp Test is useful in diagnosing a variety of skin conditions, including:

• Fungal Infections – Certain fungal infections, like tinea versicolor, may glow yellow-green under the light.

• Bacterial Infections – Bacteria such as Pseudomonas aeruginosa can produce a green fluorescence.

• Pigmentation Disorders – Conditions like vitiligo and melasma appear more prominently under UV light, helping with diagnosis and treatment planning.

• Skin Thickening or Thinning – Some dermatological conditions affect the skin’s texture, which can be more evident under a Woods Lamp.

• Sun Damage and Premature Aging – Areas of sun damage may be highlighted under the light, revealing hidden damage before visible signs appear.

• Porphyria and Other Metabolic Disorders – Some rare metabolic conditions cause changes in skin fluorescence.

Who Should Consider a Woods Lamp Test?

Anyone experiencing unexplained skin discoloration, persistent rashes, or suspected infections may benefit from a Woods Lamp Test. It is also an excellent tool for those undergoing skin treatments, as it helps dermatologists track progress and effectiveness.

What to Expect During the Test

The procedure is quick, painless, and non-invasive. Here’s what happens:

• The dermatologist will darken the room to allow better visibility under the Woods Lamp.

• The light will be passed over your skin, and different colors of fluorescence will indicate potential concerns.

• Based on the findings, your dermatologist will recommend the best course of action.
