What is Phototesting?
Phototesting is a diagnostic procedure used to assess how your skin reacts to UV light. It involves exposing small areas of skin to different wavelengths to determine the minimal erythema dose (MED), which is the smallest amount of UV that causes redness.
Why Phototesting Matters
Identifying the MED can help doctors pinpoint the type of photosensitivity you have, whether it's triggered by UVA, UVB, or visible light. This information is crucial for tailoring effective treatment plans and photoprotection strategies.
Preparing for Phototesting
Before undergoing phototesting, patients must stop using certain medications and topical agents to avoid interference with results. This preparation ensures that the test accurately reflects the skin's response to UV exposure.
