1. For skin acne inspection:
Propionibacterium acne is the key factor in the development of skin acne vulgaris --- comedones (blackheads and whiteheads), papules (pinheads), pustules (pimples), nodules (large papules), cysts and scars. Propionibacterium acne will produce porphyrin during the process of catabolism. Under UV light, this material will appear in fluorescent brownish-red or orange-red color. The intensity of fluorescence and the number of infected bacteria are significantly related. Hence, it is very ideal to use UV light to discover skin acne, for early detection & early treatment.
2. For skin pigmentation inspection:

Some other pigmentation disorders such as freckles, café au lait spots, neurofibromatosis moles, lentigines, age spots also become darker under UV light inspection, It makes analysis & research more earlier.
