It could also be beneficial to rule out certain conditions. Different hypomelanotic conditions can be distinguished using confocal laser scanning microscopy based on patterns of distribution and melanin content. Melanophages are not seen in vitiligo or naevus depigmentosus, but they have been detected in postinflammatory hypopigmentation. [2]
An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining.
There are four UVB types of lamps: Fluorescnt Broad-Band UVB that emit 280-330 nanometer, Fluorescent Narrow-Band that emit 312 nanometer, Excimer that emit 308 nanometer and LED that emit 290-300 nanometer. PUVA means UVA + psoralen. It consists of irradiation of the skin with the UVA ultraviolet light, from a fluorescent bulb or LED lamps.
Vitiligo (/ ˌ v ɪ t ɪ ˈ l aɪ ɡ oʊ /, vit-il-eye-goh) is a chronic autoimmune disorder that causes patches of skin to lose pigment or color. [1] The cause of vitiligo is unknown, but it may be related to immune system changes, genetic factors, stress, or sun exposure.
The pigment loss can be partial (injury to the skin) or complete (caused by vitiligo). It can be temporary (from tinea versicolor) or permanent (from albinism). [1] Most commonly, depigmentation of the skin is linked to people born with vitiligo, which produces differing areas of light and dark skin. Monobenzone also causes skin depigmentation.
Nevus depigmentosus is a loss of pigment in the skin which can be easily differentiated from vitiligo. Although age factor has not much involvement in the nevus depigmentosus but in about 19% of the cases these are noted at birth. Their size may however grow in proportion to growth of the body.
PUVA (psoralen and UVA) is an ultraviolet light therapy treatment for skin diseases: vitiligo, eczema, psoriasis, graft-versus-host disease, mycosis fungoides, large plaque parapsoriasis, and cutaneous T-cell lymphoma, using the sensitizing effects of the drug psoralen.
Photorejuvenation is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds to the skin. This prompts the skin to heal itself, by creating new cells.
