Overview of Treating Skin Diseases and Rejuvenating Skin using Light Sources
Aachal A. Sharma, D. Haranath
The electromagnetic spectrum of sunlight, which includes infrared (IR, 52–55%), visible (VIS, 42–43%), and ultraviolet radiation (UV, 3-5%), is a naturally occurring source of light. Out of all these radiations, UV radiations with specific wavelengths have been shown to have clinically important biological effects that are both efficient and safe for human skin. UV radiation exposure primarily aids in the formation of vitamin D synthesis and has the potential to suppress immunological response, making it a more acceptable wavelength range for the diagnosis and treatment of various skin dermatoses. While comparing natural sunlight which contains less percentage of UV radiation with broadband range artificial UV therapy is an efficient, reliable, affordable, and, nonsurgical therapeutic option available for skin dermatoses. Recent investigations and literature reviews demonstrate that various types of phototherapies such as UVB narrowband, PUVA, etc. have incompatible efficacy toward the management of dermatoses that often depend upon the action, for instance, and absorption spectra of the biological molecule (chromophores) contained in the human skin. We attempt to categorize human skin conditions by their symptoms, topological facts, and dosimetry prescribed for the cures by the minimal erythemal dosage (MED) of phototherapy recommended by the dermatologist. Descriptive analysis of types of therapies carried out on narrowband (311 ± 2 nm) and broadband (295-315 nm) ultraviolent radiation B (UVB) therapy, light-sensitive organic drug (Psoralen) in combination with UVA (PUVA) therapy and laser therapy. This review article aims at the development in the field of dermatology by reviewing historical data, therapeutic options available, a detailed understanding of skin dermatoses, and the availability of light sources for the clearance of various skin dermatoses.
