Description
[edit | edit source]
UVR is a non-ionizing radiation and lies between soft x-rays and visible light in the electromagnetic spectrum. It has a wavelength of 10 nm 300/480 nm. The therapeutic part of ultraviolet spectrum are classified by International Commission on Radiation (CIE)[1] on the basis of dominant biological effects displayed by each region as :
UV - A 315 - 400 nm Encourage wound healing
UV - B 280 - 315 nm Skin erythematous region
UV - C 100 - 280 nm Germicidal region
Ultraviolet radiation obeys the law that governs all the radiations, they may reflect, scatter and are absorbed by molecular chromophores. The degree of absorption is generally greater for shorter wavelengths, shorter wavelengths penetrate less deeply. Absorption depends on the thickness of the epidermis and any pigmentation of the skin. Skin thickening due to lesions will result in increased scattering and absorption and thus reduced penetration.

Acne[edit | edit source]
Acne is skin condition which presents pustules, papules and comedomes blocking the hair follicles and sebaceous glands on the face, back and chest.
Modest improvement was observed with sunburn rays (UV-B) and slightly more with the combination of long ultraviolet radiation (UV-A) and UV-B.
Clinical Presentation[edit | edit source]
add text here relating to the clinical presentation of the condition, including pre- and post- intervention assessment measures.
Resources[edit | edit source]
add appropriate resources here, including text links or content demonstrating the intervention or technique
