What is a skin rash?!
A rash is a change of the skin which affects its color, appearance or texture. A rash may be localized in one part of the body, or affect all the skin. Rashes may cause the skin to change color, itch, become warm, bumpy, dry, cracked or blistered, swell and may be painful. The causes, and therefore treatments for rashes, vary widely. Diagnosis must take into account such things as the appearance of the rash, other symptoms, what the patient may have been exposed to, occupation, and occurrence in family members. The diagnosis may confirm any number of conditions. continue reading »

Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than x-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV. It is so named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet.
Ultraviolet (UV) radiation from sunlight can damage DNA, the critical geneticmaterial in every cell of every person. When damaged by UV radiation from sunlight or artificial light sources such as sun lamps and tanning booths,DNA loses its power to control how and when cells grow and divide.Sometimes, this DNA damage leads to the formation of skin cancer.

Who’s At Risk of this kind of skin disease:
Dandruff occurs in 15–20% of the population; seborrheic dermatitis (with redness and flaking) occurs in 3–5%. The problem affects all races, may be a bit worse in men, and starts after puberty (although babies have a version called cradle cap). Seborrheic dermatitis peaks around the age of 40 and then may improve. Severe seborrheic dermatitis is seen frequently in people with Parkinson disease, and other with central nervous system problems, and in those with HIV infection.
