Skin Diseases – skin conditions such as psoriasis, eczema, acne and others is probably the most well known cause of skin irritation and itchiness. Below is a breakdown of the most common skin disorders.
a. Psoriasis – is an autoimmune disease that affects the skin. It occurs when the immune system mistakes the skin cells as a pathogen, and sends out faulty signals that speed up the growth cycle of skin cells.
Psoriasis is not contagious.However, psoriasis has been linked to an increased risk of stroke. There are five types of psoriasis: plaque, guttate, inverse, pustular, and erythrodermic.
The most common form, plaque psoriasis, is commonly seen as red and white hues of scaly patches appearing on the top first layer of the skin.
The disorder is a chronic recurring condition that varies in severity from minor localized patches to complete body coverage.
There are many treatments available, but because of its chronic recurring nature, psoriasis is a challenge to treat. Withdrawal of corticosteroids which is a topical steroid cream can aggravate the condition due to the ‘rebound effect’ of corticosteroids. There are natural psoriasis treatments that also help control the disorder. 
b. Eczema – is a skin condition that include dryness and rashes that are identified by redness, swelling of the skin, itching, crusting, flaking, blistering, cracking, oozing, or bleeding. Eczema is believed to be a hereditary allergy that run in families who also have asthma.
An Itchy rash is particularly noticeable on the head and scalp, neck, inside of elbows, behind knees, and buttocks. The cause of eczema is unknown but is presumed to be a combination of genetic and environmental factors.
There is no known cure for eczema; therefore, treatments aim to control the symptoms by reducing inflammation and relieving itching. Corticosteroids are highly effective in controlling or suppressing symptoms in most cases.
Prolonged use of topical corticosteroids is thought to increase the risk of side effects, the most common of which is the skin becoming thin and fragile. Moisturizers and other natural eczema treatments can be used instead for a more long term and holistic approach.
c. Rosacea – is a chronic condition characterized by redness in the face which sometimes results in pimples. There are four types of rosacea that affects adults three types affects the skin and the last one affecting the eyes. If the condition is left untreated it will worsen over time.
Treatment in the form of topical steroids can also aggravate the condition even more. This skin condition typically affect caucasian women but can affect men as well. The disorder can be confused with, and co-exist with acne vulgaris.
Treating rosecea varies depending on severity and subtypes. A subtype-directed approach to treating rosacea patients is recommended to dermatologists. Mild cases are often not treated at all, or are simply covered up with normal cosmetics.
Therapy for the treatment of rosacea is not curative, and is best measured in terms of reduction in the amount of erythema and inflammatory lesions, decrease in the number, duration, and intensity of flares, and concomitant symptoms of itching, burning, and tenderness. The two primary modalities of rosacea treatment are topical and oral antibiotic agents.
