Exactly What is Skin Psoriasis?
The mission of Skin Psoriasis Organization is providing free information for people who suffer from skin psoriasis.
Skin Psoriasis is a common skin condition causing skin irritation and redness. Most people suffering from skin psoriasis have thick looking red skin with flaky scales which are usually silvery-white in color.
What are the Causes of Skin Psoriasis
Skin Psoriasis is a very common skin condition. Anyone can get SkinPsoriasis, however it most often starts in mid-teen thru mid-30s of age.
Skin Psoriasis is not contiguous and cannot be spread to others.
Skin Psoriasis is often hereditary in nature and passed-down thru the family. Doctors think it may be an auto-immune condition. This occurs when the immune system mistakenly attacks and inflames or destroys healthy body tissue.
Normal skin cells grow deep in the skin and rise to the surface about monthly. When you have psoriasis, this process takes place too fast. Dead skin cells build up on the skin's surface.
The following conditions may start a psoriasis event or make the condition harder to treat:
- Bacteria or viral infections, including strep throat and upper respiratory infections
- Dry air or dry skin
- Injury to the skin, including burns, cuts and insect bites
- Some medicines, including anti-malaria drugs, beta-blockers, and lithium
- Too little sunlight
- Too much sunlight (sunburn)
- Too much alcohol
Psoriasis may be worse in people who have a weak immune system. This may be due to:
- Autoimmune disorders (such as rheumatoid arthritis)
- Cancer chemotherapy
Some people with psoriasis may also have arthritis (psoriatic arthritis).
Symptoms of Skin Psoriasis
Psoriasis can appear suddenly or slowly. Many times, it goes away and then comes back.
The main symptom of skin psoriasis is irritated and flaky red patches of skin. Patches are most often seen on the elbows, knees, and middle of the body. But they can appear anywhere, including on the scalp.
The skin may be:
- Dry and covered with silver, flaky skin (scales)
- Pink-red in color (like the color of salmon)
- Raised and thick
Other symptoms may include:
- Genital sores in males
- Joint pain or aching
- Nail changes, including thick nails, yellow-brown nails, dents or separating of the nail from the skin
- Severe dandruff on the scalp
There are 5 main types of psoriasis of the skin:
- Erythrodermic -- The skin redness is very intense and covers a large area.
- Guttate -- Small, pink-red spots appear on the skin.
- Inverse -- Skin redness and irritation occurs in the armpits, groin, and in between overlapping skin.
- Plaque -- Thick, red patches of skin are covered by flaky, silver-white scales. This is the most common type of psoriasis.
- Pustular -- White blisters are surrounded by red, irritated skin.
Exams and Tests for Skin Psoriasis
Your skin doctor or nurse can very often diagnose this condition by looking at your skin.
Sometimes, a skin biopsy is done to rule out other possible conditions. If you have joint pain, your doctor may order x-rays.
Treatment for Skin Psoriasis
The goal of treatment is to control your symptoms and prevent infection.
Three treatment options are available:
- Skin lotions, ointments, creams, and shampoos. These are called topical treatments.
- Pills or injections that affect the body's immune response, not just the skin. These are called systemic, or body-wide, treatments.
- Phototherapy, which uses light to treat psoriasis.
TREATMENTS USED ON THE SKIN (TOPICAL)
Most of the time, psoriasis is treated with medicines that are placed directly on the skin or scalp. These may include:
- Cortisone creams and ointments
- Creams or ointments that contain coal tar or anthralin
- Creams to remove the scaling (usually salicylic acid or lactic acid)
- Dandruff shampoos (over-the-counter or prescription)
- Prescription medicines containing vitamin D or vitamin A (retinoids)
SYSTEMIC (BODY-WIDE) TREATMENTS
If you have very severe psoriasis, your doctor will likely recommend medicines that suppress the immune system's problems response. These medicines include methotrexate or cyclosporine. Retinoids such as acitretin can also be used.
Newer drugs called biologics are used when other treatments do not work. Biologics approved for psoriasis treatment include:
- Adalimumab (Humira)
- Etanercept (Enbrel)
- Infliximab (Remicade)
Some people may choose to have photo-therapy.
- Phototherapy is a medical treatment in which your skin is carefully exposed to ultraviolet light.
- Phototherapy may be given alone or after you take a drug that makes the skin sensitive to light.
- Phototherapy for psoriasis can be given as ultraviolet A (UVA) or ultraviolet B (UVB) light.
If you have an infection, your doctor will prescribe antibiotics.
AT HOME CARE
Follow these tips at home:
- Taking a daily bath or shower can help your psoriasis. Try not to scrub too hard because this can irritate the skin and trigger an attack.
- Oatmeal baths may be soothing and may help to loosen scales. You can use over-the-counter oatmeal bath products. Or, you can mix 1 cup of oatmeal into a tub of warm water.
- Keeping your skin clean and moist and avoiding your specific psoriasis triggers may help reduce the number of flare-ups.
- Sunlight may help your symptoms go away. Be careful not to get sunburned.
- Relaxation and antistress techniques may be helpful. The link between stress and flares of psoriasis is not well understood, however.
- Limiting the alcoholic beverages you drink may help keep psoriasis from getting worse.
