UV radiation is used in phototherapy, also known as light therapy, to help stop immune system reactions that lead to eczema.

Lifestyle changes

Eczema can be efficiently prevented by adopting certain lifestyle adjustments, such as breathing exercises, yoga, meditation, getting enough sleep, and listening to calming music.

2. Psoriasis

Skin Rashes and Itching

It is a skin condition that accelerates skin cell growth by up to 10 times. Due to this, the skin develops rough red patches that are coated in white scales.

Psoriasis typically affects the knees, elbows, trunk, and scalp. Symptoms include an itchy, scaly rash. Psoriasis typically affects adults. Even young children, though, can become victims.

Causes:

Psoriasis is an autoimmune condition. It is experienced when your immune system overreacts to bacteria or foreign viruses. The T cell, a particular sort of cell, starts to function. The immune system reacts to this. People with a family history of psoriasis are more likely to develop the skin condition.

Treatments:

There are numerous therapies. In order to determine the best course of treatment for you, your doctor will consider factors such as the extent of the rash and the location on your body, as well as your age and general health.

Common treatments:

Moisturizers for dry skin
Steroids
Retinoids creams
Vitamin D creams

Treatments for severe Psoriasis include:

Light Therapy: Skin is exposed to ultraviolet radiation by a physician to stop the proliferation of skin cells.
Retinoids: Their gels, pills, and creams are a class of drugs that belongs to vitamin A.
Anthralin: It is a topical psoriasis medication that lowers cell turnover.
Salicylic Acid: This is a widely used component in shampoos and cosmetics. It eliminates dead skin cells and lessens scaling.

3. Hives (Urticaria)

Red Rashes On Skin

They are bumps on the skin's surface that are red, elevated, and itchy. In most cases, an allergic reaction is to blame.

Causes:

When the skin reacts to an allergen, it causes urticaria in a person. The skin may emit histamine as a result of the allergic reaction. Histamines are self-defense against infections. Histamine causes fluids to build up beneath the skin, which results in inflammation and irritation.

Food and products that triggers allergic reaction:

Medications (antibiotics)
Insect bites
Sun exposure
Intestinal parasites
Scratching
Animal hair
Bacterial infection

Treatment:

Antihistamines: They reduce and obstruct histamines' effects on the skin. This results in reduced inflammation and itching.
Corticosteroids: Hives that remain for a long time or are chronic may require oral corticosteroids or biologic medications. An injection of epinephrine may be necessary for severe cases of hives.
Cyclosporine: Helps in alleviating symptoms in cases of severe unresponsive cases.

4. Vasculitis

Skin Rashes That Itch

An inflammatory response to blood vessels occurs when the body's immune system attacks them by mistake.

Causes:

Although the origin is frequently unknown, this condition may be brought on by an infection or a medication. There are many types of vasculitis, ranging from a modest skin issue to a more serious condition that affects organs such as the kidneys or heart.

Treatment:

It depends on the severity of the condition and which organs of the body have been affected.

Corticosteroids: Inflammation can be reduced by using corticosteroids. It is also possible to take additional antibiotics and immunosuppressive medications like colchicine and cyclosporine to minimize inflammation.
Plasmapheresis: lowers plasma antibody level.
Interferon therapy: to reduce inflammation.

Before taking any of these should be discussed with your dermatologist.
