Topical Treatments

It is a treatment option ideal for the mild form of plaque psoriasis. The treatment is mostly used alone and not in combination with other options. You need to apply the creams/ointment on your directly for getting relief. For severe cases, your doctor combines creams with oral medication or light therapy. So, the treatment options include:

Salicylic Acid

Coal Tar

Coal tar derived from coal reduces the scaling, itching, and inflammation associated with the plaque psoriasis. But, the actual coal tar applied directly on your skin can trigger irritation. It is also messy as it stains your clothes or bedding when it comes in contact. The strong odor can also make you wary of the product. So, you can use OTC (over-the-counter) shampoos, creams or oil containing coal tar. But, it is not advised for pregnant women due to its side effects.

Light Therapy/Phototherapy

Light Therapy/Phototherapy

You can either opt for the simple and easy form of phototherapy with natural sunlight or artificial ultraviolet light to get relief from the problem. Your doctor can suggest it alone or in combination with other medication to get the desired results.

So, it reduces the scaling and inflammation associated with the problem. You need to expose the affected skin to small amounts of sunlight every day. It can improve the plaque psoriasis to an extent. But, you need to maintain caution as overexposure can worsen the symptoms and result in severe skin damage. You need to get the advice from your doctor about the safest method to use natural sunlight for treating a skin disorder.

UVB Phototherapy

It is suggested for mild to moderate plaque psoriasis. Controlled doses of Ultraviolet (UV)-B light from the artificial source can treat skin disorders. UVB phototherapy or broadband UVB can treat single patches or widespread skin patches. It is also effective in treating the condition that is resistant to topical treatments.

Narrow Band UVB Phototherapy

You need the administration for at least two to three times a week until you see improvement in your skin condition. You need to undergo a weekly session to maintain it.

Goeckerman Therapy

In some cases, doctors combine UVB treatment along with coal tar treatment to increase efficiency. It is referred to as Goeckerman therapy. The combination of two therapies offers effective results compared to just one method. It is because using coal tar makes your skin more receptive to ultraviolet B (UVB) light.

PUVA (Psoralen plus ultraviolet A)

It is a technique that makes your skin more responsive to phototherapy. It is a form of photochemotherapy, which uses psoralen (a light-sensitizing medication) before exposing your skin to UVA light. The medication makes your skin more receptive to UVA exposure. So, UVA light penetrates deep into your skin compared to UVB light.

Excimer Laser

Excimer Laser

It is the light therapy option your doctor selects for mild to moderate form of plaque psoriasis. The therapy only treats the affected skin without causing any harm to your healthy skin. During the therapy, your affected skin gets the controlled beam of UVB light. So, it controls the inflammation and scaling associated with the skin problem. You need to undergo less session of excimer laser therapy compared to the traditional phototherapy session. It is because the therapy uses more powerful UVB light.

For severe plaque psoriasis, your doctor can adopt a different approach to manage the condition. In most cases, oral or injected drugs can provide relief. The treatment also known as systematic treatment is effective when other treatment options fail to offer relief. But, the treatment option has severe side effects. So, it is used only for a brief period. It is alternated with other forms of treatment to avoid lasting adverse effects. Here are the options available:

It is an oral medication that can reduce the production of skin cells. The medication is also effective in suppressing inflammation occurring due to the skin disorder. The drugs can also slow down the progression of the condition in some people. But, it is not used for a long period due to its serious side effects.


It is the medication that has similar effects of methotrexate. Irrespective of its effectiveness, it is prescribed only for a short duration of time. The drugs suppress your immune system to manage skin disorder. Like other immunosuppressant drugs, it puts you at risk of health problems like infection, cancer, kidney problem, and high blood pressure. So, the drug is not an ideal choice for long-term therapy or higher doses.


It is the drugs that can alter your immune system and offer relief from the symptoms of plaque psoriasis. The approved drugs can treat mild to severe cases of skin disorder. The injectable drugs often provide relief to people who fail to respond to traditional treatment options or suffer from psoriatic arthritis. Since biologics have a strong effect on the immune system, your doctor prescribes it with caution. To avoid life-threatening infections, your doctor suggests regular screening for different problems, including tuberculosis.
