Introduction

Living with psoriasis can be difficult. Those scaly, red patches over the skin can be quite uncomfortable. Many different forms of psoriasis can mess with someone’s quality of life, so getting good treatments is quite important. There are so many techniques available today, but laser treatment has turned out to be one of the most focused therapies.

Laser therapy involves pointing light at the affected skin to minimize inflammation, slow down the rate at which skin cells divide, and help restore the appearance and texture of the skin in the affected area. These are easier to give since laser therapy is only administered to specific areas of the body, unlike other treatments that are given all over the body and thus have many side effects. It has become particularly favored among consumers with mild to moderate psoriasis or for spot treatment.

This type of therapy has further been enhanced through the excimer laser and the pulsed dye laser. They include personalized treatment plans and offer hope to individuals who can be treated after other conventional methods have failed to work for them.

What Is Laser Treatment for Psoriasis?

Red, itchy, scaly skin causes discomfort and embarrassment in people with psoriasis. Treatment options include steroid or other medicated creams, oral medications, and light therapy. While these treatments are effective, medications can have side effects, and light therapy needs a regimen of three sessions per week for two to three months, followed by maintenance therapy.

Today, there is an additional option for treating psoriasis, for example, excimer lasers, which deliver laser light to specific areas of the skin. This treatment employs intense, focused doses of laser light to control mild to moderate psoriasis without damaging the surrounding healthy skin. Targeted laser therapy is comparable in effectiveness to traditional light therapy but works in fewer sessions with stronger light doses that penetrate deeper into the affected skin. The handheld laser wands are also effective for treating psoriasis in difficult-to-reach areas, such as the elbows, knees, palms, soles, and scalp.

Psoriasis Laser Treatment: How It Works?

Psoriasis laser therapy is a non-systemic treatment that involves the administration of light at the affected area in a patient with a skin disorder. Doctors use focused laser beams to treat skin conditions by lowering inflammation and skin cell multiplication to restore psoriasis-affected areas. Here is how it works:

1. Types of Lasers Used-

  • Excimer Laser: This treatment remains the standard laser therapy for patients with psoriasis conditions. It produces a particular wavelength of ultraviolet B (UVB) radiation (308 nm), which impacts only the psoriatic plaques. The UVB light decreases the rate of the overgrowth of the skin cells and inflammation.

  • Pulsed Dye Laser (PDL): This laser aims at the vessels that feed the psoriatic plaques. It does this by eradicating the blood vessels that cause redness and inflammation in the areas that are being treated.

2. Treatment Process-

  • Targeted Application: The laser treatment penetrates infected tissue zones while maintaining healthy skin. It also minimizes the occurrence of side effects and guarantees an ideal treatment.

  • Session Duration: They may be completed within 10 to 30 minutes, depending on the size of an area and the number of affected sessions.

  • Treatment Schedule: Most patients need several visits, ideally two to three sessions weekly for several weeks, to observe the improvements.

3. Functioning-

  • Reduction of Inflammation: The laser light inhibits the immune cells in the skin, hence treating inflammation and redness.

  • Slowing Skin Cell Growth: UVB light can reach the skin’s surface and interfere with the accelerated skin cell division common with psoriasis.

  • Improvement in Plaque: After some time, the affected skin becomes less scaly and itchy, resulting in healthy and clean skin.

What You Should Know Before Starting Laser Treatment?

Laser treatment for psoriasis can yield dramatic results in some individuals, but this therapy may not be suitable for everyone. A thorough health history and examination are important to determine if someone is a good candidate before starting treatment. Avoid laser treatments if you have:

  • Lupus (autoimmune disease affecting tissues) or scleroderma (chronic connective tissue disease).

  • Sun sensitivity.

  • Xeroderma pigmentosum (an inherited disease causing sensitivity to sunlight).

  • Risks of skin cancer.

  • A condition that necessitates taking medications that increase sun sensitivity.

Ideal Candidates: Laser therapy is most effective for individuals with:

  • Mild to moderate psoriasis.

  • Psoriasis is localized in particular zones, which are difficult to treat (elbows, knees, scalp).

  • To some extent, poor response to topical preparations or other forms of treatment.

What Patient Needs to Know About Treatment:

  • Sessions: Each session lasts between 10 and 30 minutes. The frequency of sessions differs; however, changes can occur after 4 to 10 sessions.

  • Localized Treatment: Scratching is done only on the affected skin to avoid damaging healthy skin.

Costs and Insurance: Laser therapy may be expensive, and insurance coverage is rather partial. Check with your provider and insurer regarding the expenses that apply to it.

What Are the Risks of Laser Treatments for Psoriasis?

Laser therapy is usually safe, but some people have reported side effects after treatment, including:

  • Temporary Redness, Itching, Burning, and Stinging: These are common reactions where the treated area may become red, itchy, or have a burning or stinging sensation shortly after the procedure.

  • Blistering: Small blisters can form on the treated skin, similar to what might happen after a sunburn. These blisters are usually temporary and heal within a few days. Proper aftercare can help minimize discomfort and prevent infection.

  • Purple-Colored Spots (Purpura) on the Skin: These are small, purple spots that can appear on the skin due to minor bleeding under the skin.

  • Darkening or Lightening of the Skin (Hyperpigmentation or Hypopigmentation): The treated skin may become darker (hyperpigmentation) or lighter (hypopigmentation) than the surrounding skin.

  • Scarring: In rare cases, the treated area might develop scars. Proper treatment and following post-procedure instructions can help reduce the risk of scarring.

What Are the Side Effects of Laser Treatments for Psoriasis?

Some of the common side effects of laser treatment of psoriasis are listed below-

  • Redness and Irritation - The treated skin may look red or feel sensitive, like it has been sunburned.

  • Blistering - Small vesicles may develop on the treated site, especially if a person is exposed to high levels of light.

  • Peeling - The skin will form scabs as it heals, which is all part of the response to the therapy.

  • Itching - Itching is the most common side effect of treatment, but only mild itching is observed in some patients.

  • Dryness - Skin in the treatment area may peel and may be managed by applying a moisturizer.

  • Rare or Serious Reactions - Some of the skin conditions include hyperpigmentation or hypopigmentation. The treated skin may become darker and form patches compared to the skin adjacent to the treated area, or it may become lighter and also form patches compared to the skin adjacent to the treated area.

  • Infection - In the worst-case scenario, an open blister or sore can lead to skin infection, but such incidences are rare.

  • Worsening of Symptoms - At times, laser therapy has been seen to worsen psoriasis or even cause it to flare up.

  • Burns - It can lead to insularity during treatment and give superficial burns.

Conclusion

People with psoriasis experience ongoing pain and itch from scaly skin patches that reduce their ability to perform regular daily tasks. Patients with this condition experience periods of active disease and periods of relief as everyday stressors and infections make symptoms worse. The excimer laser therapy joins other standard treatments such as creams, light therapy, and systemic medications to help people better manage their psoriatic symptoms. Each type of psoriasis presents unique challenges and requires tailored management strategies to control symptoms effectively.
