So, if you’re curious about this innovative skincare technique, read on to discover why phototherapy may be the solution you’ve been searching for.

The Basics Of Phototherapy: What You Need To Know

What is Phototherapy?

Phototherapy is a medical treatment that uses specific wavelengths of light to treat various skin conditions. It involves exposing the affected areas of the skin to controlled doses of ultraviolet (UV) light. The light penetrates the skin and reaches the underlying cells, helping to alleviate symptoms and promote healing.

Types of Phototherapy

1. UVB Phototherapy

UVB phototherapy is one of the most commonly used forms of phototherapy. It uses shortwave ultraviolet light to treat skin conditions such as psoriasis, eczema, and vitiligo. The treatment involves exposing the skin to UVB light for a specific amount of time, gradually increasing the exposure duration as the skin becomes more accustomed to the therapy.

2. PUVA Phototherapy

PUVA, which stands for Psoralen plus Ultraviolet A, is a type of phototherapy that combines the use of medication called psoralen with UVA light exposure. Psoralen makes the skin more sensitive to UVA light, allowing for more effective treatment of conditions such as psoriasis, vitiligo, and eczema. PUVA treatment typically involves taking psoralen orally or applying it topically before the UVA light exposure.

3. Narrowband UVB

Narrowband UVB is a variation of UVB phototherapy that uses a specific range of wavelengths, primarily around 311-312 nanometers. This narrower wavelength range has been found to be particularly effective in treating skin conditions such as psoriasis, eczema, and vitiligo, while minimizing potential side effects. Narrowband UVB offers similar benefits to traditional UVB therapy but requires fewer treatment sessions.

4. Excimer Laser Therapy

Excimer laser therapy is a targeted form of phototherapy that delivers high-intensity UVB light to specific areas of the skin affected by conditions such as psoriasis and vitiligo. This type of therapy can be a suitable option for individuals who have localized patches of affected skin or who have not responded adequately to other forms of treatment. Excimer laser therapy typically requires fewer treatment sessions and offers targeted relief.

Benefits of Phototherapy

1. Treatment of Psoriasis

Phototherapy has proven to be an effective treatment option for psoriasis, a chronic autoimmune disease characterized by itchy, scaly patches of skin. UVB and PUVA phototherapy help slow down the rapid growth of skin cells in psoriasis lesions, reducing inflammation and the severity of symptoms. Regular phototherapy sessions can lead to significant improvements in psoriasis-affected skin, providing relief and improving quality of life.

2. Management of Vitiligo

Vitiligo is a skin condition characterized by the loss of melanin, resulting in white patches or depigmentation on the skin. Phototherapy, particularly with narrowband UVB or PUVA, can help stimulate the production of melanin in the affected areas, leading to repigmentation. While not a cure, phototherapy can help manage vitiligo by reducing the visibility of white patches and enhancing the overall appearance of the skin.

3. Eczema Relief

Individuals with eczema often experience dry, itchy, and inflamed skin. Phototherapy, particularly with UVB light, can help alleviate these symptoms by reducing inflammation and improving the skin’s ability to retain moisture. Regular phototherapy sessions can provide relief from eczema flare-ups and improve overall skin health.

4. Reduction of Itchiness

Itchiness is a common symptom associated with many skin conditions. Phototherapy treatments, especially those using UVB or PUVA, have been shown to effectively reduce itchiness in various skin disorders. By targeting the underlying causes of itchiness, phototherapy offers significant relief and helps individuals regain control over their comfort and well-being.

5. Improvement of Mood Disorders

Skin conditions can significantly impact an individual’s mental and emotional well-being. Phototherapy sessions, particularly those involving UVB light, have been found to have mood-enhancing effects. Exposure to UVB light can stimulate the production of serotonin, a neurotransmitter associated with mood regulation. As a result, phototherapy not only improves physical symptoms but can also have a positive impact on mental health.

Phototherapy Process

1. Initial Consultation

Before starting phototherapy, it is crucial to have an initial consultation with a dermatologist. During this consultation, the dermatologist will assess your skin condition, discuss your medical history, and determine if phototherapy is the right treatment option for you. They will also explain the potential risks and benefits of the treatment and address any concerns or questions you may have.

2. Treatment Plan

Once the decision is made to proceed with phototherapy, the dermatologist will develop a customized treatment plan based on your specific needs and condition. The treatment plan will include the frequency and duration of phototherapy sessions, as well as any additional medications or precautions that may be necessary.

3. Preparing for Phototherapy

Before starting phototherapy, it is essential to prepare your skin properly. This may involve avoiding certain medications or topical treatments that can make your skin more sensitive to light. Your dermatologist will provide specific instructions based on your situation. It is also crucial to protect your eyes during treatment, as UV light can be harmful to the eyes.

4. During Phototherapy Sessions

During phototherapy sessions, you will be positioned in a phototherapy booth or stand in front of a light panel. The affected area of your skin will be exposed to the UV light for the specified duration. It is important to follow the provider’s instructions regarding positioning, clothing, and protective measures to ensure the most effective and safe treatment.

5. Post-Treatment Care

After each phototherapy session, it is essential to take care of your skin properly. This may involve applying moisturizers to hydrate the skin and alleviate any potential dryness or irritation. Additionally, it is important to protect your skin from excessive sunlight, as it can increase the risk of sunburn.

Extended exposure to UV light, especially in high doses, can potentially lead to long-term skin damage. However, when phototherapy is performed under the supervision of a qualified healthcare professional, the risks of long-term damage are minimized. It is crucial to follow the treatment plan and recommendations provided by your dermatologist.

5. Eye Damage

UV light can be harmful to the eyes, and proper eye protection is crucial during phototherapy sessions. Wearing protective goggles or eyewear provided by the provider can minimize the risk of eye damage.

Choosing a Phototherapy Provider

When considering phototherapy, it is important to choose a reputable and experienced phototherapy provider. Here are some factors to consider when making your choice:
