What is Phototherapy?

Phototherapy involves the use of specific wavelengths of light to target various skin conditions. The light emitted by phototherapy devices can be ultraviolet (UV) A or B, visible, or infrared, depending on the condition being treated. Phototherapy can be administered in various forms, including both targeted (hand held devices focussing on problem areas) or systemic (Full body).
They are a form of skin directed therapies that can be used for large areas of skin with no internal derangements.


What is Excimer Laser?

The excimer laser is a type of phototherapy that uses a specific wavelength of UV light to target various skin conditions. The excimer laser emits a high-intensity beam of UV light that is precisely calibrated to target specific skin cells. This laser is commonly used to treat conditions such as:

  1. Psoriasis: The excimer laser can help reduce psoriatic plaques and inflammation
  2. Vitiligo: The excimer laser can help repigment vitiligo patches
  3. Atopic Dermatitis: The excimer laser can help reduce inflammation and itching associated with atopic dermatitis

    4. How does phototherapy differ from sunlight?

    1. Spectrum/ Specificity:

      Phototherapy typically uses narrowband light (specifically ultraviolet B). This range is more effective in treating skin conditions like psoriasis and vitiligo.

      In contrast, sunlight contains a broader spectrum of UV light, including shorter wavelengths that may cause skin damage or pigmentation

    2. Intensity: Controlled emission of UV light, which can be adjusted to meet individual patient’s needs. This is not seen in sunlight, which varies in intensity throughout the day, season and location
    3. Duration: Phototherapy typically involves short treatment sessions, ranging from a few minutes to 30 minutes. In contrast, sunlight exposure can be prolonged, leading to increased risks of skin damage

Conditions Treated with Phototherapy and Excimer Laser

  1. Psoriasis: Phototherapy, including excimer laser, can help reduce psoriatic plaques and inflammation
  2. Vitiligo: Phototherapy, including excimer laser, can help repigment vitiligo patches
  3. Atopic Dermatitis: Phototherapy, including excimer laser, can help reduce inflammation and itching associated with atopic dermatitis
  4. Acne: Blue light phototherapy can help reduce acne-causing bacteria and inflammation
  5. Pain and Inflammation: Infrared phototherapy can help reduce pain and inflammation in conditions such as arthritis and fibromyalgia

Benefits of Phototherapy and Excimer Laser

  1. Non-Invasive: Phototherapy and excimer laser are non-invasive treatments that do not require surgery or injections
  2. Targeted Treatment: Phototherapy and excimer laser can target specific skin cells and conditions, reducing the risk of side effects
  3. Minimally Painful: Phototherapy and excimer laser treatments are generally minimally painful and well-tolerated
  4. Quick Recovery: Phototherapy and excimer laser treatments typically require minimal downtime, allowing patients to resume their daily activities quickly

Conclusion

Phototherapy and excimer laser are highly effective treatments for various skin conditions. By understanding the mechanisms and benefits of these treatments, patients can make informed decisions about their skincare options. Whether you’re struggling with psoriasis, vitiligo, or acne, phototherapy and excimer laser can provide a safe and effective solution. Consult with a healthcare professional or dermatologist to determine if phototherapy or excimer laser is right for you.
