What is Blue Light Treatment?

Also known as photodynamic therapy, blue light therapy is a type of light treatment used to treat damaged or diseased skin. Medications called photosensitizing agents are used along with specific wavelengths of blue light to destroy abnormal skin cells. The surrounding healthy tissue is left unharmed.

What Does Blue Light Therapy Treat?

There are several applications for blue light therapy. It is frequently used to prevent skin cancer and treat precancerous and cancerous skin growths. Actinic keratoses are pre-cancer types that develop on the skin from years of sun exposure. It appears as rough, scaly patches on the skin that are light, dark tan, red, white, or flesh-toned in color. Blue light treatment is optimal for anyone with multiple patches since they can all be treated simultaneously.

In addition to treating and preventing skin cancer, blue light treatment is also used to treat sunspots, sun damage, and rosacea. It has also become a popular treatment for those who suffer from acne and want to stop using traditional topical medications and treatments.

How Does a Blue Light Treatment Session Work?

Blue light treatment sessions consist of three steps:

  1. The photosensitizing agent is applied to the skin
  2. The medication is absorbed into the skin
  3. The blue light is applied

When the photosensitizing agent is applied to the skin, it makes certain types of skin tissue more susceptible to the absorption of light wavelengths. Once applied, it takes time to absorb. This process can take a few hours, depending on the treated area. When the treated skin is exposed to blue light, it causes a reaction and destroys the targeted skin tissue. Only the skin that absorbed the medication is affected.
