Unlocking The Benefits Of Phototherapy For Skin Conditions

What is Phototherapy?

Phototherapy is a medical treatment that uses light to manage various skin conditions. It involves exposing the affected area of the skin to specific wavelengths of light, which can help alleviate symptoms and promote healing. This non-invasive procedure has been widely used for decades and has proven to be effective in treating a range of skin conditions.


Phototherapy, also known as light therapy, is a treatment method that utilizes light to treat skin disorders. It involves exposing the affected skin to a specific type of light, such as ultraviolet (UV) rays or visible light, for a predetermined amount of time. The light can be emitted from specialized devices like lamps or lasers, depending on the specific condition being targeted.

Types of Phototherapy

There are several types of phototherapy that are commonly used to treat various skin conditions:

  1. Narrowband UVB: This type of phototherapy uses a specific narrow range of UVB light that is most effective in treating conditions like psoriasis, eczema, and vitiligo.

  2. PUVA Therapy: PUVA therapy combines UVA light exposure with a medication called psoralen, which can sensitize the skin to the effects of the light. It is mainly used for psoriasis, vitiligo, and some forms of dermatitis.

  3. Excimer Laser: This targeted phototherapy uses a laser to deliver a high-intensity beam of UVB light to small affected areas of the skin, such as in vitiligo or psoriasis.

  4. Blue Light Therapy: Blue light therapy utilizes a specific wavelength of blue light to target and kill the bacteria responsible for acne breakouts.

  5. Red Light Therapy: Red light therapy involves using a specific wavelength of red light to stimulate collagen production, reduce inflammation, and promote healing.

Each type of phototherapy serves a specific purpose and is chosen based on the individual’s skin condition and its severity.

How does Phototherapy work?

Phototherapy works by exposing the skin to specific wavelengths of light, which can penetrate deep into the skin layers and affect various cells and processes. Depending on the type of phototherapy used, the mechanisms of action may vary.

In the case of narrowband UVB and PUVA therapy, the light exposure can help slow down the rapid growth of skin cells in conditions like psoriasis and eczema. This helps reduce inflammation, redness, and itching associated with these conditions.

Excimer laser therapy delivers a targeted dose of UVB light, which stimulates the production of melanocytes in vitiligo-affected areas, leading to repigmentation of the skin.

For acne treatment, blue light therapy can kill the bacteria responsible for acne breakouts by targeting the porphyrins within the bacteria. Red light therapy, on the other hand, stimulates collagen production and promotes overall skin healing.
