How Phototherapy works

The science of phototherapy, which has been around for about 100 years, uses light to improve the health of the body. As far back as two thousand years ago, the ancient Greeks had a center for studying the effects of different colored lights on the body. Even the ancient Egyptians, who promoted health by focusing sunlight through colored glass on certain areas of the body, understood this concept.

Phototherapy is a treatment that uses specific wavelengths of light to improve or treat certain medical or skin conditions. The light triggers biological reactions in the body or skin. ☀️

Different types of light can affect the skin, cells, mood, sleep cycles, and other functions depending on the wavelength and method used.

The word comes from:

• “photo” = light

• “therapy” = treatment or support

Simple explanation:

Phototherapy = healing with light.

Common types of phototherapy:

1. UV phototherapy (ultraviolet light)

Used by dermatologists to treat skin diseases such as:

• Psoriasis

• Eczema

• Vitiligo

Types include:

• UVB therapy

• PUVA therapy (psoralen + UVA light)

These slow excessive skin cell growth and reduce inflammation.

2. LED / red-light therapy

Often used in wellness clinics and spas. It uses red or near-infrared light to:

• support skin healing

• reduce inflammation

• stimulate collagen

• help with muscle recovery

Examples include devices like LifeWave X39 patch, which claims to stimulate light signals in the body (photobiomodulation).

3. Blue-light phototherapy

Commonly used for:

• acne treatment

• killing bacteria that cause breakouts.

4. Neonatal phototherapy

Hospitals use blue light to treat newborn babies with Neonatal jaundice by helping the body break down excess bilirubin.

Different colors and wavelengths of light cause different biological effects in the body.

✅ Improved cellular regeneration and energy

✅ Improved energy, stamina and fitness performance

✅ Anti-inflammatory effects

✅ Skin repair

✅ Improved sleep and mood

✅ Reduced stress and anxiety

✅ Faster wound healing

✅ Faster recovery

One commonly discussed concept is that certain wavelengths may support mitochondrial activity — the part of cells involved in energy production.

You can think of phototherapy as:

using light as a signal to encourage certain responses in the body.

Phototherapy patches

Some wellness products, including patch-based systems, are designed to reflect or interact with body heat/light rather than emit powered light like a lamp or laser. These products are marketed as a non-invasive wellness approach.

The exact mechanism and scientific evidence can vary significantly between products, so it’s important to review manufacturer information
