photobiomodulation for atopic eczema

Atopic eczema in adults often progresses in cycles, alternating between periods of remission and more uncomfortable phases. Redness, itching, and the sensation of fragile skin—day-to-day life can become a burden. In this context, photobiomodulation—often associated with certain forms of LED and red-light phototherapy—is gaining attention as a gentle way to support the skin.

What can we expect from this type of light therapy? Results are possible, but they are part of a gradual process in which each session plays a role.

Understanding the Mechanisms of Atopic Eczema

Atopic eczema is caused by a compromised skin barrier. The skin becomes more permeable, loses moisture, and reacts more strongly to its environment, which promotes inflammation.

This manifests itself as:

  • red patches of varying sizes
  • persistent itching
  • dry, sensitive skin
  • more pronounced reactions to external stimuli

These conditions evolve over time. Approaches such as photobiomodulation or certain forms of phototherapy are part of a strategy for the gradual management of symptoms.

Photobiomodulation, Phototherapy, and Light Therapy: A Better Understanding of the Differences

Photobiomodulation is a specific therapy based on the use of LEDs, particularly red and near-infrared light.

Light therapy uses broad-spectrum white light, which is primarily perceived by the eyes. Its purpose is different.

Phototherapy encompasses all techniques that use light for therapeutic purposes. Photobiomodulation is a targeted form of phototherapy.

We can distinguish between:

  • light therapy, which works through visual perception
  • phototherapy, which encompasses several light-based treatments
  • photobiomodulation, which uses LEDs and red light to produce a localized effect on the skin

This clarification provides a better understanding of the expected effects of each approach.

How does red light affect cells?

Photobiomodulation relies on LEDs that emit red or infrared light. This light penetrates the skin and interacts with the cells.

The desired effect is based on gently stimulating their activity. This is not an aggressive treatment, but rather a way to support cellular function.

For atopic eczema, this red light therapy may help:

  • regulate skin inflammation
  • improve the cellular environment
  • support collagen production
  • promote more supple and resilient skin

Each session acts as a repeated signal. It is this repetition that allows an effect to take hold over time.

What are the effects on itching and redness?

Itching is often the main source of discomfort. It creates a vicious cycle in which irritation and scratching make the redness worse.

With regular sessions of photobiomodulation using LEDs and red light, certain effects are frequently observed:

  • a gradual soothing effect: the itching becomes less intense
  • reduced redness: the inflammation appears less noticeable
  • improved skin comfort: the skin feels softer and less sensitive

This effect does not take hold immediately. It develops over the course of the sessions, as part of an ongoing process.

A gradual improvement in the skin barrier

The skin barrier plays a key role in eczema. When it is compromised, the skin becomes more vulnerable.

Photobiomodulation, such as LED and red light therapy, can help maintain this balance. Its effect on cells and collagen helps improve skin quality.

Over the course of the sessions, certain changes can be observed:

  • less dry skin
  • a softer texture
  • greater resistance to external stressors

This process takes place gradually. Consistency in your sessions is key to maintaining this effect.

What results can you expect based on how long you use it?

The results of photobiomodulation depend on many factors: skin sensitivity, severity of symptoms, and consistency of treatment sessions.

The First Sessions

A mild effect may occur. The skin feels slightly more soothed, and the itching may be less noticeable at times.

After several weeks

Redness gradually subsides. Skin comfort improves, and the skin appears less reactive.

In the long term

The skin’s functions become more balanced. Episodes of inflammation seem less frequent, and daily life feels more comfortable.

Each person reacts differently to this type of treatment. The effects can vary from person to person.

Incorporating photobiomodulation into a tailored routine

Photobiomodulation is part of a holistic approach. It does not replace daily habits, but rather complements them.

To optimize results:

  • Frequency of sessions: several sessions per week at the start
  • Target areas: areas prone to eczema
  • Duration of sessions: a few minutes, repeated regularly

Some devices make it possibleto use this phototherapy at home, with designs that are easy to use. This ease of use encourages regular use, which is key to achieving long-lasting results.

A Step-by-Step Approach to Living Better with Eczema

Photobiomodulation, such as red light and LED therapy, is a gentle approach. It is not intended as an immediate solution, but rather as a long-term support.

The expected results remain modest:

  • a soothing effect on itching
  • a reduction in redness
  • improved comfort and skin quality
  • skin that's more resilient in everyday life

This type of treatment calls for a more gradual approach. When used in a targeted manner, light becomes a tool to support the skin without causing it any stress.

Over the course of the sessions, this approach can help you better understand skin reactions and find a more balanced way to manage your eczema.
