Red light therapy for skin repair

By Aimee Jansen5 min read

Red light therapy has been studied in scientific and clinical settings for years because of its potential influence on skin repair (Hamblin, 2017; Salamon, 2025). Wavelengths around 630 to 660 nanometres penetrate the upper layers of the skin and are being investigated for their potential skin-supporting effects (Couturaud et al., 2023; Papageorgiou et al., 2000; Wunsch & Matuschka, 2014). As a result, more and more people are wondering whether they can use this technology on wounds as well.

At Maxi Meilleur we believe in honest, transparent information: we guide you through what red light therapy does from a scientific standpoint, how cosmetic applications differ from medical treatments, and what role an LED mask can realistically play within your skincare routine.

Does red light therapy work for wound healing?

Scientific research shows that red light can have a measurable influence on the repair of skin cells (Hamblin, 2017). In clinical settings, light within specific wavelengths is studied as a supporting element of broader skin treatments (Khoury & Goldman, 2008; Wunsch & Matuschka, 2014). At the same time, it is important to make a nuanced distinction: a cosmetic red light therapy mask is not designed or certified to heal active wounds. For open skin injuries, burns or post-surgical skin, a doctor or dermatologist is always the right point of contact.

Cosmetic red light devices are developed for use on healthy, intact skin and focus on skin radiance and skin comfort. How effective an LED mask truly is depends on the scientific evidence behind the device and the way you use it. Maxi Meilleur deliberately chooses transparency about what a cosmetic light device can and cannot do.

How does red light therapy work on wounds?

Red light therapy projects photons within a specific wavelength onto the skin. These photons are absorbed by the skin and can influence skin processes in a non-invasive way (Hamblin, 2017). Scientific literature examines how this principle can affect the skin at a cellular level (Hamblin, 2017; Salamon, 2025).

Within the cosmetic domain, red light plays a supporting role in a firmer and more even skin radiance and in helping irritated but healthy skin appear calmer (Couturaud et al., 2023; Wunsch & Matuschka, 2014). The different colours in an LED mask each have their own area of application; red light focuses on rejuvenation, while infrared masks penetrate deeper into the skin layers (Wunsch & Matuschka, 2014). For active wounds or damaged skin, we always refer you to a dermatologist or general practitioner.

Benefits of red light therapy on wounds

A cosmetic LED mask is not a treatment for active wounds, but within the right framework red light therapy does offer a number of supporting properties for use on healthy skin.

• Supports a well-cared-for skin radiance: red light is studied in scientific literature in relation to a firmer and more even skin radiance with consistent use (Couturaud et al., 2023; Weiss et al., 2005; Wunsch & Matuschka, 2014).
• Refines skin texture: regular use on healthy skin can contribute to a more even skin structure and a smoother-looking skin surface (Weiss et al., 2005; Wunsch & Matuschka, 2014).
• Non-invasive application: red light therapy works without heat build-up, chemical agents or mechanical irritation, which makes it pleasant for daily use (Salamon, 2025).
• Comfort and ease of use: an LED mask integrates easily into your existing skincare routine, without side effects that disrupt your daily schedule.
• Gentle approach for sensitive skin: because the light works contact-free and UV-free, it is an accessible addition for anyone looking for a skin-friendly routine (Salamon, 2025).

These benefits apply exclusively to use on healthy, intact skin. For wound healing, a doctor or dermatologist is always the right point of contact.
