You must know this before using a light therapy mask

Red light is one of the wavelengths of visible light in natural light and is commonly found in our daily lives. It is a non-surgical cosmetic procedure that is non-invasive, utilises a specific wavelength of natural light to activate the body's ability to heal and regenerate itself, and delivers this targeted energy at a higher rate than natural light, without harmful UV rays, so it can be considered highly safe. In a major light therapy study conducted in 2013, researchers from Harvard University and MIT praised light therapy as "non-invasive and almost completely free of side effects".

However, the high safety of light therapy is predicated on the choice of a qualified beauty salon and a red light health and beauty chamber (health and whitening chamber) from a regular manufacturer. And when using it, you need to wear goggles and pay attention to the protection of your eyes. In terms of duration and periodicity of use, users need to follow the advice of a professional beautician or physiotherapist to avoid excessive or overuse.
