Red light therapy, also known as low-level light therapy (LLLT), involves using red to near-infrared light to treat various conditions. Research highlights several benefits and applications of this therapy:

Effects on the Skin and Brain: Red light therapy promotes healing in the skin and brain by influencing cellular functions. It enhances mitochondrial function and has potential benefits for conditions like retinal disease, stroke, and neurodegeneration. Red light therapy is also noted for not causing significant adverse effects at beneficial energy densities (Rojas & Gonzalez-Lima, 2011).

Treatment of Acne: Studies show red light therapy can significantly reduce acne severity without adverse effects, providing a safe alternative to traditional acne treatments (Hörfelt et al., 2009).

Pain and Inflammation Reduction: Red light therapy has been found effective in reducing pain and inflammation in conditions such as spinal cord injuries, by modulating glial responses and reducing neuronal cell death (Hu et al., 2020).

Neurodegenerative Diseases: It's suggested that red light therapy could be explored as a treatment option for neurodegenerative diseases related to dendropathy, like glaucoma and Alzheimer's, by delaying dendritic pruning (Beirne, Różanowska, & Votruba, 2016).

Oncological Safety: Preliminary studies indicate that red light therapy does not promote tumor growth and may be safe for use in patients with existing malignancies, although further research is needed to fully understand its effects on cancer (Myakishev-Rempel et al., 2012).
