The beauty trend that uses near-infrared light waves has surged in popularity – but can you achieve results at home?
If you are interested in beauty trends and self-care, you’ve probably encountered red light therapy (RLT). Formally known as photobiomodulation, doctors first discovered that red and near-infrared light wavelengths sped hair regrowth in the late sixties. Later studies found it boosted wound healing. Since then, it has gradually entered the esthetics field, initially gaining traction as an in-office tool for post-operative recovery in plastic surgery patients, explains Dr Prem Tripathi, a facial plastic surgeon based in Alamo, California.
By the mid 2010s, RLT devices emerged for use at home. These have surged in popularity as a non-invasive way to purportedly smooth wrinkles, heal acne and scars, improve skin tone and boost hair growth.
