Hyperpigmentation is caused by an increase in melanin. Melanin is the natural pigment that gives our skin, hair and eyes their color. A number of factors can trigger an increase in melanin production, but the main ones are sun exposure, hormonal influences, age and skin injuries or inflammation. So very rarely you will get that if you will know your daily dose when being exposed to RLT
I think green therapy is more recommended for hyperpigmentation. The wavelength targets melanocytes, slowing down the production of melanin so that not as much pigmentation reaches the top layers of our skin
@gudemama – Maybe you can suggest red light therapy to your friend. When it comes to sun damage and hypermigmentation, RLt increases the body’s production of collagen and elastin and immune response that helps clear away dead cells and repair damaged ones.
