can blue light actually cause hyperpigmentation? According to stunning new research in the Journal of Skin Pharmacology, researchers cited that compared with UV, blue light produced darker hyperpigmentation that actually lasted longer! They also found that blue light produces excessive generation of reactive oxygen and nitrogen species. Lastly, they found that blue light can exert indirect effects on the body by disrupting its normal circadian rhythm. This, in turn, can negatively affect your skin’s nightly repair process. • • • • • • #angelskin #bluelight #hyperpigmentation #nycesthetician #blackesthetician #fypシ
