Oxidative stress caused by the sun’s UVA and UVB rays are the primary cause of premature skin aging and skin hyperpigmentation issues, but recent studies have shown that high-energy visible light, the light we see all around us, also causes oxidative stress to skin and can also contribute to hyperpigmentation.1,2.
