High Energy Visible Light (HEVIS Light) is all around us. It’s part of the light we can see. It’s been around for as long as UV rays, but while much has been written about their effect on skin, the molecular and visible effect of HEV Light on skin is a more recent discovery. Research proves that HEVIS light influences skin condition and can cause skin to photoage (age prematurely as a result of sun exposure). In this article we examine the effects HEVIS light has on skin, put it into context alongside UVA and UVB rays and consider how best to protect skin from photoaging.
