Sunlight has several adverse health effects when overexposed to the skin. Apart from sunburns and skin cancers, sunlight can also lead to loss of collagen, melasma, and photoaging. Sunlight is composed of several different wavelengths of light including ultraviolet B (UVB), ultraviolet A (UVA), and visible blue light. Much of the focus is typically on UVB as SPF predominantly refers to protection against UVB. However, protection against UVA and blue light overexposure are vital as these wavelengths are responsible for photoaging and dyspigmentation. This article summarizes the effects of UVA and blue light, and strategies to protect from them.
