Wearing sunscreen indoors is a matter of personal preference. While indoor lighting and electronic devices emit low levels of UV radiation, they are not a significant source of skin damage. However, if you have specific concerns or conditions that require protection from indoor UV exposure, you may choose to wear sunscreen. When considering sunscreen, it's important to be aware of the ingredients. Sunscreens contain chemical or physical (mineral) active ingredients. Chemical sunscreens contain carbon-containing molecules that absorb light, such as oxybenzone, octinoxate, and avobenzone
. On the other hand, physical sunscreens sit on top of the skin and reflect the sun's rays, and their main active ingredients are titanium dioxide and zinc oxide
. Some studies have raised concerns about the systemic absorption of certain chemical sunscreen ingredients, so if you prefer to use sunscreen indoors, you may want to consider a physical sunscreen with titanium dioxide or zinc oxide as the active ingredients
. It's also important to look for broad-spectrum protection and consider any specific skin sensitivities or allergies when choosing a sunscreen
