Yes. It is important to apply sunscreen both indoor and outdoor

Yes, you should wear SPF indoors or outdoors.. and if you're sitting near windows, or in front of a computer screen or mobile screen , as you're exposing yourself to potentially skin-damaging light so you should definitely wear a screen that even protects ur skin from blue light ,that's why I use ThriveCo's Sunscreen which contains SPF 50 and Hyaluronic Acid too.. not only this Sunscreen protects my skin from harmful UVA/B rays but also keep my skin safe from blue light emitted from smartphones and computers.

If your home has sun facing windows and doors then yes you should use sunscreen at home too. As it's season of too much humidity and sweating occurs too much so use Thriveco sunscreen gel which is non sticky and provide full protection
