"1stly - Invisible Moisturizer SPF 40" is using UV filters in a relatively low concentration. Because of this, it might not be able to provide reliable sun protection.
It also works as a moisturizer, so you do not have to use an additional hydrating product.
This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. Here are the exact UV filters in this sunscreen: tinosorb s 5.30% - 8.00%.
This product does not contain known common irritants and is suitable for sensitive skin. We assess the overall irritancy of this sunscreen to be low. For a detailed overview of all potential irritants: click here
