Natural sunscreens only have a few ingredients and consist mainly of water, plant extracts such as aloe vera or cocoa butter. Chemical mineral-based sunscreens also contain titanium dioxide (TiO2) which acts like an invisible shield to repel the solar rays from reaching your skin. The label "Broad Spectrum" indicates that it protects against both UVA and UVB rays - the two forms of ultraviolet light involved in tanning you.
