About this sunscreen
Rilastil Sunsystem MD Fluido SPF 100+ is a very-high-SPF hybrid fluid combining octocrylene and avobenzone with titanium dioxide and the modern filter Tinosorb S for excellent, well-rounded protection. The fluid texture stays lightweight with a matte finish and low white cast, and it performs excellently as a makeup base. It can sting somewhat near the eyes, but the high protection and strong wear give it 81.7/100. A great choice for very high sun exposure that still sits well under makeup.
