Very sheer sunscreen.
Size: 3 Fl Oz (Pack of 3)
As always, the company does a good job of providing sun protection without white goopy stuff lingering on the skin. Can be worn under makeup.

Perfect sunscreen for adult men... and others as well
Size: 3 Fl Oz (Pack of 3), Size: 3 Fl Oz (Pack of 3)
I live in the southwest where you have to use sunscreen on your face every day or it will impact your skin. No questions about that. I use this sunscreen every day as it's light weight enough that my face doesn't look greasy or shiny at all, it flat out works (when I miss a spot I know it) and it reasonably priced. I have no idea if this works in combination with anything else like foundation or make-up but I say for any guys out there that want a simple everyday face sunscreen you cannot go wrong with this one. Buy it, use it, protect your skin for years to come.
