I don't tan pretty. A few minutes in the afternoon sun and skin tans to a shade of grey.
After tremendous research (and trial and error), I highly recommend the following to keep the harmful sun rays at bay
Kiehl's Ultra Light Daily Defense SPF 50
La Roche-Posay's Anthelios AC Anti-Shine Matte Fluid
Don't forget an extra wide brimmed hat!
Woven Floppy Sun Hat
