I burn in daylight, so if I'm planning to be out in the sun it's hat with a brim and factor 50.
I don't use any post-shave products. Or pre-shave for that matter.
I’m pretty lucky, I just go brown - I wear a hat and factor 50 when going outside to help prevent exposure, however, I’ve spent many years driving cars that don’t have UV protection in the window glass and didn’t use sunscreen. Not surprisingly, I seem to have the majority of sun related damage on the side of my face that faced the glass.
These days, we are more aware of the dangers of sun exposure. I guess, getting the mix right when using post shave products that help with the skin and also applying factor 50 when going out is key to skin protection.
