No: It will only cause you to burn faster and greater. Use an approved sunscreen with SPF 15 or higher and limit sun exposure and tanning beds as much as possible. Love that lilly white skin! hate that cancer! you will not think you look so good with the doctors have to "whittle you up" in a few years!

Yes: Sunscreens do not completely stop all of the uv rays from getting to the skin. Your melanin will be activated causing your skin to tan. Keep in mind that you don't need to burn to get skin damage from uv sun rays over time.

Possibly: It is a good idea to always follow the expiration dates on medications including skincare. Some active ingredients may breakdown into other/different active molecules over time.

Not anymore.: In the past the two were used interchangeably... But sometimes they weren't... Block should be better than screen, right? Confusing, huh? Well to clear up confusion, the fda recently (6/11) banned the use of the term 'sunblock' and the ban will be enacted in a year. So it's just sunscreen now.

Titanium Dioxide: Titanium is one of the physical sun blocking agents found in certain sunscreens. I recommend the physical blocks (zinc and titanium) because they have a very good safety profile and work very effectively. If you are going to be in the sun - use a minimum of SPF 15 - follow product directions.
