1. You can't always trust the claimed SPF - many sunscreens tested fell short of their actual level of protection. Dermatologists recommend using a sunscreen with at least an SPF of 30, and to frequently re-apply the sunscreen while outside.
2. Your sunscreen may only be doing half of its job - "br...oad spectrum" sunscreens protect against both UVB and UVA rays. Unlike UVB rays, which are more prevalent in the summer and between 10 am and 4 pm, UVA rays are always present and they can pass through glass and clouds. UVA rays have a deeper penetration in the skin, and can accelerate skin damage and the chance of melanoma. You should look for "broad spectrum" coverage against both types of rays.
3. "Natural" and mineral sunscreens did not work as well - according to the consumer reports evaluation.
4. You don't have to spend a lot to get excellent sunscreen protection (ratings to follow)
5. Sunscreen doesn't have to be "sticky or stinky"
