The best I've found - I live in a smallish town - is SPF50. But I've found that the Coppertone Spectra spf 50 is gentle enough that I can use it on my face which is pretty sensitive to some products. I grew up in the South many, many years ago and it took me a long time (and moving to San Franciso in my late 20s) to realize that tan skin isn't only unhealthy, it isn't attractive either. I have a couple of friends my age - mid 50s - who grew up in So. Calif. and their skin has really taken a beating appearance-wise.
