SPF measures sunscreen protection from UVB rays, the kind that cause sunburn and contribute to skin cancer. SPF does not measure how well a sunscreen will protect from UVA rays, which are also damaging and dangerous. Dermatologists recommend using a SPF15 or SPF30 sunscreen. Higher SPFs don't give much more protection. SPF 30+ reading is good for children.
