Choose Broad Spectrum Protection
While all sunscreens protect against UVB rays, which are linked to causing skin cancer, the broad spectrum sunscreens protect your skin against both UVB and UVA rays. UVA rays are known for causing premature aging and skin cancer. Sunscreens that are labeled broad spectrum had to pass specific tests to carry this label. If you see a sunscreen that isn’t labeled broad spectrum you’ll see that it says it only prevents sunburn, not protection against skin cancer.
Sun Protection Factor (SPF)
You’ll want to make sure your sunscreen is labeled with a minimum of 30 SPF. This number is the level in which the sunscreen protects you from UVB rays. While no sunscreen can complete you completely, the higher option of SPF 50 is approximately 98% protection and SPF 100 is 99% protection. You’ll find that any sunscreen that’s labeled SPF 15 or lower must have a warning label stating that it only protects against sunburn, not skin cancer.
