COVERAGE: Understanding SPF

SPF is a measure of a sunscreen’s ability to protect against UVB rays, and only UVB rays. Currently, there is no ratings system to show the effectiveness of blocking UVA rays; thus allowing high SPF numbers to give a false sense of protection.

At Beyond Coastal, our sunscreen ratings reflect the exact data that we get back from testing. Our SPF is the maximum protection we can provide in our formulas without increasing the proportion of active chemicals to potentially harmful levels.

A good rule of thumb, is to always wear at least SPF 15 and apply liberally to all exposed skin. We often don’t apply as much sunscreen as is necessary to provide maximum protection. However, don’t be fooled into thinking that that a higher number, means significantly more protection. SPF 60 is not twice as strong as SPF 30, in fact it is only 1% more effective at blocking UVB rays.
