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.

Is SPF 60 double SPF 30? No! It's only 1% more

SPF 100 = 99%; SPF 60 = 98%; SPF 30 = 97%; SPF 15 = 93%;

Understanding Waterproof and Sweatproof

Water and sweat resistance ratings are a measure of how long the sunscreen remains effective after exposure. It is measured by intervals of 20 minutes submersion and 15 minutes drying. The FDA requires water resistant formulas to provide at least 40 minutes of coverage before reapplication is required. The maximum rating available for creams and lotions is 80 minutes.

At Beyond Coastal, we strive to not only achieve the minimum ratings but exceed them where possible. Our body sunscreens provide 80 minute water and sweat resistance, while our Active Face Stick and Natural Lip and Face formulas provide 40 minutes of resistance.

If you are doing high intensity activity or in the water for prolonged periods of time, always remember to re-apply liberally to ensure maximum protection.
