What does SPF mean? SPF stands for Sun Protection Factor. The number tells
you how long the sun’s UVB rays would take to redden your skin if you
apply the sunscreen exactly as directed compared with the amount of time
without sunscreen. So, if you use an SPF 30 product properly, it would
take you 30 times longer to burn than if you used no sunscreen.
How often you should apply?
Every day! The best practice is to apply 30 minutes before venturing
outside to allow the sunscreen to bind to your skin. Reapply every two
hours of exposure and immediately after swimming or excessive sweating.
Even when it’s cloudy, up to 80 percent of the sun’s UV radiation reaches
the earth. Going unprotected on an overcast day can lead to skin damage.
What level of SPF do I need? If you’re inside most of the day with just
short intervals in the sun, you can use a sunscreen or cosmetic product
with an SPF of 15 or higher. If you spend a lot of time outdoors,
especially when and where the sun is strongest, you need an SPF 30 or
higher, water-resistant sunscreen. More about SPF. No matter the SPF,
reapplication every two hours is key. Sunscreen must also be reapplied
immediately after swimming or sweating.
