SPF: What Does it Mean?

“Don't forget to pack your sunscreen!”

If you are heading to the beach or spending some time in the sun, we bet (at least we hope) you are reaching for your sunscreen before heading outside. But what do we know about sunscreen? Here are some frequently asked questions to keep you informed:

What does sunscreen do?

Sunscreen helps shield your skin from ultraviolet (UV) rays by either scattering the sun's light and reflecting it away from your body, or by absorbing the UV rays before they reach your skin.

What is SPF?

SPF – or Sun Protection Factor – is a measure of a sunscreen's ability to prevent UV rays from harming your skin. Some of you may already know that the recommended sunscreen for all is SPF 15 for adults and SPF 30 for children and seniors.

Who needs to where sunscreen?

Anyone 6 months or older should use sunscreen every day. Children under 6 months should not be exposed to sunlight since their skin is highly sensitive to the ingredients in sunscreen.

Do I need sunscreen if I work inside?

Yes! Even if you work indoors, you should wear sunscreen. Windows generally do not filter out UV rays.
