what does spf mean

SPF stands for Sun Protection Factor.

Understanding SPF

SPF stands for Sun Protection Factor.

It measures the level of protection against UVB rays.

How SPF Works

SPF indicates how long you can stay in the sun without burning.

For example, SPF 30 means 30 times longer protection.

Choosing the Right SPF

Select an SPF based on your skin type and sun exposure.

Higher SPF offers more protection but isn't a substitute for reapplication.

• Fair skin: SPF 30 or higher
• Medium skin: SPF 15-30
• Dark skin: SPF 15 or higher

Reapplication is Key

Reapply sunscreen every two hours.

More frequent application is needed after swimming or sweating.

Broad Spectrum Protection

Look for 'broad spectrum' on labels.

This means protection against both UVA and UVB rays.
