What is SPF?

SPF stands for Sun Protection Factor.

It measures the level of protection against UVB rays.

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

For example, SPF 30 means you can stay 30 times longer.

Select SPF based on your skin type and sun exposure.

Higher SPF offers more protection but reapplication is key.

Apply sunscreen 15-30 minutes before sun exposure.

Reapply every two hours or after swimming.

SPF only measures UVB protection, not UVA.

Broad-spectrum products protect against both types.
