What is 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 you can stay 30 times longer.

Choosing the Right SPF

Select SPF based on your skin type and sun exposure.

Higher SPF offers more protection but reapplication is key.

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

Application Tips

Apply sunscreen 15-30 minutes before sun exposure.

Reapply every two hours or after swimming.

Limitations of SPF

SPF only measures UVB protection, not UVA.

Broad-spectrum products protect against both types.
