SPF stands for 'Sun Protection Factor' and the number shows how long a sunscreen can help protect your skin from UVB rays compared to not wearing any. For instance, SPF 50 means you may stay in the sun 50 times longer without burning. However, actual protection depends on how much you apply, your skin type, and activity level.

• Higher SPF offers more UVB protection.
• Remember, no sunscreen blocks 100% of rays.
• It's still important to reapply and use other sun protection like hats and shade.

Choosing the right SPF depends on your needs and how much sun exposure you expect.

It's generally recommended to reapply sunscreen every two hours, especially if you're outdoors for extended periods. If you're swimming or sweating, look for water-resistant options and reapply after towel drying or heavy sweating.

• Even water-resistant products need to be reapplied after 80 minutes of swimming or sweating.
• Apply generously to all exposed skin for best coverage.

Keeping sunscreen handy makes it easier to stay protected throughout the day.

Many sunscreens are formulated for both face and body, but some are designed specifically for one area. Facial sunscreens often have lighter textures and may be less likely to clog pores. Body sunscreens might feel heavier or have different finishes.

• Check the label to see if it's suitable for both areas.
• Those with sensitive or acne-prone skin may prefer products labeled 'for face.'

Using the right product can help you stay comfortable and protected, no matter where you apply it.

If you plan to be outdoors, swimming, or exercising, a water- and sweat-resistant sunscreen can be a smart choice. These formulas help maintain protection even when you're moving or getting wet.

• Check for 'water-resistant' or 'sport' on the label.
• Look for broad-spectrum protection against UVA and UVB rays.
• Remember, you still need to reapply after swimming, sweating, or towel-drying.

Choosing the right sunscreen helps keep your skin protected during all your activities.

To help your sunscreen last and work as intended, store it in a cool, dry place away from direct sunlight and heat. High temperatures can break down active ingredients and reduce effectiveness.

• Avoid leaving sunscreen in hot cars or under the sun for long periods.
• Keep the cap tightly closed to prevent spills and contamination.

Proper storage helps make sure your sunscreen stays ready for whenever you need it.
