Yes, you can trust sunscreen if you use it correctly and choose the right product. Sunscreen is a crucial tool for protecting your skin from the harmful effects of the sun's ultraviolet (UV) radiation.
Here's a breakdown of why and how to trust sunscreen:
-
Importance of Sunscreen: Sunscreen helps prevent sunburn, premature aging of the skin, and skin cancer.
-
Choosing the Right Sunscreen:
- SPF (Sun Protection Factor): The Cancer Council recommends using an SPF 50 or SPF 50+ sunscreen. SPF indicates how well a sunscreen protects you from UVB rays, which cause sunburn. Higher SPF offers more protection.
- Broad Spectrum: Make sure the sunscreen is labeled "broad spectrum." This means it protects against both UVA and UVB rays. UVA rays contribute to skin aging and also increase the risk of skin cancer.
- Water Resistance: Choose a water-resistant sunscreen, especially if you'll be swimming or sweating. Remember to reapply it regularly, as "water resistant" doesn't mean waterproof.
- TGA Approval: In Australia, look for sunscreens that are TGA (Therapeutic Goods Administration) approved. This ensures they meet specific safety and effectiveness standards.
-
Proper Application:
- Apply Generously: Most people don't apply enough sunscreen. Use about one ounce (a shot glass full) to cover your entire body.
- Apply 20 Minutes Before Sun Exposure: This allows the sunscreen to bind to your skin.
- Reapply Every Two Hours: Reapply sunscreen every two hours, or more often if you are swimming or sweating.
- Don't Forget Often-Missed Areas: Apply to your ears, neck, back of your hands, and tops of your feet.
-
Checking the Expiry Date: Sunscreens have expiry dates. While using expired sunscreen won't necessarily harm you, it may not be as effective in protecting you from UV radiation. It's best to use sunscreen before its expiration date.
-
Limitations of Sunscreen: Sunscreen is not a complete shield. It should be used in conjunction with other sun protection measures, such as:
- Seeking shade, especially during peak sun hours (usually 10 AM to 4 PM).
- Wearing protective clothing, such as long sleeves, pants, and a wide-brimmed hat.
- Wearing sunglasses to protect your eyes.
In summary, sunscreen is a trustworthy and vital tool for sun protection when used correctly. Choose a broad-spectrum, water-resistant SPF 50+ sunscreen, apply it generously and frequently, and combine it with other sun-safe practices for optimal protection.
