How Does FDA Approved Sunscreen Protect Your Skin?

Understanding Sunscreen

Many people enjoy sunny days. But did you know that the sun's rays can harm your skin? It's true! That's why using sunscreen is so important. An FDA approved sunscreen can help protect your skin from the sun's harmful effects. Let's dive into how it works.

1. What Is SPF?

SPF stands for Sun Protection Factor. It tells you how well a sunscreen can protect your skin from UV rays. For example, SPF 30 blocks about 97% of UVB rays. That's pretty good! But remember, no sunscreen can block 100% of rays.

2. How Does It Work?

So, how does sunscreen keep your skin safe?

“It creates a barrier,” explains Dr. Sunny, a dermatologist. “This barrier reflects or absorbs the sun's rays.”

We can break this down further:

• Physical Blockers: Ingredients like zinc oxide and titanium dioxide sit on your skin. They reflect UV light.
• Chemical Blockers: Ingredients like avobenzone or octisalate absorb UV light. They change UV rays into heat, which is harmless.

3. Types of UV Rays

There are two main types of UV rays: UVA and UVB. Understanding them helps explain why sunscreen is crucial.

• UVA Rays: These rays penetrate deeply. They can cause aging and skin cancer.
• UVB Rays: These rays are the reason you get sunburned. They affect the surface of your skin.

FDA approved sunscreens often protect against both types of rays. Look for “broad-spectrum” on the label.

4. How to Choose the Right Sunscreen

Choosing the right sunscreen can be tricky. Here are some easy tips:

1. Look for an SPF of 30 or higher.
2. Choose “broad-spectrum” for full protection.
3. Pick water-resistant options if you plan to swim.
4. Consider your skin type. If you have sensitive skin, look for mineral-based sunscreens.

5. How to Apply Sunscreen

Applying sunscreen correctly is just as important. Dr. Sunny says, “Most people don’t apply enough.” Here’s how to do it right:

• Apply 15 minutes before going outside.
• Use about an ounce (a shot glass worth) for full body coverage.
• Don’t forget spots like ears, neck, and the back of your hands.
• Reapply every two hours, or after swimming or sweating.

The Bottom Line

FDA approved sunscreen is essential for skin care. It protects against harmful UV rays, keeping your skin healthy. Always choose the right type and apply it correctly!
