UV rays are everywhere, even when we don't see the sun. They don't just cause tanning or dark spots—they speed up skin aging, cause redness, sunburn, and, in severe cases, can even lead to serious skin conditions.

That's why sunscreen is a must-have in our daily skincare routine. It helps protect our skin from harmful UV damage, prevents sunburn, and keeps our skin healthy. But do we really understand sunscreen? Let's go through five essential sun protection tips that will help us choose the right sunscreen and use it effectively!

1. The Golden Rule of Sunscreen Application

Many people assume that sunscreen works the moment we apply it, but timing is everything!

For the best protection, we should apply sunscreen 15 to 30 minutes before heading out. This allows our skin to absorb it properly and ensures that the protective layer adheres well to the skin. Skipping this step could mean we're not getting full protection from the sun!

2. How to Choose the Right SPF?

SPF (Sun Protection Factor) measures how well a sunscreen protects against UVB rays, which cause sunburn. The number represents how much longer our skin can resist sunburn compared to unprotected skin.

For example, SPF 30 means our skin can withstand UVB rays 30 times longer than without sunscreen. A higher SPF means longer protection, but it doesn't mean we should apply it less often.

So, how do we choose the right SPF?

• Outdoor activities (beach, hiking, sports): Use SPF 50+ for stronger protection.

• Daily use (walking, commuting, working indoors): SPF 30 is usually enough.

Higher SPF sunscreens often contain more active ingredients, which may feel heavier on the skin. So if we're indoors most of the time, using SPF 30 can balance protection and comfort.

3. What Is the PA Rating and Why Is It Important?

UVB causes sunburn, but UVA is the real skin-ager. It go through deep into our skin, breaking down collagen and elastin, leading to wrinkles, sagging, and pigmentation over time.

The PA rating (Protection Grade of UVA) tells us how well a sunscreen defends against UVA rays:

• PA+ → Some UVA protection

• PA++ → Moderate UVA protection

• PA+++ → High UVA protection

• PA++++ → Very high UVA protection

In Japan and other Asian countries, PA ratings are commonly used, while Western brands often label UVA protection as “Broad Spectrum”. When choosing sunscreen, we should look for both high SPF and a good PA rating to ensure complete UV protection.

4. Physical vs. Chemical Sunscreen: Which One to Choose?

There are two main types of sunscreen: physical (mineral) and chemical. Each has its pros and cons, so choosing the right one depends on our skin type and preference.

Physical Sunscreen (Mineral Sunscreen)

• Forms a protective layer on the skin and reflects UV rays.

• Doesn't get absorbed into the skin, making it less likely to cause irritation or breakouts.

• Great for sensitive skin but tends to be thicker and may leave a white cast.

Chemical Sunscreen

• Absorbs UV rays and neutralizes them before they can harm the skin.

• Lighter texture, easy to apply, and absorbs quickly.

• May cause irritation in sensitive skin due to its active ingredients.

If we have sensitive skin, physical sunscreen is the better choice. If we prefer lightweight and non-greasy formulas, chemical sunscreen may be more comfortable.

5. Do We Need Sunscreen on Cloudy or Rainy Days?

Absolutely! Just because we don't see the sun doesn't mean UV rays aren't there.

UVA rays can go through clouds and even windows, meaning they can damage our skin even when we're indoors or during bad weather. That's why daily sunscreen is a must, regardless of the season or weather.

If we're outdoors for long periods, it's also important to reapply sunscreen every 1-2 hours to maintain protection.

Final Thoughts: Make Sunscreen a Daily Habit!

Sunscreen isn't just for sunny days—it's a year-round essential for healthy skin. By choosing the right SPF and PA, applying it correctly, and reapplying when needed, we can protect our skin from premature aging and sun damage.
