The Ultimate Sunscreen Guide: How to Choose & Layer SPF Like a K-Beauty Pro

Why Sunscreen Is the #1 Anti-Aging Product You're Probably Skipping

If there's one step dermatologists and K-beauty experts agree on, it's this: sunscreen is non-negotiable. UV rays are responsible for up to 90% of visible skin aging β€” wrinkles, dark spots, and loss of elasticity. Yet most people either skip SPF or apply it incorrectly.

At La Glow, we believe great skin starts with great protection. Here's everything you need to know about choosing and using sunscreen the right way.

SPF 30 vs. SPF 50: What's the Real Difference?

SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. The difference sounds small, but for daily use β€” especially if you're outdoors β€” SPF 50 gives you a meaningful extra layer of defense. For most skin types, we recommend SPF 50 broad spectrum for daily use.

Chemical vs. Physical Sunscreen

  • Chemical sunscreens (like avobenzone, octinoxate) absorb UV rays and convert them to heat. They tend to be lightweight and invisible on skin.
  • Physical sunscreens (zinc oxide, titanium dioxide) sit on top of skin and reflect UV rays. Great for sensitive skin but can leave a white cast.
  • Hybrid formulas combine both β€” the best of both worlds for everyday wear.

How to Layer Sunscreen in Your Skincare Routine

  1. Cleanser
  2. Toner / Essence
  3. Serum
  4. Moisturizer
  5. Sunscreen (always last in AM routine)
  6. Makeup (optional)

Apply sunscreen 15–20 minutes before sun exposure and reapply every 2 hours if you're outdoors.

Common Sunscreen Mistakes to Avoid

  • ❌ Not using enough β€” you need about a quarter teaspoon for your face alone
  • ❌ Skipping SPF on cloudy days (UV rays penetrate clouds!)
  • ❌ Relying on SPF in foundation β€” it's not enough coverage
  • ❌ Forgetting your neck, ears, and hands
