Why SPF Is the Most Important Skincare Step (and How to Pick One)

If you only do one thing for your skin, make it daily SPF. It's the step that protects every other step. Here's why — and how to pick one you'll actually wear.

Why SPF matters most

UV exposure is the biggest driver of the look of dark spots, dullness and early fine lines. Sunscreen protects the glow you're working for — skip it, and your serums are fighting an uphill battle. (This is about appearance; for medical sun-protection advice, see a professional.)

How to pick a K-beauty SPF

  • SPF 50+ PA++++ for strong daily protection.
  • Lightweight, no white cast — Korean SPFs feel like skincare, so you'll actually reapply.
  • Hydrating finish — bonus glow under makeup or bare.

How to use it

  • Last step of your morning routine, every day (yes, even indoors/cloudy).
  • Reapply through the day when you can.
