If there is one product dermatologists agree on, it is sunscreen. It helps prevent sunburn, protects against the UVA rays linked to premature ageing and keeps the rest of your routine from being undone by daily sun exposure. The problem? Many of us grew up with thick, sticky formulas that smelled like the beach and left a chalky film.
Korean sunscreens changed that. Many feel more like a light moisturiser or serum than a traditional sun cream, which is exactly why people actually wear them every day. Here are five worth knowing, plus everything you need to read a Korean sunscreen label with confidence.

Decoding the Label: SPF and PA
SPF
Measures protection against UVB rays, which mainly cause sunburn. SPF 30 filters around 97% of UVB, SPF 50 around 98%—as long as you apply enough.
PA rating
Measures protection against UVA rays, which reach deeper into the skin and contribute to premature ageing. It ranges from PA+ to PA++++; more plus signs mean more UVA protection.
For everyday wear, look for at least SPF 30 and PA+++. If you spend long periods outdoors, SPF 50+ and PA++++ give you extra margin.
Chemical or Mineral Filters?
Chemical (organic) filters absorb UV light and are behind most of the invisible, lightweight Korean formulas. Mineral (physical) filters—zinc oxide and titanium dioxide—are often preferred by very sensitive skin, but can feel thicker and may leave a white cast on deeper skin tones. Hybrid sunscreens combine both.
The best sunscreen is not the one with the highest number—it is the one you enjoy wearing enough to apply generously every single morning.
Our Five Picks, Up Close

MISSHA All Around Safe Block Essence Sun
The budget-friendly staple
A light essence-type sunscreen that is easy to find and easy to apply. A practical choice if you want one no-fuss sunscreen for the whole household.
Good to know: some Korean sunscreens are reformulated for European or US markets, so the filters and protection level can differ between versions. Always check the label of the product you buy.
How Much Sunscreen Is Enough?
Most people apply only a quarter to half of the amount used in SPF testing—which means much lower real-life protection.
The easiest fix is the two-finger rule: squeeze a line of sunscreen along your index and middle fingers, and use it all on your face and neck.
- Apply as the very last step of your morning routine.
- Wear it on cloudy days—UVA passes through clouds and windows.
- Reapply every two hours outdoors, and after swimming or sweating.
- Don’t forget ears, neck and the backs of your hands.
Editor’s tip: stop the pilling
If sunscreen balls up on your skin, the culprit is usually layering too fast. Use fewer, lighter products underneath, wait a minute after moisturiser, and pat sunscreen on instead of rubbing.
Frequently Asked Questions
Can sunscreen replace my moisturiser?
Hydrating formulas like Round Lab’s can be enough for oily skin in summer. Dry skin usually still benefits from a moisturiser underneath—see our best Korean moisturisers.
Do I need sunscreen in winter?
Yes. UVB levels drop in winter, but UVA stays relatively steady all year round.
Is a higher SPF always better?
Not if it means you apply less. A generous layer of SPF 30 protects better than a thin layer of SPF 50.

Start with Beauty of Joseon Relief Sun if you want one sunscreen that suits most skin types. Choose Round Lab if your skin is dry, and Isntree or SKIN1004 if it is oily or you wear makeup. Whatever you pick, wear it every day—consistency is what makes sunscreen work.
