Why Is Korean Sunscreen So Different? PA++++, Feather-Light Textures and the Filters Behind Them
"For years I treated sunscreen as a beach product: thick, white, slightly greasy, and only for holidays. Korean sunscreen changed that, and not because of some secret ingredient. It changed it because in Korea sunscreen is treated as the last step of skincare, something you wear every morning, so it has to feel good enough to wear every morning. Here is what actually makes Korean SPF different, what PA++++ means, why the filters are less exotic than you'd think, and the three I'd start with."
The short answer: what makes Korean sunscreen different
Three things. Texture first: Korean sunscreens are formulated to feel like a moisturizer or serum, because they are designed for daily wear under makeup, not for the beach. Clear UVA labelling: the PA rating tells you how strong the UVA protection is at a glance. Modern filters: they rely on newer, photostable UV filters that are approved in Europe but not in the US, which is why Korean SPF often feels so much lighter than American sunscreen. European brands use many of the same filters; the real difference is the formulation priority.
SPF
Protection against UVB, the rays that cause sunburn. SPF50+ is the highest category on both Korean and European labels.
PA rating
The Korean and Japanese measure of UVA protection, the rays behind photoageing and dark spots. PA++++ is the top grade.
The EU UVA logo
Europe's equivalent: a "UVA" in a circle means UVA protection is at least one third of the SPF. Different system, same goal.

Texture First: Why Korean Sunscreen Feels Like Skincare
If sunscreen is the last step of a daily routine, it has to behave like skincare: absorb quickly, leave no white cast, sit invisibly under foundation and add some hydration of its own. These two are the clearest examples of a sunscreen that doubles as a moisturizer.
Beauty of Joseon Relief Sun: Rice + Probiotics SPF50+ PA++++ (50ml)
SPF50+ PA++++ protection from modern filters, in a base of 30% rice extract and a grain probiotic complex with niacinamide. It spreads like a light cream, sinks in within a minute and leaves a soft, healthy glow rather than shine. On my combination skin it worked as my morning moisturizer on all but the driest winter days, and it never pilled under foundation. Fragrance-free, vegan, dermatologically-tested and pregnancy-friendly.
Best for: sensitive, dry and normal skin; anyone who hates heavy or chalky sunscreen; daily wear under makeup.Less suited to: very oily skin that wants a matte finish; the dewy glow can read as shine by afternoon.
Editor’s tip: Let it set for a minute before foundation. If it feels too rich in summer, the Aqua-Fresh version in the same range is lighter.

Round LAB Birch Moisturizing Sunscreen UVLock SPF 45+ (50ml)
Birch sap from Inje in Korea and hyaluronic acid give this sunscreen the feel of a hydrating lotion, with the same family of modern UV filters as the Relief Sun. It is the best choice here if you want to skip a separate morning moisturizer. It applies invisibly and leaves skin comfortable rather than shiny. Fragrance-free, vegan, dermatologically-tested, pregnancy-friendly and made with clean ingredients.
Best for: dry, normal, sensitive and combination skin; minimal morning routines; cold, dry months.Less suited to: anyone who wants the highest SPF number; it is SPF45+ rather than 50+, which is still high protection for daily wear.
Editor’s tip: On minimal mornings, cleanse, apply a hydrating toner, then this. Two steps and you're done.

The Sun Serum: Korea's Lightest Sunscreen Format
The sun serum is a category Korean brands have made their own: a fluid, almost watery texture with full SPF50+ protection. It is the format that converts people with oily skin who have given up on sunscreen.
SKIN1004 Madagascar Centella Hyalu-cica Water-Fit Sun Serum SPF50+ PA++++ (50ml)
Hyaluronic acid and Madagascar centella asiatica hydrate and soothe while modern filters provide high UVB and UVA protection. It is the lightest sunscreen I've tested: no stickiness, no white cast, and nothing to wait for before makeup. It also works well for reapplication over a light base. Fragrance-free, vegan, dermatologically-tested, pregnancy-friendly and made with clean ingredients.
Best for: combination, normal, sensitive and dehydrated skin; anyone who dislikes the feel of sunscreen; warm days and humid weather.Less suited to: very dry skin in winter as the only morning step; use a moisturizer underneath.
Editor’s tip: Because it's so light, it's easy to under-apply. Measure two full finger-lengths for face and neck, and apply in two thin layers.

The UV Filters Behind Korean Sunscreen, Explained
There is no secret Korean filter. The three sunscreens above rely on a family of modern, photostable filters that are all approved under EU cosmetics rules: diethylamino hydroxybenzoyl hexyl benzoate (a UVA filter), ethylhexyl triazone and diethylhexyl butamido triazone (UVB filters) and methylene bis-benzotriazolyl tetramethylbutylphenol (a broad-spectrum filter). Several were developed by European chemical companies. What they are not is approved in the US, which is why American sunscreens often feel heavier and why Korean SPF built its reputation there. The honest takeaway for European shoppers: the protection is comparable to good European sunscreen; the difference you feel is the formulation.
| Sunscreen | Protection | Texture & finish | Best for | Less suited to |
|---|---|---|---|---|
| Beauty of Joseon Relief Sun | SPF50+ PA++++ | Light cream, dewy glow | Dry, normal, sensitive; under makeup | Very oily skin wanting matte |
| Round LAB Birch Sunscreen | SPF45+ | Hydrating lotion, comfortable finish | Dry and normal skin; 2-in-1 mornings | Anyone set on SPF50+ |
| SKIN1004 Water-Fit Sun Serum | SPF50+ PA++++ | Watery serum, fresh dewy | Combination, normal, sensitive | Very dry winter skin on its own |
All three are fragrance-free, vegan, dermatologically-tested and pregnancy-friendly.
How to use sunscreen so it actually protects you
The SPF on the label is measured at a generous amount. Most people apply far less, which is the biggest reason sunscreen underperforms.
Use enough
About two finger-lengths for face and neck, applied as the very last step of your morning routine, before makeup.
Reapply outdoors
Every two hours when you're outside, and after sweating or swimming. A stick or serum makes reapplying over makeup easier.
Every day, all year
UVA passes through clouds and window glass, and snow reflects UV back at your face. Winter mornings count too.

Your Korean Sunscreen Questions, Answered
PA ratings, filters, legality in Europe and daily wear.
Is Korean sunscreen better than European sunscreen?
Not in protection: both rely on many of the same modern filters approved in the EU. Where Korean sunscreen usually wins is texture. It is formulated to feel like skincare and sit invisibly under makeup, which makes it easier to wear every day, and the sunscreen you wear daily is the one that protects you.
What does PA++++ mean?
PA is the Korean and Japanese rating for UVA protection, the rays linked to photoageing and dark spots. It runs from PA+ to PA++++, with PA++++ the highest grade. European sunscreens show UVA protection differently, with a UVA logo in a circle.
Are Korean sunscreens safe and legal in Europe?
Sunscreens sold in Europe must use UV filters approved under EU cosmetics rules. The filters in the three sunscreens featured here are all on that approved list. As with any cosmetic, patch-test if your skin is very reactive.
Do I need sunscreen in winter or on cloudy days?
Yes. UVA levels stay significant all year and pass through cloud and glass, and snow reflects a large share of UV back up at your face, especially at altitude. A daily SPF is the single most effective habit for preventing dark spots and premature ageing.
Can my sunscreen replace my moisturizer?
For many people, yes, on most days. Moisturizing sunscreens like the Round LAB Birch Sunscreen or Beauty of Joseon Relief Sun hydrate well enough for normal and combination skin. Very dry skin, or any skin in a cold, dry winter, usually still needs a moisturizer underneath.
