Beauty of Joseon Relief Sun: Rice + Probiotics is the Korean sunscreen that escaped the specialist sites and landed in actual British bathrooms. It is SPF50+ PA++++, it looks like a moisturiser, and it is the reason a lot of people finally stopped treating sunscreen as optional. This is a wear review, not a love letter.

What it actually is
A chemical daily sunscreen with rice extract and a probiotic ferment. The rice and probiotics are the brand story. It sells because of the vehicle: a serum-gel that spreads thin and does not sit as a white paste. Not a zinc cream, not a swimming SPF. Office-to-weekend face wear.
Sibling formulas exist (aqua-fresh, other finishes). The one people mean by "the Joseon SPF" is still Rice + Probiotics, 50ml, yellow carton.
Finish and feel
On most skin it goes on like a slightly silky essence, then dries to a natural glow. Not greasy if you used the right amount. A bit shiny if you used too much, or if you are already oily.
Dry and normal skin tend to love it. It can replace a heavy morning moisturiser in summer, which is why it shows up in dry-skin K-SPF conversations.
Oily skin is split. Some people wear it as-is. Others blot and powder by late morning. If you need mattifying as the default, look at Korean sunscreen for oily skin or Missha Soft Finish instead of forcing this one to be something it is not. Our wider SPF for oily skin list includes this as the Korean pick with that caveat.
It does not sting most eyes. It can sting if you put it too close to the lash line. That is user error more than a unique defect.
White cast
None, on the skin tones this formula is famous for serving. That is the chemical/hybrid advantage. If you still see grey, you have used too much and not blended at the hairline and jaw.
Deeper skin tones generally do better with this than with zinc sticks. If a Korean SPF is going to fail you on cast, it is usually a mineral one, not Relief Sun.
Under makeup
This is the main reason it went mainstream.
Apply after whatever serum and moisturiser you still need. Wait 60 to 90 seconds. Then primer or foundation. If you go in wet-on-wet, it pills. If your moisturiser is a thick occlusive, it pills. If you rub foundation in circles like you are polishing a car, it pills.
Pressed in, after a wait, it is one of the better Korean SPFs under makeup. Powder on top is fine. A silicone-heavy primer on top of a silicone-heavy base is how people get little rolls on the cheeks.
Amount still matters. Two fingers of Relief Sun, then makeup. A pea-sized "I do not want to ruin my foundation" smear is not the labelled SPF50+. See how to apply Korean sunscreen.
What it is not
It is not the most moisturising option: Round Lab wins if you want SPF that behaves like cream. Stylevana prices make it a budget K-SPF; Cult Beauty is the convenience tax. If you flare at botanicals, read Korean sunscreen for sensitive skin before buying three tubes. Pleasant texture is how you get daily SPF done. It is not extra protection beyond what you apply.
UK stockists and price
Typical price: £12–£18 for 50ml, depending on the seller and whether you are paying for next-day UK postage.
Stylevana / YesStyle: usually the low end of that range. Factor in shipping thresholds and delivery time.
Cult Beauty: the straightforward UK buy. Returns are easier. Price is higher than the Asian retailers.
Boots / Lookfantastic / Beauty Bay: stock comes and goes as K-beauty ranges expand. Worth a search; not the most reliable everyday source.
Buy from known retailers. Relief Sun is popular enough to attract grey-market listings.
How it fits a routine
Morning: cleanse if you need to, treatments, moisturiser if you still feel dry, then Relief Sun as the last skincare step. That is the same layering order as any SPF.
Night: it needs a proper take-off. Double cleanse. A single foaming wash often leaves a film.
Outdoors: reapply. Over makeup, that is sticks, powders and sprays, with honest limits. Relief Sun in a tube is still the best first application; it is messy as a 3pm top-up on a full face of base.
It sits in the same "elegant daily SPF" idea as the rest of Korean skincare. You do not need the whole Joseon line. More UK products: that guide.
The verdict
Relief Sun is popular because it is easy to wear. The rice and probiotics are the story; the filters and the texture are why people finish the tube. No white cast, makeup-friendly, cheap enough on Stylevana, easy enough on Cult Beauty. Buy it if you want one Korean SPF and a dewy-natural finish. Skip it if you need a matte factory finish or a swimming SPF. For most people asking "which Korean sunscreen?", this is still the 2026 answer.
FAQs
Does Beauty of Joseon Relief Sun leave a white cast?
No. It is a chemical formula and it should disappear. A grey film usually means too much product or incomplete blending at the edges.
Can you wear Beauty of Joseon Relief Sun under makeup?
Yes, and that is its best trick. Wait a minute after applying, do not overdo moisturiser underneath, and press foundation on rather than rubbing.
Where can I buy Beauty of Joseon sunscreen in the UK?
Stylevana and YesStyle for price, Cult Beauty for UK delivery. Check Boots and Lookfantastic; stock is inconsistent.
Is Relief Sun good for oily skin?
Sometimes. It is a glowy formula. If you get shiny fast, pair it with powder or choose a more mattifying K-SPF.
How much does Beauty of Joseon Relief Sun cost?
Usually £12–£18 for 50ml in the UK, depending on the retailer.
