It happened almost overnight. One day, the Beauty of Joseon Relief Sun: Rice + Probiotics was a niche K-beauty secret shared in Discord servers and Reddit threads, and the next, it was basically the only thing on your TikTok feed. It’s rare for a skincare product to achieve "it-girl" status and actually keep it for years. Usually, the hype dies down once people realize the texture is weird or it pills under makeup. But this one stuck.
Why? Because for a long time, sunscreen sucked. It was thick, smelled like a public pool, and left everyone looking like a Victorian ghost. Beauty of Joseon (BoJ) changed that narrative by leaning into traditional Korean herbal medicine—Hanbang—and modern chemical filters. If you’ve been hunting for the daily relief sunscreen Beauty of Joseon offers, you’ve likely noticed it feels more like a moisturizer than a traditional SPF. That’s the hook. But there is a lot of nuance people miss when they just click "buy" on a random Amazon listing.
The Hanbang Philosophy Meets Modern SPF 50+
The core of this formula isn't just about blocking UV rays. It’s about the 30% rice extract and grain fermented extracts. Rice has been a staple in Korean skincare since the Joseon Dynasty—hence the name. Historically, women in the royal court used rice bran water (called mi-gam-su) to brighten and soften their skin. It’s rich in amino acids and minerals. Honestly, it’s kinda cool to see 14th-century beauty standards being validated by modern dermatological labs.
The probiotics part is where it gets technical. We aren't talking about the stuff in your yogurt. These are fermented extracts that help reinforce the skin's natural moisture barrier. When your barrier is healthy, your skin doesn't freak out as much when exposed to environmental stressors.
Is the Protection Actually Real?
Let’s address the elephant in the room. A few years ago, the "Great SPF Purge" happened where several Korean sunscreens were pulled from shelves because their lab-tested SPF didn't match the label. It caused a massive trust issue in the community.
Beauty of Joseon dodged that bullet by being incredibly transparent. They’ve had their SPF ratings verified by separate labs in both Korea and Spain. The results consistently come back at SPF 50.7 and PA++++. They use four modern chemical filters: Uvinul A Plus, Uvinul T 150, Tinosorb M, and Iscotrizinol. These aren't the old-school filters like oxybenzone that people worry about; these are photostable, meaning they don’t break down as quickly when the sun hits them.

The Texture: Why Everyone Is Obsessed
If you hate the feeling of stuff on your face, this is probably your holy grail. It’s a lightweight, creamy fluid. It doesn't have that "greasy" slip. Instead, it sinks in and leaves a slight glow—what people call the "glass skin" effect.
- It doesn't sting your eyes. This is huge. Most Western chemical sunscreens use avobenzone, which feels like acid if it migrates into your tear ducts.
- No white cast. Since it uses modern chemical filters instead of zinc oxide or titanium dioxide, it goes on clear. Even on deep skin tones, it vanishes.
- It’s fragrance-free. No "fake coconut" or "medicinal" scent here.
But—and there’s always a but—it might be too moisturizing for some. If you have extremely oily skin and live in a humid climate like Florida or Singapore, this might feel a bit heavy by lunchtime. You might want to skip your morning moisturizer and just use this as a 2-in-1.
How to Spot a Fake (The Amazon Problem)
Because this product is so viral, the market is flooded with counterfeits. It’s a major problem. Buying the daily relief sunscreen Beauty of Joseon makes from an unverified third-party seller is risky. Fakes often have a different scent, a grainier texture, or worse, they offer zero sun protection.
Check the packaging. Real BoJ boxes have a specific matte texture and a QR code system for verification. The crimp at the top of the tube should be neat. Honestly, just buy from authorized retailers like Olive Young, YesStyle, or the official Beauty of Joseon website. Saving five dollars isn't worth a second-degree sunburn.

Decoding the Ingredients List
If you look at the back of the tube, you'll see a lot of long names. Here’s the breakdown of what actually matters in the formula:
Niacinamide is high up on the list. This is the Swiss Army knife of skincare. It helps with pore size, uneven skin tone, and oil regulation. It’s one of the reasons people feel like their skin looks better after wearing this for a week.
Glycerin and Adenosine are also in the mix. Glycerin is a humectant that pulls water into the skin, while Adenosine is known for its skin-soothing and anti-aging properties.
Then you have the fermented stuff: Lactobacillus/Rice Ferment, Saccharum Officinarum (Sugarcane) Extract, and Monascus/Rice Ferment. These are the ingredients that make the texture so silky. They soften the skin’s surface without needing heavy silicones.
Common Misconceptions and Limitations
One thing people get wrong is thinking this is a "natural" sunscreen because of the rice and probiotics. It’s not. It’s a sophisticated chemical sunscreen. If your skin only tolerates mineral filters (Zinc/Titanium), this might cause a reaction, although it's generally formulated for sensitive skin.

Another thing? It’s not water-resistant.
Do not wear this to the beach. Do not wear this for a 10-mile run in the sun. This is a lifestyle sunscreen. It’s designed for the office, for running errands, for brunch, or for a walk in the park. If you sweat heavily or go swimming, it will slide right off your face. For high-intensity outdoor activity, you need something labeled "Water Resistant" or "Sport."
Real-World Application Tips
To get the actual SPF 50 rating, you have to use enough. The "two-finger rule" is the standard. Apply two strips of sunscreen down your index and middle fingers. It seems like a lot, but this formula is so thin that it spreads and absorbs much faster than you’d expect.
Wait about 10 minutes before applying makeup. This gives the "film-formers" in the sunscreen time to set. If you go straight in with foundation, you’re just mixing the products together and diluting your protection.
If you have dry skin, you’ll love this over your usual cream. If you’re oily, try using a hydrating toner or serum followed immediately by the BoJ sunscreen. It provides enough occlusion to lock in moisture without the extra weight of a heavy cream.
Actionable Steps for Better Protection
- Verify your source: If you bought your tube from a random eBay or unverified Amazon seller and it smells like glue or feels gritty, toss it. Use the "Athe" app or the QR code on the box to check authenticity.
- Layering matters: If you use Vitamin C in the morning (which you should), apply it before the Beauty of Joseon sunscreen. The antioxidants in Vitamin C work synergistically with the SPF to neutralize free radicals from UV exposure.
- Don't forget the neck: The skin on your neck is thinner and ages faster than your face. Since this sunscreen feels like a lotion, it’s much easier to blend down your neck and chest without it feeling gross on your collar.
- Reapplication: Since this isn't a "sport" formula, it does degrade. If you are sitting near a window all day, try to reapply once in the afternoon. If you have makeup on, a sun stick from the same brand (the Matte Sun Stick) works well for touch-ups without smudging your concealer.
- Storage: Keep the tube out of your hot car. Heat can destabilize the chemical filters and the probiotics, making the formula less effective. Keep it in a cool, dry place.
The hype around the daily relief sunscreen Beauty of Joseon created is actually backed by solid formulation and independent testing. It’s one of the few products that lives up to the "invisible" promise while keeping the skin hydrated. Just remember it's a daily-wear product, not a survival tool for a tropical vacation, and always source it from a reputable vendor to ensure you're getting the actual SPF 50 protection you paid for.
