Beauty of Joseon Relief Sun: Rice + Probiotics SPF 50+ PA++++ Review
The Beauty of Joseon Relief Sun: Rice + Probiotics became one of the most talked-about Korean sunscreens of 2024–2025 — and the conversation has not stopped. With SPF 50+ PA++++, a probiotic-enriched formula, rice bran extract, and a texture that disappears into skin without white cast or greasiness, it set a new standard for what a daily Korean sunscreen could feel like. Here is the full review after extended testing across skin types and conditions.

Texture and Application Experience
The Relief Sun dispenses as a lightweight, slightly fluid lotion — somewhere between a serum and a standard moisturizer in viscosity. It spreads easily with fingertips and blends to near-invisibility within 30–45 seconds of application. There is no initial whitening, no tackiness after absorption, and no pill-up when applied over skincare layers.
The finish is the key selling point: not matte, not dewy, but a skin-like “your skin but better” result. On fair to medium skin tones, the finish is essentially invisible — the SPF just disappears. On medium-deep to deep skin tones, a very mild brightening effect may be visible, though it is far less pronounced than mineral sunscreens or older chemical filter formulas.
How much to use: For adequate SPF protection, apply a generous amount — about half a teaspoon (2.5ml) for the face. Most people underapply sunscreen by 50–70%, which halves the effective SPF. The Relief Sun’s lightweight texture makes generous application easy without discomfort.
Filter Technology: Why This Formula Works So Well
Beauty of Joseon uses next-generation UV filters not available in US-approved sunscreens — a key reason why Korean sunscreens consistently outperform their Western equivalents in texture and elegance:
- Tinosorb S (Bemotrizinol): Broad-spectrum UV filter covering UVB and long UVA; photostable; allows thinner, lighter formulas
- Tinosorb M (Bisoctrizole): Micro-pigment filter covering UVB and UVA; contributes to the cosmetically elegant finish
- Uvinul A Plus (Diethylamino Hydroxybenzoyl Hexyl Benzoate): Long UVA specialist filter; enhances UVA coverage beyond what avobenzone achieves
This combination delivers more comprehensive UV protection with lighter textures than traditional chemical filter systems — which is why the Relief Sun achieves SPF 50+ PA++++ without feeling like sunscreen at all.
Skincare Ingredients: What the Rice and Probiotics Do
Rice bran extract: A traditional Korean and Japanese skin brightener rich in ferulic acid, vitamin E, and phytic acid. It provides antioxidant protection, mild brightening, and a skin-softening effect that contributes to the comfortable after-feel.
Lactobacillus ferment (probiotics): Fermented probiotic filtrate that supports the skin microbiome, reduces inflammation, and strengthens barrier function. This is an increasingly studied ingredient in dermatology for its role in reducing skin reactivity and rosacea-like symptoms.
Niacinamide: Present at a functional concentration for pore-minimizing and brightening — a natural complement to the rice brightening ingredients.
Performance Testing
Dry skin: Excellent. The formula provides enough hydration for dry skin throughout a full work day without the need for a separate moisturizer on low-maintenance days. Finish remains comfortable for 6–8 hours.
Oily skin: Very good. The non-greasy finish and absence of heavy emollients keeps breakthrough shine minimal. Slight sebum absorption at 5–6 hours is normal — blotting or setting powder extends wear. Better performance than most Korean sunscreens for oily skin.
Sensitive/rosacea skin: Outstanding. Fragrance-free, alcohol-free, probiotic-containing formula is one of the most well-tolerated sunscreens for reactive skin in this price range. Multiple sensitive skin testers wore it 4+ weeks with zero reactions.
Under makeup: Excellent base. Sets semi-matte, does not migrate foundation, and does not interfere with powder products. One of the most makeup-compatible sunscreens tested in 2025–2026.
Beauty of Joseon Relief Sun vs Competitors
| Product | SPF | Finish | Best Skin Type | Price Range |
|---|---|---|---|---|
| BoJ Relief Sun | 50+ PA++++ | Natural / skin-like | All types | $$ |
| ISNTREE Watery Sun Gel | 50+ PA++++ | Dewy | Dry / combination | $$ |

Verdict
The Beauty of Joseon Relief Sun: Rice + Probiotics earns its reputation. It is not a perfect sunscreen for every situation — deeper skin tones may notice slight brightening, and those wanting SPF in a matte finish may prefer EltaMD UV Clear — but for the broadest range of daily use cases, it is among the best-performing Korean sunscreens available at its price point.
Rating: 4.8/5 — A near-perfect daily sunscreen for fair-to-medium skin tones. One of the top Korean SPF recommendations for 2026.

Frequently Asked Questions
Q: Does Beauty of Joseon Relief Sun leave a white cast?
A: On fair to medium skin (approximately Fitzpatrick I–III), virtually no white cast. On medium-deep to deep skin (Fitzpatrick IV–VI), a slight brightening effect may be visible — most deep-skin users report it is significantly less than other sunscreens but still present. The TIRTIR Milk Sun Tinted (available in 17 shades) is a better option for deeper skin tones that want zero cast.
Q: Can I use Beauty of Joseon Relief Sun without moisturizer?
A: For normal-to-dry skin on low-maintenance mornings, yes — the formula provides enough hydration to stand alone. For oily skin or very dry skin needing significant barrier support, use a lightweight moisturizer underneath for best results.
Q: Is Beauty of Joseon Relief Sun reef-safe?
A: No — it uses chemical UV filters, not mineral (zinc oxide or titanium dioxide). It is not reef-safe under Hawaii’s mineral-only sunscreen standards. For reef-safe alternatives, seek mineral Korean sunscreens like Purito Comfy Water Sun Block.
