These are two of the most talked-about Korean sunscreens for a reason: both promise the thing every sunscreen shopper actually wants — real protection that doesn't feel like sunscreen. But they're formulated differently enough that the "better" one genuinely depends on your skin, not just which one is trending.
Quick answer: Beauty of Joseon's Relief Sun: Rice + Probiotics is a fragrance-free, fully chemical (organic-filter) sunscreen with SPF50+ PA++++, built around rice extract and probiotic-derived ingredients for a hydrating, barrier-supporting finish. COSRX's Aloe Soothing Sun Cream is SPF50+ PA+++, uses a hybrid of chemical filters plus titanium dioxide, contains added fragrance, and leans on a high concentration of aloe extract for a calming, lightweight finish. For fragrance-sensitive skin, Beauty of Joseon is the safer default; for oily skin wanting a slightly more mattifying, aloe-forward finish and less concerned about fragrance, COSRX is a reasonable pick — though its added fragrance is worth checking against your own sensitivity first.
Who this comparison is for
This is for people deciding between these two specific, popular Korean sunscreens. It's a formula-based comparison, not medical advice, and it isn't a claim that either product prevents all sun damage on its own — sunscreen works best alongside shade, protective clothing, and reapplication. If you have known fragrance allergies, active acne, or are pregnant or breastfeeding, check the specific ingredient concerns noted below and consult a dermatologist if you're unsure which filters are appropriate for you.
What Beauty of Joseon Relief Sun: Rice + Probiotics offers
This is a lightweight, fully chemical (organic-filter) sunscreen rated SPF50+ PA++++. Its UV filters — including Ethylhexyl Triazone, Diethylamino Hydroxybenzoyl Hexyl Benzoate, and Methylene Bis-Benzotriazolyl Tetramethylbutylphenol — are newer-generation organic filters not commonly found in US-market sunscreens, and the formula contains no titanium dioxide or other mineral filter. It's fragrance-free, formulated with 30% rice extract along with several fermented and probiotic-derived ingredients (aspergillus ferment, rice ferment filtrate, soybean ferment extract) intended to support the skin barrier and add hydration. It's widely described as absorbing without a white cast or greasy residue, with a silky, dewy finish, and is commonly recommended for dry or sensitive skin, though its lightweight texture also suits combination and oily skin reasonably well.
What COSRX Aloe Soothing Sun Cream offers
This sunscreen is rated SPF50+ PA+++ — one PA tier lower than Beauty of Joseon's rating, meaning somewhat less certified UVA protection on paper. It uses a hybrid filter system: chemical filters (including octinoxate, ensulizole, amiloxate, and Tinosorb S) combined with titanium dioxide as a mineral filter. Its standout ingredient is a high concentration of Aloe Arborescens leaf extract, a different, more concentrated aloe species than the common Aloe barbadensis used in most after-sun gels, intended to give the formula a calming, hydrating finish that feels less like typical sunscreen. Unlike Beauty of Joseon's formula, this one contains added fragrance, along with several recognized fragrance allergens (including linalool, limonene, geraniol, and citronellol) listed in its ingredients — worth checking closely if you have known fragrance sensitivity.

Which one fits your skin
- Choose Beauty of Joseon if: you have fragrance-sensitive or reactive skin, want the higher PA++++ rating, or prefer a fully organic-filter formula without titanium dioxide.
- Choose COSRX if: your skin tolerates fragrance well, you like a more aloe-forward, calming finish, and you're comfortable with a hybrid chemical-mineral filter system.
- Skip COSRX if: you have a known fragrance allergy — its formula lists several recognized fragrance allergens that Beauty of Joseon's fragrance-free formula avoids entirely.
- If pregnant or breastfeeding: COSRX's formula includes octinoxate, a UV filter some dermatologists advise avoiding during pregnancy due to potential hormonal activity; check with your clinician about which filters are appropriate for you specifically, in either product.
Bangladesh climate context
Bangladesh's high year-round sun exposure makes daily, reliable UVA/UVB protection non-negotiable regardless of which of these two you choose. Heat and humidity also make texture and reapplication comfort a real practical factor — a sunscreen that feels heavy or greasy is one people skip reapplying, which matters more here than in a cooler climate given how much sweating can shorten how long a morning application actually protects skin. Both formulas are marketed as lightweight and low on white cast, which suits Bangladesh's climate better than a heavier, occlusive sunscreen would.
How to apply either sunscreen correctly
Apply as the final step of your morning skincare routine, using a generous amount — most people under-apply sunscreen, which reduces the effective SPF regardless of which product you use. Reapply roughly every two hours if you're outdoors for an extended period, or sooner after heavy sweating, which is a real consideration during Bangladesh's hot months. If you experience pilling with either product, it's often a compatibility issue with a silicone-heavy serum or moisturizer underneath rather than a flaw in the sunscreen itself — simplifying the layers beneath it, or letting each layer absorb fully before the next, can help.
Mistakes and cautions
- Assuming a higher PA rating always means better protection for your situation. PA++++ vs PA+++ reflects UVA protection specifically; both offer high SPF50+ UVB protection, and correct, generous application matters as much as the rating itself.
- Ignoring fragrance allergens on the label because a product is marketed as "gentle" or "soothing." COSRX's aloe-forward marketing doesn't change that its formula contains added fragrance and recognized allergens.
- Not checking filter ingredients if pregnant. Octinoxate, present in COSRX's formula, is one some dermatologists advise limiting during pregnancy — check with a clinician rather than assuming either product is automatically fine.
- Layering under silicone-heavy products without adjusting. Both sunscreens can pill under certain moisturizers or primers; simplifying your under-layers helps more than switching sunscreens.

Beauty of Joseon carries a PA++++ rating compared to COSRX's PA+++, indicating a higher certified level of UVA protection on paper, though both provide broad-spectrum SPF50+ coverage.
Is either sunscreen reef-safe or mineral-only?
Neither is a mineral-only sunscreen. Beauty of Joseon uses fully organic (chemical) filters with no titanium dioxide; COSRX uses a hybrid of chemical filters and titanium dioxide. Check current reef-safety certifications on each brand's own page if this matters to your purchase.
