Which One Should You Buy?
Choose Beauty of Joseon Relief Sun if you prioritize established reliability and versatility. With nearly 9,000 reviews and a 4.9-star rating, it offers proven SPF50+ PA++++ protection in a lightweight cream suitable for daily face and body use year-round. The dual 50mL pack delivers strong value at $25.47. This works well for those seeking a dependable, non-sticky formula without concerns about sensitive skin or oily skin performance.
Choose Round Lab Birch Juice if you have dry skin and prefer mineral sunscreen. The combination of birch sap and hyaluronic acid addresses dryness, while non-nano zinc oxide appeals to those wanting a gentler mineral filter for sensitive skin. The bundle format (50mL + 20mL) offers reasonable longevity despite the $28.42 price point. Be aware this is better suited to dry skin; oily skin users may find it less ideal, and the smaller review base (32 reviews) provides less established consumer feedback than its counterpart.
Bottom Line
The value pick is Beauty of Joseon Relief Sun: Rice + Probiotics at $25.47. Either way, both are proven bestsellers with strong ratings from Korean shoppers — pick the one whose finish and formula fit your skin.
