Both are excellent. Here's which one to pick based on your needs.
The rice probiotics formula adds skincare benefits while protecting. Creamier texture doubles as a light moisturizer for dry skin types.
The birch juice base is incredibly lightweight and absorbs almost instantly. Perfect for oily skin that hates any heaviness.
Everything you need to know before choosing.
Round Lab Birch Juice has a lighter, more watery texture that absorbs faster, making it slightly better for oily skin. Beauty of Joseon has a creamier feel that works well for normal to dry skin.
Neither leaves a noticeable white cast on light to medium skin tones. Both use chemical UV filters that blend invisibly. On deeper skin tones, Beauty of Joseon may show a very slight cast due to its creamier base.
Beauty of Joseon Relief Sun is typically $12-13 for 50ml on Yami. Round Lab Birch Juice is around $15-18 for 50ml. Beauty of Joseon offers better value per ml.
You don't need to. Both provide SPF50+ PA++++ protection on their own. Layering won't increase protection and may cause pilling. Pick the one that matches your skin type and stick with it.
Both work well under makeup if you wait 2 minutes after application. Round Lab's lighter texture pills less with silicone-based foundations. Beauty of Joseon pairs better with water-based foundations.
Both are top-tier Korean sunscreens. You can't go wrong with either.
