PhilosophyRohto UV science for the lightest possible sun protectionMinimal, effective formulations at accessible prices. Every product built around one or two proven actives with short, transparent ingredient lists.
Skin Aqua
The sunscreen brand that proved SPF50+ can feel like wearing nothing — Japan most popular budget UV line.
Pros
- ✓ Lightest textures in sunscreen
- ✓ SPF50+ PA++++
- ✓ Under $12
- ✓ No white cast
Cons
- ✗ Contains alcohol in some formulas
- ✗ Small bottles
COSRX
The gateway brand for most people entering K-beauty, and for good reason. COSRX consistently delivers effective, no-frills products at prices that make most Western alternatives look overpriced. Their snail mucin line and BHA products are genuine category leaders. They rarely innovate, but they execute the basics exceptionally well.
Pros
- ✓ Outstanding value across the entire range
- ✓ Short, transparent ingredient lists
- ✓ Consistently effective formulations
- ✓ Widely available globally
Cons
- ✗ Packaging is utilitarian, not luxurious
- ✗ Rarely pushes boundaries with new ingredients
- ✗ Some products have a faint tea tree scent
