Our Pick
COSRX
Higher editor rating (9 vs 8.5)
One-day's You
One-day's You is the K-beauty brand that nailed the "I want one good cleanser, one good sunscreen, one good moisturizer" energy. The Helio Vital Sunscreen has a quiet cult following — dewy finish, no white cast, layers like a dream — and the Real Birch Cleansing Oil is a sleeper among Korean cleansing-oil heads. Approachable pricing, clean labels, and packaging that actually looks good on a shelf.
Pros
- ✓ Excellent dewy-finish sunscreen
- ✓ Approachable price point
- ✓ Clean fragrance-free formulations
- ✓ Cute, magazine-worthy packaging
Cons
- ✗ Smaller hero-product range
- ✗ Less coverage from English-language reviewers
- ✗ Sometimes hard to source outside Asia
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
