Our Pick
Mediheal
Higher editor rating (9 vs 8.6)
Isoi
Isoi has been quietly excellent for nearly two decades, but 2025 is its breakout year. The Blemish Care Up Serum picked up multiple Hwahae nods, and dermatology-leaning K-beauty fans have been quietly recommending it for fading post-acne marks for years. Premium-leaning but worth it.
Pros
- ✓ Long track record on PIH and dark spots
- ✓ Damask rose hero ingredient
- ✓ Hwahae 2025 award winner
Cons
- ✗ Premium pricing
- ✗ Heavier rose scent
Mediheal
Mediheal is the top-selling skincare brand at Olive Young for two years running — beating more than 3,000 brands. Their sheet masks created the modern sheet mask category, and their Madecassoside Blemish Pad saw 820% year-over-year growth. If you only add one new sheet mask brand to your routine, make it this one.
Pros
- ✓ #1 selling brand at Olive Young
- ✓ Clinical-grade sheet mask formulations
- ✓ The Madecassoside line is category-defining
- ✓ Affordable daily-use pricing
Cons
- ✗ Sheet masks are single-use and generate waste
- ✗ Some older lines contain fragrance
- ✗ Huge catalog can be overwhelming
