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
