PhilosophyAcid-forward, results-driven formulations targeting acne and troubled skin. The '30 Days Miracle' line is their core concept.Damask rose, deeply.

Some By Mi

Some By Mi's marketing is aggressive — '30 Days Miracle' is a bold claim for any skincare product. Strip away the hyperbole and you'll find competent acid-based formulations at reasonable prices. The AHA BHA PHA Toner is a decent daily exfoliant for oily skin. Just don't expect miracles in 30 days or any other timeframe.

Pros

✓ AHA/BHA/PHA combination is well-executed
✓ Budget-friendly acid products
✓ Good entry point for chemical exfoliation
✓ Wide availability

Cons

✗ Marketing claims are wildly overblown
✗ 'Miracle' branding sets unrealistic expectations
✗ Tea tree scent is strong
✗ Can be too drying for non-oily skin types

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.
