Our Pick
Rejuran
Higher editor rating (8.7 vs 7)
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
Rejuran
Rejuran is the consumer-skincare arm of Pharma Research Products, the Korean biopharma company that developed the original Rejuran Healer injectable — the same PDRN (polydeoxyribonucleotide) dermal treatment that's been a staple of Korean aesthetic clinics since 2014. The topical line translates that clinical DNA into daily-use products, anchored by the patented c-PDRN® complex at 0.5% concentration plus proprietary DOT® (Dermal Optimizing Technology) delivery. The Turnover Ampoule is the hero: a lightweight serum that targets fine lines, firmness, and texture with the same salmon-DNA active that made the injectable famous. Rejuran launched at Sephora US in 2024, won the 2025 Olive Young Slow Aging award, and has become the face of the PDRN trend that's dominating K-beauty in 2025–2026. The price point is premium-mid ($45–55), justified by the clinical pedigree and patented delivery system. Worth reaching for if you want the PDRN trend from the company that actually invented it.
