Our Pick
O HUI
Larger product range
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
- โ Long track record on PIH and dark spots
- โ Damask rose hero ingredient
- โ Hwahae 2025 award winner
Cons
- โ Premium pricing
- โ Heavier rose scent
O HUI
O HUI is the LG H&H luxury skincare brand most international K-beauty fans haven't discovered yet. Founded in 1997 as a clinically-positioned alternative to the brand's hanbang luminaries (The History of Whoo, Sulwhasoo), O HUI built its identity on the The First Geniture line โ stem-cell-based anti-aging cosmeceuticals at premium pricing. The brand sits roughly between the prestige and ultra-prestige tiers of K-beauty, with The First Geniture Ampoule and Cream as the flagship products and the Prime Advancer line as the daily-routine tier. Korean dermatologists and aestheticians stock O HUI alongside Sulwhasoo and Whoo as the LG H&H luxury triumvirate.
Pros
- โ LG H&H luxury K-beauty pedigree alongside Whoo and Sulwhasoo
- โ stem-cell-based The First Geniture anti-aging line is genuinely differentiated
- โ clinical-luxury positioning bridges the hanbang and modern cosmeceutical tiers
- โ international distribution growing through Korean department store partnerships
