View at retailer →Dokdo, heartleaf and barrier toners — the Korean toners charting this week, from splash to soak.

The Korean toner isn't an astringent; it's a hydrating layer you can drench or pat in. We pulled the toners charting in Olive Young's skincare bestsellers this week and curated for the jobs people actually buy them for — barrier calm, soothing, and simple daily hydration.

2A 77% heartleaf toner built to calm redness and prep stressed skin. Watery, fragrance-light, and easy to layer — the soothing step in a lot of routines.
3A derma-leaning ceramide toner aimed at dry, compromised barriers. Less refreshing splash, more first layer of repair — the pick for tight, flaky skin.
4A large-format tea-tree and cica toner for breakout-prone skin that wants soothing without stripping. The one people go through by the bottle.
5A low-molecular hyaluronic toner that sinks in fast and layers clean under everything. The featherweight option for combination skin.
