| What it is | The quiet workhorse of almost every Korean toner and cream. Glycerin is one of the most studied humectants in cosmetics — unglamorous on an ingredient list, but it is doing much of the hydrating you credit to fancier actives. | Like birch sap, bamboo water is used as a lighter-feeling base. It shows up most in gel textures aimed at Korea's humid summers, where anything richer feels unbearable. |
| Best for | Dryness & dehydration, Dehydration (water-poor skin), Damaged moisture barrier | Dehydration (water-poor skin), Oil control, Reactive & easily-stung skin |
| When to use | BOTH | BOTH |
