| Kojic Acid | Pearl Extract | |
|---|---|---|
| What it is | A by-product of the same koji fermentation used to make sake and soy sauce. It can be sensitising for some people, so it is usually formulated at modest levels and in company with gentler brighteners. | Ground pearl appears in Korean royal-court beauty lore and still anchors premium hanbang lines. Be clear-eyed about it: much of the immediate 'glow' is optical, from finely milled particles catching light. |
| Best for | Dark spots & tone, Melasma & stubborn patches, Dullness & glow | Dullness & glow |
| When to use | PM | BOTH |
Which should you choose?
