| What it is | 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. | The vitamin C derivative Korean brands use when they want a serum that does not turn orange by March. Korea's MFDS lists it among the notified 미백 (mibaek, brightening) functional actives, which means a product carrying that mark on its strength contains a regulated amount. Gentler than L-ascorbic acid, and slower. |
| Best for | Dullness & glow | Dark spots & tone, Dullness & glow, Sun damage & photoageing |
| When to use | BOTH | AM |
Which should you choose?
Choose Pearl Extract if your priority is Dullness & glow; choose 3-O-Ethyl Ascorbic Acid for Dark spots & tone. Many Korean routines use both — yes — they layer well together.
