What’s the deal with fluids?
First things first: what actually are these fluids? “They’re liquid cosmetic products, typically with a higher water content,” explains the biochemist and skincare specialist Vendula Ficelová of @biochemicka.vendy. “In Korean skincare they are usually referred to as toners or essences, or we sometimes call them face toners or hydrolates.” So it’s more about the consistency of the product rather than a clearly defined category, and you can look through a variety of sections when choosing them.
