What is hyaluronic acid and how do you use it?
Hyaluronic acid is a humectant that draws water into the skin for a plumper, hydrated look. In Korean routines it's best applied to damp skin and sealed with a moisturizer on top, so the moisture it attracts stays locked in rather than evaporating.
What is essence in Korean skincare?
Essence is a lightweight, watery Korean skincare layer applied after toner and before serum. It's designed to hydrate and prep the skin so later products absorb better. Often fermented or ingredient-rich, essence is sometimes called the heart of a Korean routine.
What is the difference between essence and serum?
In Korean skincare, essence is typically a thinner, hydration-focused layer that preps skin, while serum is more concentrated with targeted actives like vitamin C or niacinamide. Essence usually comes first; serum follows. The line between them blurs, and not every routine needs both.
What is a Korean toner and how is it different?
In Korea, toner (called 'skin' or 'skin toner') is usually a gentle, hydrating step that preps and balances skin after cleansing, rather than a harsh astringent. It's meant to add moisture and help following layers absorb, not to strip or tighten the skin.
