How Tranexamic Acid works νΈλΌλ₯μΌμ°
Tranexamic acid is a lysine derivative that helps interrupt the signaling between skin and pigment-producing cells (in part via the plasmin pathway), making it a favorite for the look of stubborn pigmentation and melasma, frequently paired with niacinamide. Cosmetic topical concentrations are modest and not rigidly standardized.

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.
How long does Korean skincare take to work?
Most skincare, Korean or otherwise, needs time. Hydration benefits can appear quickly, but visible changes in tone, texture or fine lines typically take several weeks to a few months of consistent use, roughly one skin cycle or more. Sun protection and patience matter more than any single product.
