    What is heartleaf in skincare?

    Heartleaf is the K-beauty name for Houttuynia cordata, a calming herb rich in antioxidant flavonoids. It soothes the look of redness and supports stressed, blemish-prone skin, which is why it anchors so many Korean calming toners and essences.

    What does heartleaf do for skin?

    Heartleaf calms redness-prone skin and adds antioxidant protection.

    Research on Houttuynia cordata found its flavonoids attenuate UVB-induced damage in human skin cells.

    It pairs naturally with Centella Asiatica in calming routines and suits skin that flushes, stings, or breaks out under stress. Expect comfort and a calmer look rather than dramatic change.

    Who should use heartleaf?

    Heartleaf suits redness-prone, acne-prone, sensitive, or stressed skin, and anyone building a gentle K-beauty calming routine. It is well tolerated and layers under actives.
