KAREMEDI JOURNAL · INGREDIENTS · UPDATED 2026-10-01

Heartleaf, or eoseongcho in Korean, is a calming botanical used for oily and blemish-prone skin. Here is how it works and how to use it.

What heartleaf is

Houttuynia cordata is a heart-shaped leafy plant common in East Asia. Korean skincare uses its extract, called eoseongcho, in toners, pads and spot products.

Why it's popular

Heartleaf is used to calm the look of redness and keep oily skin feeling balanced. It is gentle enough for daily toners.

Building a blemish routine

Use a heartleaf toner after cleansing, a light moisturizer, and a hydrocolloid patch on individual spots overnight. See our pimple patch guide.

Frequently asked questions

Does heartleaf smell?

The raw plant has a fishy smell; finished products are usually mild.

Can I use heartleaf with salicylic acid?

Yes, but introduce one new product at a time.
