Heartleaf (houttuynia) skincare: why it went viral and where it costs least

Heartleaf, houttuynia cordata or 어성초: the soothing plant behind some of K-beauty's best-known toners. What it is, and where each heartleaf product is cheapest today.

Heartleaf (houttuynia cordata, 어성초 in Korean) is a plant brands use in calming and oil-balancing products. It became famous abroad through heartleaf toners that sold out again and again, and now nearly every big brand has a heartleaf line.

Our view: the hype is mostly about texture. Heartleaf toners are usually watery and light, which suits oily and combination skin that wants something calming without heaviness. Because they are stocked everywhere, prices vary a lot, so check the table before you buy.

Picks are the products the most stores in your country stock, shown cheapest first, so the table changes as stores restock and reprice. Nothing here is medical advice: patch test new products, and see a dermatologist for skin problems that don't settle. More from the blog.
