Key actives
Houttuynia Cordata Extractplant extract
Houttuynia Cordata is heartleaf, and it is one of the two or three anchor plants of Korean calming skincare. Its extract carries quercitrin and other flavonoids and is used for the look of redness and blemish-prone skin. The name on the box points at it, and it is named second on this serum's own ingredient list.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it fifteenth on this serum's list, beside Houttuynia Cordata Extract.
Madecassosideactive
Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams. The panel names it eighteenth on this serum's list, beside Houttuynia Cordata Extract.
Asiaticosideactive
Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised. The panel names it nineteenth on this serum's list, beside Houttuynia Cordata Extract.
Madecassic Acidactive
Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula. It is named twenty-third on this serum's list, alongside Houttuynia Cordata Extract.
How to use
- Use this serum AM and/or PM, as the serum step, after toner or essence and before moisturizer. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Houttuynia Cordata Extract and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Houttuynia Cordata Extract and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Houttuynia Cordata Extract?
Allantoin, Madecassoside and Asiaticoside. The order they are printed in on this serum's panel is the order on the box, so you can see where Houttuynia Cordata Extract sits relative to them. Further down the same panel: Madecassic Acid, Asiatic Acid and Tocopherol.

How it works
The HEARTLEAF 100 Serum is a 40ml serum, used after toner and before moisturizer, morning and evening. The plant extract it is built around is Houttuynia Cordata Extract, named second on its own ingredient list. The same list carries Allantoin, Madecassoside and Asiaticoside, so the plant extract is not the only thing on it worth naming. How much of the Houttuynia Cordata Extract stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum DEWYTREE sells in Korea, Houttuynia Cordata Extract and all.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Houttuynia Cordata Extract on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Houttuynia Cordata Extract rather than to three changes at once.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

Its potential for skincare is promoted because of its anti-inflammatory (think blemishes, rashes, eczema) and hydrating properties.
