Key actives

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. On this foam cleanser's own ingredient list it is named sixteenth.

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. It is named eleventh on this foam cleanser's list, alongside Allantoin.

Angelica Keiskei Extractplant extract

Ashitaba extract, a Japanese angelica relative rich in chalcones. It is used as an antioxidant conditioning extract. The panel names it twelfth on this foam cleanser's list, beside Allantoin.

Castanea Crenata (Chestnut) Shell Extractplant extract

Chestnut Shell Extract carries tannins and is used as an antioxidant plant extract, most often in formulas aimed at visible pores. It is named thirteenth on this foam cleanser's list, alongside Allantoin.

Salix Alba (Willow) Bark Extractplant extract

Willow Bark Extract carries salicin, the plant compound salicylic acid is related to. The two are not interchangeable: willow bark is a mild clarifying extract, not a BHA exfoliant at the levels used in cosmetics. The panel names it fourteenth on this foam cleanser's list, beside Allantoin.

How to use

  1. Work a small amount into a lather with water and massage over damp skin, then rinse thoroughly. Use in the morning, or as the second step of a nighttime double cleanse.

How it works

The ACNI Dr.1st Black Deep Cleansing Foam is a 75ml foam cleanser, used as your first step, morning and evening, on a face already wet with lukewarm water. The active it is built around is Allantoin, named sixteenth on its own ingredient list. The same list carries Houttuynia Cordata Extract, Angelica Keiskei Extract and Castanea Crenata (Chestnut) Shell Extract, so the active is not the only thing on it worth naming. How much of the Allantoin stays on the skin, and for how long, is decided by the foam cleanser format rather than by the list alone. This is the Original Korean Formula, the foam cleanser isoi sells in Korea, Allantoin and all.

Worth knowing

  • Introduce any new product gradually rather than adding several new steps to a routine at once, so a reaction is easy to trace back to the right cause.
  • Patch test on a small area first and wait a day before applying it to the full face, especially the first time you use it.

What professionals say

What professionals say

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.

    Wilma Bergfeld, MDDermatologist, Cleveland Clinic
  • Its potential for skincare is promoted because of its anti-inflammatory (think blemishes, rashes, eczema) and hydrating properties.
