Key actives
Sodium DNAactive
Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to. On this cleansing oil's own ingredient list it is named twenty-second.
Tocopherolantioxidant
Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer. The panel names it thirtieth on this cleansing oil's list, beside Sodium DNA.
Rosa Damascena Flower Extractplant extract
Damask rose flower extract, the rose grown for perfume. It carries tannins and flavonoids and is used as a conditioning extract. It is named twenty-third on this cleansing oil's list, alongside Sodium DNA.
Olea Europaea (Olive) Fruit Oilemollient
Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it. The panel names it second on this cleansing oil's list, beside Sodium DNA.
Macadamia Ternifolia Seed Oilemollient
Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin. The panel names it sixth on this cleansing oil's list, beside Sodium DNA.
How to use
- Massage into dry skin and face to dissolve makeup and sunscreen, then emulsify with a little water and rinse, or follow with a water-based cleanser.
Where does this cleansing oil go in my routine?
As the first of two evening cleanses, on dry skin and dry hands, before any water reaches the face. Nothing goes under it: this cleansing oil is the step everything else in the routine lands on top of. 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 Sodium DNA and not three changes at once.
Is this the Korean-market cleansing oil or a US version?
The Korean-market one, Sodium DNA and all. We match this cleansing oil to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
Does this cleansing oil contain fragrance?
Yes. The ingredient list names Citronellol and Linalool. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this cleansing oil is not the one.
What else is on the list besides Sodium DNA?
Tocopherol, Rosa Damascena Flower Extract and Olea Europaea (Olive) Fruit Oil. The order they are printed in on this cleansing oil's panel is the order on the box, so you can see where Sodium DNA sits relative to them. Further down the same panel: Macadamia Ternifolia Seed Oil, Vitis Vinifera (Grape) Seed Oil and Prunus Armeniaca (Apricot) Kernel Oil.

How it works
The Brightening Cleansing Oil is a 150ml cleansing oil, used as the first of two evening cleanses, on dry skin and dry hands, before any water reaches the face. The active it is built around is Sodium DNA, named twenty-second on its own ingredient list. The same list carries Tocopherol, Rosa Damascena Flower Extract and Olea Europaea (Olive) Fruit Oil, so the active is not the only thing on it worth naming. How much of the Sodium DNA stays on the skin, and for how long, is decided by the cleansing oil format rather than by the list alone. This is the Original Korean Formula, the cleansing oil isoi sells in Korea, Sodium DNA and all.
Worth knowing
- Patch test this cleansing oil on a small area and wait a day before using it more widely, especially with Sodium DNA on the list.
- This list names Citronellol and Linalool, so skip it if fragrance components are something you avoid.
