It is thin enough to pass for water, spreading out the moment it lands and leaving no tack and no film, so cotton pads or the products that follow sit on top without any argument.

【An ingredient list you can read at a glance】
Three ingredients, and nothing else. The formula is built around eight omissions, on the principle that the less surplus there is, the more directly what matters reaches the stratum corneum.

【Coix seed: a Japanese-Chinese herbal extract】
Coix has long been used in both beauty and cooking, and is a familiar health-tea ingredient in Japan. This solution draws on the seed specifically — the amino acids and other compounds a seed needs in order to germinate are concentrated there, and the extract is taken from that.

【Steadies skin that keeps shifting】
Coix seed extract works in this formula as a moisturising ingredient, settling a complexion that reacts easily to its surroundings and bringing it back to something more even.

【Guards against dryness turning into roughness】
It adds moisture back into drier skin so that dryness stops circling back as rough patches. On days of seasonal change or short sleep it can be used continuously.

Suitable for: skin that swings with the seasons, roughness that keeps returning, and dryness on top of both. Also a good place to begin if you prefer the shortest possible ingredient list.

How to use: After cleansing, apply your toner first, then take about 2 to 3 drops of the solution into your palm and press evenly over the face; go over rougher areas a second time. Finish with an emulsion or cream to seal the moisture in. If you are adding undiluted solutions to a routine you already have, this is the one whose job is to settle things down first.

Patch-test on the inner arm before first use. If redness, itching or stinging occurs, stop use and consult a dermatologist.
