What a first-step essence does

This is a boosting essence you apply right after cleansing, before toner. Its job is to soften bare skin and help whatever comes next sink in.

The fresh, fast-drying feel has a reason. After water, the largest ingredient is denatured alcohol, which spreads cool and then evaporates, leaving a light finish. Humectants such as butylene glycol and betaine add the hydration.

The herbal extracts in the name number twelve, including rehmannia, peony, Solomon's seal, lotus and ginseng. They are used to comfort skin and support hydration, but extracts come in diluted, and the list also includes fragrance, which can be listed in any order, so how much of each is inside is hard to tell.

The less familiar names do clearer work: adenosine, on Korea's anti-wrinkle functional list; madecassoside from centella, known for calming irritated skin; and a vitamin C derivative that evens out tone. All three are used in small amounts, so what matters is that they are there.

Who it suits

It suits oily and combination skin that wants a fresh first step. If you layer many products, its light texture stays out of the way of what follows.

Dry skin should use it only as a starting point and add a cream afterward. It has almost no oil, so it cannot do the moisturizing alone.

What to watch

It contains alcohol and fragrance. Limonene, linalool, citronellol, citral and geraniol, allergens in the fragrance, are also listed by name because the rules require it. If alcohol or scent has bothered your skin before, test it on a small area first.

It has no parabens or mineral oil. There is no exfoliating acid or retinoid either, so leave those to another step.

Cheaper alternatives

We matched its full ingredient list against dupes that share its key ingredients. They overlap on the vitamin C derivative or calming side, so they suit people who want a similar role at the serum step rather than as a first step.
