Sulwhasoo First Care Serum VI
What a First-Step Essence Does

Updated July 2026 · Beauty Dupe editorial

Right after cleansing, skin has nothing on it yet, so whatever goes on first absorbs best. Yunjo Essence is built for that first moment: applied before toner, it softens skin and clears the way for everything that follows. We read all 50 lines of the label to see whether it is put together for that job.

The basics

There is a reason it sinks in so light

This essence spreads thin and dries fast for a reason: denatured alcohol is second on the label. Alcohol flashes cool across skin and evaporates, leaving that weightless feel. It is a fitting design for a first-step product, but if alcohol has irritated your skin before, this is the line to remember.

Behind it, humectants such as butylene glycol and betaine add the water and two silicones smooth the finish. That covers most of what is in the bottle. The herbal ingredients the name is built on come much further down.

Where the twelve herbal extracts really are

Herbal ingredients like rehmannia, peony, Solomon's seal, lotus and ginseng are used to comfort skin and lend moisture. This product carries 12 ingredients with the word extract in their name. On the label though, all but skullcap extract (13th) come after the fragrance (15th). Products typically use fragrance at around 1%, so everything after it likely stays under 1% each.

Extracts arrive diluted rather than as concentrates, so their numbers run small by nature. Still, it is worth knowing the distance between the expectation the name builds and the amount actually inside.

The ingredients doing the clearest work for skin are the unfamiliar names. Adenosine, a notified anti-wrinkle active, sits relatively high at 16th. Madecassoside, drawn from centella to calm stressed skin, sits 26th, and a tone-evening vitamin C derivative sits 30th. Their doses run small back there, but on this label the functional weight rests on these three rather than on the herbs.

What this essence does well, and what not to ask of it

Group the ingredients by what they do and hydration covers the most ground. Humectants add water while the alcohol flashes off light, faithful to the first-step boosting job.

Soothing, tone and firmness are shared by madecassoside, the vitamin C derivative, adenosine and ginseng extract. All of them come after the fragrance, so the doses are small. The directions are there, but they are not the reason to buy this bottle.

What not to ask of it is just as clear. It will not finish your hydration alone: with almost no oil, dry skin needs a cream afterward. There is no exfoliating acid or retinoid either, so leave that work to other steps.

What to note

There are no parabens and no mineral oil. It does contain fragrance, and limonene, linalool, citronellol, citral and geraniol are listed separately under the rule that requires fragrance allergens to be spelled out. Together with the denatured alcohol in second place, scent- or alcohol-reactive skin should start with a small amount.

Whose skin it suits

It fits oily and combination skin that wants a fresh first step. In a multi-layer routine, the light texture that never gets in the next product's way becomes its real advantage.

Dry skin can use it as a starting point only and fill in moisture at later steps. If alcohol or fragrance sets off your skin, let the note above make the call.

How to read this blend

So this is a light first-step essence built on alcohol and humectants, with twelve herbal extracts riding along in small doses. The functional weight rests on adenosine and madecassoside. If you are curious how your own essence is built, the button below runs the breakdown.
