Name: O'earth Triple Layered Hyaluroncica 7sec Serum In Ampoule
Brand: O'earth

What is this product?

O'earth's Hyaluroncica 7sec Serum In Ampoule is a 105ml water-gel hydrating serum, roughly twice the usual serum volume. Its 41 ingredients carry no lipid at all in the first eleven entries, and within that list the oil-adjacent materials are 스쿠알란 at 36 plus three entries at 39 through 41, so it hydrates without adding oil. Eight hyaluronate-class entries span a range of molecular weights, with disclosed figures of 소듐하이알루로네이트 500ppm at position 14 down to 소듐아세틸레이티드하이알루로네이트 0.7ppm. The soothing half is well populated: 알란토인 at 11, 병풀잎추출물 at 13 at 800ppm, 병풀추출물 at 17 at 300ppm, plus four centella derivatives. Structure comes from carbomer at 9 alone, with no film former, silicone or wax, so it leaves no film and absorbs fast. What overstates: the brand's 11중 히알루론산 counts eleven hyaluronic forms against eight on the statutory panel, and both 7초 and 검증앰플 rest on no test information found on any surface held, while an English version of the claim on a third-party listing asserts a completed clinical study with nothing behind it. There is one ceramide at position 40 and no barrier lipid system, so this is the hydration step and not the sealing step. The panel comes from a retail surface, not a brand-published one.

What makes it different?

Three things separate it from neighbouring hydrating serums. First, the hydration is genuinely lipid-free at the top of the order: eleven entries with no oil phase at all, which makes it a rarer fit for dehydrated oily skin than the category's usual water-and-oil emulsions. Second, its concentrations are actually published through its statutory record, a ppm ladder from 800 down to 0.7, which is unusual enough that a reader can see exactly how the hyaluronic stack is weighted rather than inferring it from order alone. Third, and least flattering, it is a clean worked example of a product name carrying a count the statutory panel does not support, eleven against eight, alongside a second-hand English claim of a completed clinical study that no surface held substantiates.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary, except 3 with no dictionary entry, left in Korean.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

We could not place these in the list above: 폴리글리세릴-10라우레이트, 카프릴릭/카프릭트라이글리세라이드, 스쿠알란
