What is this product?

Skip this if denatured alcohol or fragrance allergens are a problem, because both are in it and the marketing does not say so. The olive young ingredient record for goods_no A000000204633 lists 50 items opening 정제수, 변성알코올, with 향료 fifteenth and five notified allergens (리모넨, 리날룰, 시트로넬올, 시트랄, 제라니올) declared. Reasons to use it: a light first essence step for oily or combination skin, carrying 아데노신, 3-O-에틸아스코빅애씨드, 마데카소사이드 and a ginseng and herbal extract block, with no exfoliating acid anywhere in the list. The brand's cited support is a two week customer satisfaction footnote with no institution, sample size or date. The record states the functional cosmetic filing was completed but not for which function, and no pH or concentration was found in the surfaces checked.

What makes it different?

A luxury tier herbal first essence whose second ingredient is denatured alcohol and whose only cited evidence is an uncredentialed two week satisfaction survey run partly in combination with another product.

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.

Key ingredientWorth a closer look

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: 하이드로제네이티드레시틴
