cecith Waterlock First Serum

What is this product?

A 150ml two-phase first serum dispensed as foam from a pump, with ten hyaluronate forms verified by position and 호호바씨오일 at position 4 of 36. Not a filed functional cosmetic: the statutory table reads 기능성여부 해당사항없음 and the panel carries no filed brightening or anti-wrinkle ingredient. It publishes per-ingredient concentrations for its two surfactants, 코코-베타인 at 0.03 percent and C12-14알케스-12 at 0.2 percent against a stated 0.3 percent ceiling, used for emulsification rather than cleansing, while every other ingredient level is undisclosed, and its irritation study names a laboratory, a date window and a 32-person panel aged 28 to 63 with a verdict of 저자극 범위. Against that, the efficacy evidence is a single in-house thirty-second before-and-after image with no panel size or instrument, several sales and ranking claims carry no evidence at all, aquaporin is printed on the bottle as though it were an ingredient when it is a skin protein absent from the panel, and the irritation index is printed with a percent sign.

What makes it different?

Two separators, and the first is rare enough to lead with. This label publishes actual percentages for its two surfactants together with the purpose they serve, and the printed ingredient order agrees with those numbers. Every other ingredient on the panel is undisclosed, so the two figures are the whole of what this product tells you about levels. The second is the internal split in evidence quality. The safety study here names its laboratory, a three-week window and 32 subjects with ages and sexes stated, while the efficacy behind the headline claim is one in-house image read at thirty seconds with none of those things. A reader who wants to know what is actually in the bottle, and whether it was tested for irritation, will find both answered here; a reader who wants evidence that it works will find a gap the same page proves the brand could have closed.
