DENOISE DENOISE LONGEVITY BARRIER SERUM

Ingredient analysis and how the ad lines read

Read on 2026-09-29

What is this product?

DENOISE LONGEVITY BARRIER SERUM is a 30 ml barrier positioned serum in an airless pump, marked as a whitening and wrinkle improvement dual functional cosmetic. Its 33 entry list starts with water, glycerin, methylpropanediol, a silicone and an ester, carries niacinamide and adenosine early, and puts six ceramides, cholesterol, fatty acids, sterols and an NAD entry in the second half, with panthenol and glyceryl glucoside named by the brand. No fragrance, essential oil or ethanol entry is listed, and a PHA-class entry sits at 19. The brand cites a one week after stopping retention test on 22 women, an irritation test on 31 adults and a perception survey, none with printed underlying values. The list comes from the printed label image on the brand's own store, read once, with no second surface.

What makes it different?

A ceramide and NAD barrier story on a dual functional base, with the six ceramide count matching the list. The trade off is that the headline 168 hour barrier claim rests on moisture, wrinkle and lifting retention figures with no printed values and no barrier measure.

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.

Worth 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.
