Ingredient analysis and how the ad lines read

Read on 2026-09-22

What is this product?

A water-based gel-type sleeping mask built on humectants, centella actives, ceramide NP and two peptides, with niacinamide and adenosine backing its brightening and wrinkle-improvement functional notice. Reasonable for overnight hydration and barrier support, though no concentration or test data is printed.

What makes it different?

The formula pairs a centella complex (asiaticoside, madecassic acid, asiatic acid) with ceramide NP, salmon egg extract and two peptides in a single overnight step. Niacinamide sits near the top of the list at position six, higher than most marketing-led sleeping masks place it. The full amino acid set is included, which is unusual but likely at low levels given the late positions. The dual functional registration covers brightening and wrinkle improvement, while firming claims rest on ingredients rather than disclosed testing.

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.
