Ingredient analysis and how the ad lines read

Read on 2026-09-21

What is this product?

A firming and radiance oriented sheet mask whose essence is built on niacinamide, adenosine, hydrolyzed DNA, nicotinamide mononucleotide and a five peptide complex, with three forms of hyaluronic acid for hydration. It suits those wanting a brightening and anti-aging ampoule style mask without added fragrance.

What makes it different?

The formula pairs niacinamide at sixth position with adenosine at eighteenth, then places hydrolyzed DNA and nicotinamide mononucleotide in the later half alongside five peptides including acetyl hexapeptide-8 and copper tripeptide-1. Hyaluronic acid appears in three forms, namely hyaluronic acid, hydrolyzed hyaluronic acid and sodium hyaluronate, near the end of the list. The essence contains no fragrance, no essential oils and no drying alcohols, keeping it gentle on paper. All active concentrations are undisclosed, so expected strength cannot be judged from the ingredient list alone.

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