Ingredient analysis and how the ad lines read

What is this product?

A gel-type sheet mask built around niacinamide, hydrolyzed DNA (100 ppm), peptides, proteoglycan and multiple collagen and hyaluronic derivatives, aimed at hydration and elasticity care. It is fragrance-free and free of drying alcohols and essential oils, making it friendly to sensitive skin.

What makes it different?

The formula pairs the brand's signature hydrolyzed DNA at a disclosed 100 ppm with a broad supporting cast: niacinamide at the fifth position, adenosine, a peptide, soluble proteoglycan, fibronectin, collagen, elastin and five forms of hyaluronic acid-related materials. It is a genuine gel-base mask with carob gum, Irish moss and algin rather than a thin essence sheet. Only hydrolyzed DNA carries a printed concentration; every other hero ingredient is undisclosed, so the actual strength of the blend cannot be judged from the list alone.

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 2 with no dictionary entry, left in Korean.

Key ingredient

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