Ingredient analysis and how the ad lines read

Read on 2026-10-02

What is this product?

A hydrogel collagen mask from the Korean brand COCI, sold on the brand storefront with a statutory notice image that prints 34 ingredient entries. Soluble collagen leads the list with a printed amount bracket, ahead of water, followed by glycerin, an acrylates copolymer and niacinamide, with adenosine at 20 and ceramide NP at 27. The notice carries a whitening and a wrinkle improvement effect line. No fragrance, alcohol or essential oil entry is printed, and no exfoliating acid entry is printed (one citric acid entry sits at 25). The brand shows a 30 adult patch test with no reaction and pore and moisture charts whose drawn bars do not match their printed labels.

What makes it different?

Soluble collagen printed first with an 800,250 PPM bracket, plus a notice that carries both whitening and wrinkle improvement wording and no fragrance entry. The brand's pore and moisture charts do not reconcile with their own bars, and one English intro line names squalane that the printed list does not contain.

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.

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