Ingredient analysis and how the ad lines read

Read on 2026-09-30

What is this product?

CKD Guaranteed Retino Collagen Low-Molecular 300 Pore Elasticity Mask is a single-use hydrogel sheet mask (31 g per sheet, sold in a 6 sheet pack on the brand's own store) carrying a whitening and wrinkle-improvement functional notation. Its 36 entry list, printed on a notice image, pairs collagen at 1,748 ppm and retinal at 500 ppb with niacinamide, adenosine, sodium hyaluronate, hydrolyzed elastin, several gelling gums and a bergamot oil entry. The brand says to leave it on for about 30 minutes until the sheet turns clear. No fragrance entry and no exfoliating acid entry is printed.

What makes it different?

A hydrogel sheet that discloses both collagen (1,748 ppm) and retinal (500 ppb) levels on its list and carries a two-function notation; its three cited two-week test charts have no control group and two of them do not reproduce from their own bars.

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.
