MEDICUBE PDRN Pink Caffeine Collagen Eye Patch

Ingredient analysis and how the ad lines read

Read on 2026-09-19

What is this product?

A pink hydrogel under eye patch from MEDICUBE, 60 patches at 85 g, worn for a printed 10 minute session with an included spatula and then removed. The sheet is set on Irish moss powder with carob, guar and cellulose gums. Under it sits a very heavy water binding payload: 10 hyaluronic acid forms, 7 collagen forms including atelocollagen and desamido collagen, 8 free amino acids and 9 acetyl or palmitoyl peptides. Nine concentrations are published, from caffeine at 100 ppm down to sodium DNA and procollagen at 10 ppb, and the marketing leans on the caffeine one for a puffiness and dark circle story that 0.01 percent does not carry. The product is filed in Korea as a dual function cosmetic for whitening and wrinkle improvement, with niacinamide third and adenosine nineteenth on the list. Retinol is present at position 39 with no percentage published. No fragrance entry, no exfoliating acid and no drying alcohol appear in the 73 printed ingredients.

What makes it different?

Nine published concentrations on one label against 2 on the line mate whose own list was harvested for this record, and they run from 100 ppm down to 10 ppb so the disclosure works against the marketing rather than for it. The product carries a Korean dual function registration for whitening and wrinkle improvement with both notified actives high on the list, while the copy sells puffiness and dark circles on 0.01 percent of caffeine. Retinol in an under eye patch with no percentage published is the other thing that separates it.

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 1 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.

We could not place these in the list above: 폴리글리세릴-10라우레이트, 카프릴릭/카프릭트라이글리세라이드, 돌콩오일, 레티놀
