Mediheal Collagen Capsule Patch Vitamin C

Ingredient analysis and how the ad lines read

Read on 2026-09-11

What is this product?

Skip this one if you are buying it for the two things its name promises, because the statutory ingredient panel contains no collagen at all and the five vitamin C derivatives total about 0.1021 ppm, roughly one part in ten million. What the panel does carry is 나이아신아마이드 at a disclosed 20,000 ppm (2 percent), which is what actually earns the whitening half of its 미백 주름개선 functional filing, plus 아데노신 for the wrinkle half at an undisclosed level. It is a 60-sheet hydrogel under-eye patch with a gum-and-Irish-moss matrix that genuinely clings, sold with a built-in spatula and a 20-to-30-minute wear time.

What makes it different?

The separator is the gap between the name and the panel. Two headline ingredients in the product name, collagen and vitamin C, are respectively absent and present at trace, while the ingredient doing the regulated work is niacinamide at a disclosed 2 percent. That disclosure is itself unusual, since Korean labelling law does not require any concentration to be printed, and here it is what makes the mismatch visible instead of merely suspected. The second separator is exposure format: this is a 20-to-30-minute hydrogel contact on a contoured area, not a leave-on cream, so ingredient-list heuristics calibrated for leave-on products transfer poorly.

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.

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: 센티드제라늄꽃오일, 라벤더오일, 캐모마일꽃오일, 오렌지껍질오일, 멕시칸주니퍼오일, 카프릴릭/카프릭트라이글리세라이드, 스위트아몬드오일, 폴리글리세릴-10라우레이트, 폴리글리세릴-10아이소스테아레이트, 하이드로제네이티드레시틴, 스핑고모나스발효추출물

Did the ad claims hold up?

We checked 2 lines this product advertises against the ingredient list and public documents. None of them hold up on their own. They are partly right at best.

Claims translated from Korean, originals preserved.

Each line is quoted as the brand published it, and each one was read on its own against the ingredient list and the documents the brand publishes.
