ISOI Moisture Dr. Cream

Ingredient analysis and how the ad lines read

Read on 2026-09-09

What is this product?

A 70 ml tube cream from ISOI built as a light hydrator rather than a rich barrier cream. It is also documented in unusual detail: the brand publishes eleven named tests with institution, date and sample size in the structured data on its own page. The reasons to skip it: the barrier and 100 hour hydration studies were run on a three-product regimen rather than on the cream alone; two percentage figures in the brand FAQ (123.38 and 121.58) have no matching row in that same test list; a named 독일더마테스트 appears with no grade; and 자몽껍질오일 with declared 리모넨 makes it a poor fit for essential-oil-reactive skin. No Korean functional cosmetic filing text appears on the surfaces examined here, and no pH figure was found.

What makes it different?

A light, humectant-led moisturiser whose brand page publishes eleven separately dated clinical and safety tests in structured data, where the useful reading is which of those tests were run on the cream alone and which on a three-product regimen.

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.

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

Did the ad claims hold up?

We checked 7 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.

  • It is a triple-care moisturizing cream that cares for barrier, moisture, and soothing at the same time. Plant-derived tea tree ceramide similar to skin and a powerful moisture pentahyaluronic acid complex help strengthen the skin barrier and improve hydration, while plant-derived ingredients such as purslane (Portulaca oleracea) and houttuynia cordata (fish mint) help soothe, restoring skin balance and filling dry skin with moisture to provide long-lasting softness.
