Ingredient analysis and how the ad lines read

Read on 2026-09-21

What is this product?

A Korean barrier cream from THE LAB by blanc doux, sold in 50 ml and 80 ml tubes as the last step of a single ingredient line built around low molecular weight hyaluronic acid. Its statutory list runs to 29 entries and prints levels for all three hyaluronic acid forms it carries: sodium hyaluronate at 3,010 ppm in position 11, hydrolyzed hyaluronic acid at 5 ppm and sodium acetylated hyaluronate at 0.5 ppm. Around them sit betaine, beta glucan and glycerin on the water side and a caprylic capric ester, meadowfoam and jojoba oils, mango seed butter, candelilla wax, a volatile hydrocarbon and two silicones on the lipid side, with two calming botanicals and a boswellia resin extract. Safety evidence is better documented here than the efficacy evidence: the brand reproduces two patch test report pages, 33 subjects in 2019 and 34 sensitive subjects in 2021, both showing zero response, while every performance figure traces to one 20 subject study measured before and after 72 hours. No fragrance entry, no essential oil and no drying alcohol appear in the printed list. No English ingredient list and no pH figure appear on any page read, and no lived use reports were collected.

What makes it different?

Prints a ppm level for every hyaluronic acid form it contains instead of leaving them undisclosed, and backs its comfort claim with two reproduced patch test report pages rather than with an asserted badge. The trade offs are that the trademarked soothing active the marketing leads with is never matched to any entry on the printed list, and that the comparison the brand builds its headline figure on names a product that does not appear in its own catalogue.

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.
