Ingredient analysis and how the ad lines read

Read on 2026-09-09

What is this product?

Take this shade if organic filters bother you and you still want coverage: 01 Blur is mineral-only, zinc oxide second and titanium dioxide thirteenth, with mica and three iron oxides building a beige, and no fragrance ingredient and no denatured alcohol in its 54 item list. Centella leaf water leads the whole list, ahead of purified water at position 30, and a small ceramide and cholesterol set sits behind it. The thing to know before ordering: this is one product page selling two shades, and 02 Glow is a different formula, 68 ingredients, hybrid filters, with a fragrance ingredient and denatured alcohol, from a different manufacturer. The tolerance properties change with the dropdown. Also, every testing claim made for this product sits on a US retailer page, not a brand one, with no institution or subject count named.

What makes it different?

A shade option whose formula differs from its page-mate on almost every tolerance axis at once, mineral against hybrid, fragrance-free against fragranced, alcohol-free against denatured-alcohol-bearing, and made by a different contract manufacturer, while both are sold under one shared product name and one shared SPF printing.

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 5 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: 프로필헵틸카프릴레이트, 폴리글리세릴-2다이폴리하이드록시스테아레이트, 폴리글리세릴-4아이소스테아레이트, 폴리글리세릴-6카프릴레이트, 폴리글리세릴-4카프레이트, 폴리글리세릴-10스테아레이트, 카프릴릭/카프릭트라이글리세라이드, 스테아릭애씨드
