Goodal Heartleaf Hyaluron Soothing Gel Mask

Ingredient analysis and how the ad lines read

Read on 2026-09-30

What is this product?

A single 43 g gel sheet mask from the Korean brand goodal, sold on the storefront of the brand owner group as a single sheet and a 5 sheet set. The 80 entry statutory list opens with water, glycerin, butylene glycol, cetyl ethylhexanoate and niacinamide, and carries a hyaluronic acid family, five ceramide entries, a houttuynia extract and four essential oil entries. It prints no fragrance or allergen entry, no ethanol entry and no exfoliating acid entry. The brand prints cooling, hydration and soothing readings from panels of 20 to 21 adults taken right after one use.

What makes it different?

A three piece gel sheet whose cooling capsule is footnoted as houttuynia extract and erythritol, over a hyaluronic family and five ceramide entries. Its trade-offs on the label: four essential oil entries, and percent improvement headlines that are indexes with pre-use set at 100 and come from single readings taken right after one use.

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.
