IOPE RETINOL SERUM IN GEL MASK

Ingredient analysis and how the ad lines read

Read on 2026-10-01

What is this product?

IOPE RETINOL SERUM IN GEL MASK (아이오페 레티놀 세럼 인 겔 마스크) is a single-use two-layer retinol sheet mask sold on the brand's own online store, with a banding gauze side and a collagen hydrogel side. Its printed list has 56 entries: water, glycerin and dipropylene glycol open it, niacinamide sits at 5th, adenosine at 26th, a retinoid ester at 46th and retinol at 47th, and a citric acid entry follows at 48th. The only printed amount is 23 ppm pure retinol in the last entry, beside a 1 percent formula figure in the copy. No fragrance entry or alcohol entry is printed, and the brand's wrinkle and pore figures are self-scored or unreconciled.

What makes it different?

A two-layer sheet mask built around a retinol and retinoid-ester pair, with one printed amount (23 ppm pure retinol) against a 1 percent formula headline the page never converts. The copy benchmarks it to the brand's own retinol serum and to an ultrasound home device, with self-scored test figures.

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 3 with no dictionary entry, left in Korean.

Worth a closer look

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