IOPE RETINOL RETI-JECTION SERUM 50ml

Ingredient analysis and how the ad lines read

Read on 2026-09-22

What is this product?

A retinol serum pairing retinol (33rd) and hydroxypinacolone retinoate (35th) in a spicule carrier marketed as Retinol RX 2%, with printed pure retinol content of 880IU. Choose it for a firmness- and pore-focused retinol step; expect a fragrance-free formula with niacinamide high in the list but with no disclosed retinol percentage beyond the IU figure.

What makes it different?

The formula places retinol late (33rd) with hydroxypinacolone retinoate (35th), a gentler retinoid ester, rather than leading with retinol. Niacinamide sits seventh, unusually high, alongside panthenol and shea butter for a cushioned texture. The page names its testing institution and gives a 4-week, 32-person study window, though full protocols are not printed. No fragrance ingredient and no drying alcohol appear in the list.

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 2 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.

We could not place these in the list above: 시어버터, 돌콩오일, 레티놀, 하이드록시피나콜론레티노에이트

Did the ad claims hold up?

We checked 8 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.
