IOPE Retinol Super Bounce Serum

Ingredient analysis and how the ad lines read

Read on 2026-09-25

What is this product?

A 50 ml entry-level retinol serum from Korean brand IOPE, sold as a daily, day-safe first retinol for pore sagging, firmness and fine lines. The 45-entry list is a light water and butylene glycol emulsion with squalane and a light silicone, carrying two retinoids: retinol, disclosed at 509 IU/g (0.015 percent), and hydroxypinacolone retinoate, plus peptides and madecassoside. There is no fragrance entry. No exfoliating acid; the acid-named entries are palmitic and stearic acid. It passed functional cosmetic review, with the function type not stated. Headline collagen and firmness figures come from in vitro tests; wrinkle figures come from a single uncontrolled human test.

What makes it different?

A low-dose retinol paired with hydroxypinacolone retinoate in a light emulsion, positioned by the brand as its mildest daily retinol below a stronger sibling serum, with morning use allowed alongside sunscreen.
