The brand’s essence
Retinol
The essence is grounded in Super Bounce Serum’s retinol and retinoid Retinol RX formula. A pale yellow cream-serum swatch represents its texture; the RX percentage does not mean pure retinol concentration.
Origins and history
IOPE began in 1996 as Amorepacific’s research-led skincare brand. Work on difficult-to-stabilise ingredients shaped its identity. Retinol’s sensitivity to light, heat and oxygen made manufacturing and packaging part of research alongside ingredient selection, with protection inside the finished product becoming a central question.
Retinol 2500, introduced in 1997, became a defining product; the official timeline also records stabilised vitamin C in 1998. Research later extended to protective structures and processes limiting oxygen exposure. A PDRN serum in 2022 and the XMD family in 2025 marked expansion into new ingredient areas.
IOPE entered the US through Sephora in March 2026, presenting retinol, vitamin C, PDRN and XMD products together. This range made the breadth of its development visible. Its identity continues through reformulating selected ingredients across generations and translating them into new experiences.
