# Performance-Driven Retinol Serums IOPE Calls Attention to Two Expert Retinol RX™ Serums By Kalin Ned | Published 2026-09-24 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/expert-retinol References: [sephora](https://www.sephora.com/ca/en/product/expert-retinol-2-reti-jection-serum-P521632) & [sephora](https://www.sephora.com/ca/en/product/expert-retinol-1-super-bounce-serum-P521630)  [IOPE](https://www.trendhunter.com/trends/retinol-skincare-line), a clinical K-beauty brand with more than three decades of bioscience and dermatological research behind its anti-aging formulations, highlights the Expert Retinol RX™ 2% Reti-Jection Serum and the Expert Retinol RX™ 1% Super Bounce Serum. Both products reflect a broader shift in how retinol is being engineered and applied to skincare routines. Instead of competing on percentage alone, this serum pairs the brand's proprietary Expert Retinol RX™ 2% Complex with Reti-Jection™ technology, which uses three million [retinol-infused spicules](https://www.trendhunter.com/trends/smart-retinoid-serum) to encapsulate the active ingredient and carry it into the skin in a stable, controlled manner. These spicules are notably smaller than conventional versions and have been softened and polished along their edges. This makes the delivery process gentler while still supporting absorption and visible improvements in wrinkles, firmness, pore appearance, and radiance. IOPE's Expert Retinol RX™ 1% Super Bounce Serum boasts a lower concentration of Retinol RX™ alongside squalane for barrier support and hydration, plus [Hinoki](https://www.trendhunter.com/trends/hydrobiome-mist) Cypress Leaf Extract to soothe and balance the skin.
