Meet Korea’s first stabilized 40% pure vitamin C cream. IOPE’s latest innovation is a high-performance brightening treatment that visibly reduces dark spots, evens tone, and restores radiance to dull, sun-damaged skin.

Formulated with 40% pure vitamin C and a potent blend of glutathione, ferulic acid, niacinamide, and resveratrol, this cream delivers next-level antioxidant protection. Clinical studies showed 400 hours of sustained antioxidant effects—double that of standard 20% vitamin C ampoules—with visible improvement in dullness, discoloration, and fine lines. The water-free formula prevents oxidation, keeping the vitamin C stable and effective from start to finish.

Developed through IOPE’s advanced dermatological research and backed by clinical testing, this formula is ideal for targeting pigmentation and boosting glow. Add it to your routine for bright, even, radiant skin.
