COSRX - The Retinol 0.5 Oil Super Vitamin E + Squalane

COSRX The Retinol 0.5 Oil is a professional-grade anti-aging treatment formulated with a high concentration of 0.5% pure retinol to effectively target visible signs of aging. This nighttime facial oil combines the powerful wrinkle-reducing properties of retinol with deeply nourishing plant-based oils to deliver comprehensive skin rejuvenation while maintaining excellent skin tolerance. The advanced formula is specifically designed for users who have already built up retinol tolerance and are ready for more potent anti-aging benefits.
