Features

COSRX The Retinol 0.5 Oil 20ml, 2 Pieces is an intensive facial oil designed for experienced retinol users seeking concentrated slow-aging care. Formulated with 0.5% pure retinol, this facial oil delivers high-potency skin care in a lightweight, silky oil formula that absorbs smoothly into the skin without feeling sticky. It works to restore a youthful glow, improve skin texture, and promote a firmer, smoother appearance.

Benefits

This silky facial oil provides multi-action skin enhancement by addressing visible signs of aging, elasticity loss, and enlarged pores. It helps smooth rough texture, improves both surface and inner elasticity, and boosts skin radiance for a healthy, glowing complexion. The nourishing formula provides deep hydration while caring for sagging skin, fine lines, and stretched pores to maintain a firm, refined skin appearance.

Main Ingredients and their effects

Pure Retinol (0.5%): A highly concentrated form of active retinol that normalizes slowed skin turnover, smoothes rough skin texture, and provides targeted elasticity and pore care for experienced users.

Plant-Derived Squalane: Offers rich moisturizing benefits and protects the skin from external irritants while enhancing overall softness and smoothness.

Tocotrienols (Super Vitamin E): Works synergistically with retinol to enhance skin elasticity and provide antioxidant benefits that foster a vibrant, firm complexion.

Clinical test results

Human application tests demonstrate significant visual improvements in skin aging indicators and pore structural attributes. In clinical evaluations, participants showed a 4% improvement in the overall skin aging index. Clinical measurement of pore characteristics recorded a 21.95% reduction in pore volume, a 20.91% reduction in pore area, a 29.48% reduction in pore count, and a 33.34% reduction in pore depth. Further testing demonstrated a 16% increase in surface skin elasticity, a 13% increase in deep elasticity, alongside facial angle lifting improvements across the eye area (12.2%), cheek area (10.3%), mouth corners (13.7%), and jawline (13.5%). Skin irritation testing and primary irritation tests on sensitive skin types have also been completed.

Usage instructions

Incorporate COSRX The Retinol 0.5 Oil into your evening skincare routine at the serum stage. Dispense a few drops into the palm of your hand and gently roll over the face from the center outward using your fingertips until absorbed.

During the initial adaptation phase (weeks 1 to 2), apply 1 to 2 drops onto specific areas of concern 2 to 3 evenings per week. Once your skin adapts (week 3 onwards), transition to using an appropriate amount over the entire face every other evening. Retinol may cause mild temporary redness, peeling, or a tingling sensation. If irritation persists, reduce application frequency or discontinue use. Exercise caution around sensitive areas near the eyes and mouth.
