COSRX The Retinol 0.5 Oil 20ml, 2-Pack

Features

COSRX The Retinol 0.5 Oil is a high-concentration, expert-level formula designed for intensive slow-aging care. This silky, lightweight oil absorbs easily into the skin, providing a radiant glow while targeting skin sagging, elasticity, and pore concerns. It is specifically formulated for those looking for a potent solution to improve skin texture and firmness.

Benefits

This oil helps normalize the skin's turnover cycle, resulting in a smoother and more refined complexion. It provides comprehensive care for skin elasticity, both on the surface and within, and aids in lifting care. Users may experience improved skin radiance and long-lasting moisture. Additionally, the formula helps address four key pore-related concerns, including pore volume, area, count, and depth.

Main Ingredients and their effects

Pure Retinol (0.5%): A high-concentration active ingredient that helps normalize the skin’s turnover cycle for a smoother skin texture and enhanced pore care. Squalane: A moisturizing agent that protects the skin from external irritation and harmful environmental factors. Tocotrienol (Super Vitamin E): Works in synergy with retinol to provide an elasticity-boosting effect, helping to firm and smooth the skin.

Clinical test results

Clinical trials conducted by the Derma Cosmetic Skin Science Research Institute (on adults aged 20–59) demonstrated significant improvements in pore conditions. Specifically, pore volume was reduced by 21.95%, pore area by 20.91%, pore count by 29.48%, and pore depth by 33.34%. Further assessments showed a 16% increase in surface elasticity and a 13% increase in deep skin elasticity. Additionally, 100% of participants in a 4-week consumer satisfaction study reported feeling that fine lines were alleviated, skin felt lifted and firm, and texture appeared smooth and moisturized. Evaluations also noted a 12.2% improvement in eye area skin angle, 10.3% in cheek area, 13.7% in mouth corner area, and 13.5% in jawline area.

Usage instructions

During the 1st and 2nd weeks of use (adaptation period), apply 1–2 drops to areas of concern only 2–3 times per week in the evening. From the 3rd week onwards (stabilization period), you may apply an appropriate amount to the entire face every other evening. After evening cleansing, apply the oil during the serum step. Dispense the oil onto your palms and use your fingertips to roll and absorb it into the skin, moving from the inside of the face outward. Please note that when retinol acts on the skin, temporary irritation such as redness, peeling, or stinging may occur; if irritation persists, reduce the frequency of use or discontinue use. Exercise caution when applying near the sensitive eye and mouth areas.
