Key Features at a Glance:

  • Potent 0.5% Pure Retinol: Unlike many products on the market, COSRX - The Retinol 0.5 Oil shuns the path of diluted efficacy; there's no purified water or derivatives here. Each drop delivers the full promise of 0.5% stabilised, pure retinol, plunging deep into the skin's layers to invigorate and renew from within.
  • Targeted Anti-Aging Care: Crafted to address the multifaceted signs of aging - from the loss of elasticity that gives our skin its youthful bounce to the dryness that etches fine lines and wrinkles deeper with each passing day. This oil is a clarion call for regeneration, beckoning your skin back to its days of vigour.
  • A Youth Booster for Seasoned Users: Specifically designed for those already inducted into the rites of retinol but requiring a higher concentration to breach the plateau of benefits their skin has grown accustomed to. It’s the next step in your retinol journey, propelling you towards the pinnacle of age-defying skin care.

How to use

For best results, integrate this retinol oil into your nightly skincare routine. Apply a small amount to cleansed and toned skin, avoiding the eye area. Make sure skin is dry before applying.

Given the concentration of retinol, remember to avoid daytime use and always apply sunscreen during the day when using retinol products in your skincare regimen.

To achieve the best results without overwhelming your skin, follow the step-by-step acclimatisation process. 

Initial Phase – Building Tolerance:

  • Limit usage to three times per week at night, eventually increasing to every other night as tolerated.
  • Evenly apply the oil over the face, neck, and areas with visible lines using your ring finger for delicate pressure.

Weeks 1-2 – Adaptation Period:

  • Apply every other night focusing on targeted areas such as under the eyes, around the mouth, the forehead, and neck.

Week 3 and Beyond – Full Integration:

  • Gradually transition to nightly application, spreading the oil to the entire face after cleansing and applying essence or serum.
  • Continue monitoring skin tolerance and adjust accordingly.


Every skin type is unique, and the tolerance-building phase may vary. If discomfort occurs, maintain the initial phase until the skin fully adapts. Over time, as your skin becomes more accustomed to retinol, you can safely increase the frequency and application area for more comprehensive benefits.
