The SERUM is a highly concentrated, potent anti-aging treatment with 0.5% pure retinol, formulated to target deep wrinkles, fine lines, and loss of skin elasticity. It is specifically designed for intermediate to advanced retinol users. 

Key Ingredients & Benefits
The oil combines pure retinol with ingredients that enhance its efficacy while minimizing irritation and dryness: 
  • Pure Retinol (0.5%): A powerful form of Vitamin A that accelerates collagen production and skin cell turnover to visibly reduce signs of aging and improve skin firmness.
  • Squalane: A plant-derived oil that deeply hydrates the skin, protects the skin barrier from external irritation, and prevents moisture loss.
  • Super Vitamin E (Tocotrienol): Works synergistically with retinol to provide high antioxidant protection, reducing visible signs of aging and skin damage. 


Effectiveness & Reviews
User reviews and expert opinions highlight the product's effectiveness and gentle formulation for a potent retinol product:
  • Visible Anti-Aging Results: Users report noticeable improvements in fine lines, wrinkles, and skin elasticity, with some seeing a lifting effect in as little as four weeks.
  • Improved Pores and Texture: The oil helps refine pores and smooth skin texture, leaving the complexion "silky" and radiant.
  • Minimal Irritation: Despite its high concentration, many users with sensitive skin experienced minimal to no irritation, redness, or dryness, a significant plus compared to other retinol products.
  • Lightweight Texture: The silky-smooth oil formula absorbs effortlessly without leaving a greasy or heavy residue. 

How to Use
The COSRX The Retinol 0.5 SERUMis for nighttime use only. An adaptation period is crucial to build skin tolerance. 
  1. Cleanse and Tone: Apply 1-2 drops to the face during the serum or moisturizer step of your evening routine.
  2. Start Slowly: For the first two weeks, use only 2-3 times per week. Focus on areas of concern initially (forehead, under eyes, mouth, neck).
  3. Gradual Increase: From the third week onwards, you may gradually increase the frequency to every other night, or every night if your skin tolerates it well.
  4. Sun Protection: Always use a broad-spectrum SPF 30 or higher sunscreen the following morning, as retinol increases sun sensitivity.
  5. Storage: Store the product in a cool, dry place, or ideally a refrigerator, away from direct sunlight, heat, and oxygen to maintain ingredient efficacy.
