Are you in search of a strong, yet gentle retinol product? The COSRX Real Fit Retinol Serum is infused with retinol derivatives that rejuvenate tired and dull-looking skin. Specially formulated with calendula extract, to help soothe redness and irritation (which is typically experienced with the use of retinol products). The result is a beautiful, glowing and flawless complexion!

Key features:

  • 0.5% retinyl palmitate (a derivative of Vitamin A/retinol) works to improve skin texture, while helping to treat the signs of sun damage, including wrinkles and hyperpigmentation.
  • Calendula officinalis extract is known for its soothing properties. Its addition to this serum helps to calm the skin and works well with retinyl palmitate. This combination of ingredients helps to make the formulation as gentle as possible!
  • Its lightweight texture absorbs rapidly into the skin and is great for those starting out with retinol, as it gently refines skin texture and diminishes the appearance of fine lines and wrinkles for firmer and younger-looking skin.

Size: 20 mL

Suitable for all skin types, particularly mature skin.


  1. Replace the cap with the provided dropper.
  2. After the toner step of your evening skincare routine, apply 2-3 drops to the face and neck, avoiding the eye area.
  3. Gently massage and tap to facilitate absorption.
  4. Follow with your favourite moisturiser.


  • Make sure to use adequate SPF protection during the day.
  • Do not use together with products containing Vitamin C, or exfoliating acids such as AHA and BHA, as this may increase the skin's sensitivity.
  • Contents may darken over time due to retinol's properties. This is a natural phenomenon that does not affect this product's potency.
  • Store in a cool, dark place and as far away from light and heat as possible.
  • Use within 3 months of opening.
