COSRX - The Retinol 0.5 Oil 20ml

COSRX The Retinol 0.5 Oil is a concentrated night treatment designed to improve the look of fine lines, rough texture, enlarged-looking pores and loss of firmness. With 0.5% pure retinol, it offers a stronger step up for experienced retinol users, while a high level of plant-derived squalane helps keep the skin feeling soft and nourished. Tocotrienols and vitamin E provide additional antioxidant support, helping the complexion look smoother and more radiant over time. The silky oil texture makes it especially nice during cooler NZ evenings or whenever your skin feels dry but you still want focused anti-ageing care.

How to use: 

1. Use at night on clean, dry skin.
2. Apply 1–2 drops to your fingertips or palm.
3. Gently spread over the face, avoiding the eye and lip areas.
4. Follow with moisturiser.
5. Start 2–3 nights per week and gradually increase frequency as your skin builds tolerance.

Use sunscreen every morning. If you are new to retinol, a lower-strength formula may be a better starting point. COSRX recommends using this product within 3 months of opening.
