The Retinol 0.5 Oil

COSRX The Retinol 0.5 Oil 20ml combines 0.5% pure and stabilized retinol with squalane and vitamin E in an advanced formula that both treats and protects the skin. Retinol, one of skincare's most proven ingredients, stimulates cell renewal and collagen production, gradually making the skin smoother, firmer, and more resilient. At the same time, squalane and vitamin E help counteract irritation and maintain the skin's moisture balance, making even a higher concentration feel more controlled and balanced on the skin. The result is a treatment that not only addresses signs of aging but also improves the skin's texture, tone, and radiance over time. :contentReference[oaicite:1]{index=1}

The skin appears smoother, plumper, and more elastic with a clearer radiance and a refined texture that gives a stronger, more youthful overall impression.

Directions for use:
Apply 1–2 drops to your evening routine. Start 2–3 times a week and gradually increase. Always use sunscreen during the day.
