COSRX The Retinol 0.5 Oil uses stabilized, pure retinol, not a diluted derivative, making it a genuinely high-strength anti-aging treatment. It's important to be upfront: this is intended for skin that already has some retinol tolerance, not a first-time retinol product.
Built to Support Skin Through the Process
Retinol can cause dryness or sensitivity as skin adjusts, so this formula pairs it with Squalane and Tocotrienol, sometimes called Super Vitamin E, to help protect the skin barrier while the retinol works.
What to Expect
With consistent use, pure retinol works to boost collagen production and skin turnover, helping smooth fine lines and improve firmness and tone over time. Results build gradually rather than overnight.
