COSRX THE RETINOL 0.5 OIL 20ML
Highly concentrated 0.5% pure retinol
No purified water or retinol derivatives.
Formulated using 0.5% stabilized, pure retinol for powerful anti-aging care.
Best for skin accustomed to retinol but still experiencing progressive signs of aging such as loss of elasticity and dryness.
For intermediate-level retinol users looking for a highly concentrated, youth booster.
I have not used this much but I have sensitive skin so I put the Mucin 92 Cream under it and Dear Klairs Vitamin E mask over it. No issues so far!
