Recommendations when using Retinol

• Start with using a very small amount and gradually increase amount and frequency of usage.
• Avoid using Retinol with products highly concentrated in acidic active ingredients such as Vitamin C, AHA and BHA.
• Do not use physical scrubs, peeling products and beauty devices when using Retinol to prevent skin irritation.
• Due to the nature of the ingredient, irritation may occur. If irritation persists, reduce frequency of use or stop using the Retinol product.
• If excessive skin peeling or skin troubles appear, stop using the Retinol product
• As Retinol makes skin more sensitive to ultraviolent light, please use sunscreen after use.
• As Retinol ingredients are sensitive to light, heat and air exposure, please store the product in a cool place away from direct sunlight.
