The Ordinary Retinol 1% in Squalane is a potent anti-aging serum that combines pure retinol with moisturizing squalane. This highly-stable, water-free solution helps reduce the appearance of fine lines and wrinkles while promoting cell turnover for smoother, younger-looking skin. This product contains a high concentration of retinol (1%) and should be introduced gradually into your skincare routine to minimize potential irritation. It's recommended to use it in the evening and always follow with sunscreen during the day, as retinol can increase skin sensitivity to UV rays. The addition of squalane helps maintain skin hydration and reduce potential dryness associated with retinol use. Store in a cool, dark place to maintain product stability.
