The Ordinary Retinol 1% in Squalane is a highly-stable, water-free solution combining pure retinol with moisturizing squalane. This potent anti-aging serum helps reduce fine lines and wrinkles while promoting cell turnover for smoother, more youthful-looking skin. This product contains a high concentration of retinol (1%) which may cause sensitivity, especially when first starting use. It's recommended to begin with a lower concentration if you're new to retinol products. Apply a small amount in the evening and always use sunscreen during the day, as retinol can increase sun sensitivity. The squalane base helps minimize irritation while providing hydration. Store in a cool, dark place to maintain stability.
