The Ordinary Retinol 1% in Squalane is a high-strength anti-aging serum that combines pure retinol with moisturizing squalane oil. This potent formulation helps reduce the appearance of fine lines and wrinkles while promoting cell turnover for smoother, more youthful-looking skin. This product should be introduced gradually into your skincare routine to allow your skin to build tolerance. Apply a small amount in the evening after water-based treatments. Due to retinol's sun-sensitizing effects, daily broad-spectrum sun protection is essential when using this product. Not recommended for sensitive skin or first-time retinol users. Store in a cool, dark place to maintain product stability.
