The Ordinary Retinol 0.5% in Squalane is a moderate-strength, water-free serum that reduces fine lines, wrinkles, and uneven skin texture while supporting hydration. Enriched with squalane, it minimizes dryness commonly associated with retinol use. Apply a few drops in the evening, avoiding other retinoids, for smoother, firmer, and more youthful-looking skin.
