That’s *The Ordinary Retinol 0.5% in Squalane*, 30 mL/1 fl oz amber glass dropper bottle. *Short summary:* - *Use*: Mid-strength retinoid serum for anti-aging and skin texture - *Key actives*: 0.5% Pure Retinol + Squalane - *Claim*: Targets fine lines, uneven texture, and dullness by increasing cell turnover, with less irritation than 1% - *Texture*: Lightweight, anhydrous oil that absorbs slowly with a slight slip - *Best for*: Users who have already tolerated 0.2% retinol and want to level up. Good for normal, dry, or combo skin This is the middle step in The Ordinary’s retinol ladder: 0.2% ? 0.5% ? 1%. Squalane makes it more tolerable, but irritation can still happen. Use at night only on dry skin, 2-3x per week to start. Don’t combine with other retinoids, AHAs/BHAs, or pure vitamin C in the same routine. Daily SPF is mandatory while using retinol.
