Retinol 1% in Squalane offers a water-free solution containing 1% retinol—an ingredient that improves the appearance of fine and dynamic lines that arise from a loss of collagen and elastin, while evening skin texture and tone. What's more, this expert-level formula is supported with squalane, a moisturizing agent naturally found in your skin that enhances surface-level hydration and helps combat the dryness that can be associated with retinol use. The Ordinary Tip: Start with Retinol 0.2% in Squalane and slowly work your way up to Retinol 0.5% in Squalane and Retinol 1% in Squalane. That said, if you are prone to sensitivity, you may prefer to use newer retinoid technologies, such as those found in our Granactive Retinoid 2% Emulsion.
