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 intermediate 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. How to use: Apply a few drops to the face in the evening. Do not use with other retinoid products. Use sun protection during the day. Caution: Retinol can cause irritation, redness, and peeling, especially around the eyes and mouth, in the early stages of use while skin builds tolerance. If irritation occurs, rinse off, cease use. Patch testing prior to use is advised. Keep out of reach of children. Don’t use it if you are pregnant or breastfeeding.
