The Ordinary Retinol 0.5% in Squalane is a moderate-strength retinol serum formulated to target signs of aging. This water-free solution combines pure retinol with moisturizing squalane to help improve skin texture and reduce the appearance of fine lines while minimizing potential irritation. This product should be applied in the evening as part of your skincare routine, after water-based serums but before heavier treatments. Start with a small amount and gradually increase usage as tolerance builds. Due to retinol's sensitivity to UV exposure, sunscreen use during the day is essential. Not recommended during pregnancy or breastfeeding. The formula contains squalane, jojoba seed oil, and other botanical extracts to support the retinol's effectiveness while maintaining skin comfort.
