"A powerhouse form of vitamin A, retinol encourages cell turnover, revealing healthier, softer skin while also tackling blemishes, dark spots and defying signs of ageing – including softening the appearance of fine lines and wrinkles and uneven tone. About this item Quantity: 30ml Effective anti-aging serum Gentle serum From the manufacturer The Ordinary Retinol 1% in Squalane This water-free solution contains 1% pure Retinol, an ingredient that can reduce the appearances of fine lines, of photo damage and of general skin aging. While Retinol is irritating to the skin and newer technologies exist that mimic the visible effects of Retinol without causing skin irritation. For this reason, we generally recommend using Granactive Retinoid 2% or Granactive Retinoid 5% instead of this formula. Caution: Retinol can cause significant irritation, redness and peeling, especially around the eyes and mouth, in the early stages of treatment while skin builds tolerance. If you have not used high-strength retinol formulas in the past, we strongly recommend that you start your retinol regimen with our Retinol 0.2% in Squalane and adjust to higher strengths of Retinol 0.5% in Squalane and Retinol 1% in Squalane as your skin builds tolerance. Directions: Apply a small amount to face in the PM as part of your skincare regimen, after water-based serums but before heavier treatments. Do not use with other retinoid treatments. Avoid unprotected solar exposure."
