The Ordinary Retinol 1% in Squalane 30ml DescriptionRetinol 1% water-free formulation contains 1% pure Retinol, an ingredient that can reduce the appearances of fine lines, of photo damage and of general skin ageing. Retinol 1% can cause significant irritation, redness and peeling in the first few weeks of use until the skin builds tolerance. These reactions are much stronger around the mouth and around the eyes. We would suggest using newer retinoid technologies such as that found in Advanced Retinoid 2% so as to avoid these unpleasant initial side effects. Ingredients: Cyclopentasiloxane, Caprylyl Methicone, Isoamyl Laurate, Ethyl Methicone, PEG-12 Dimethicone/PPG-20 Crosspolymer, Dimethicone/Vinyl Dimethicone Crosspolymer, Propanediol, Polysorbate 20, Retinol, Isoamyl Cocoate, Tocopherol, BHA, BHT. Directions:Apply a small amount to face in the PM as part of your skincare regimen. Do not use with other retinoid treatments. Use sun protection in the AM.
