Skinceuticals C E Ferulic Professional Size - 60ml / 2oz
Product Description IMPORTANT INFORMATION REGARDING THE COLOR OF YOUR C.E.FERULIC: When very fresh = recently manufactured, the C E Ferulic is a very clear liquid. It turns yellow with exposure to heat, light and air, so this does definitely NOT mean that the product is old or expired (unless it is very dark). The samples vials AND the full sized bottles all turn yellow and then even orange if you keep them long enough. You can STILL use them at this stage. This means the vitamin C and Ferulic acid are oxidized. To keep them clear as long as possible, we suggest you keep them in the refrigerator (like all vitamin C skincare products). This will keep them clear and ultra fresh, thus useable for a longer period of time. Most of Prestige-Beautica's Ferulic will arrive to you totally clear because none of them stays long enough on our shelves.
