jenniferykandel has been using The Ordinary's products for the past year and has found them to be very effective. In the morning, they use the moisturizer and the buffet solution, which leaves their skin feeling refreshed, moisturized, and not oily. They also use the caffeine solution occasionally when they are tired and need to reduce dark circles. The argireline solution is light and helps with fine wrinkles on the forehead. The retinol is an oil that is soft and smooth and has changed the texture of their skin.
