Actually, eye cream is not a cosmetic product meant to be applied only at specific times. However, because it is quite oily, it is better to apply it in the evening rather than in the morning. It is said that if you apply it before bed, it prevents moisture evaporation while you sleep, keeping the eye area hydrated, and also helps your makeup adhere well without caking the next morning. Also, please note that it helps soothe the eye area irritated by UV rays during the day.
