although most of those creams dont work, put it on at night when you are relaxed and your body is regenerating.When is the best time of day to put on anti aging cream, im only 21, but its to prevent:)?
I agree that wearing at night is the best option after washing your face. Alot of them are great for acne too, I don't remember what it is but something in Oil of Olay cleared all mine up. So though it did nothing for age related wrinkles, it did keep the acne away.
