Please tell me about anti aging skin care products?

I am 42 years old and I want to know about anti aging skin care products. I want my skin to look young for long time and I don’t know which one to go for as all of them seem promising the same results. I don’t want to waste my money on useless products so please tell me if anyone has ever tried any anti aging cream and that has worked for you. I have normal skin so you can suggest according to it. Thank you.
