Anti Aging please

Hi This is my routine, well I am not actually using Dr Sam's flawless yet.

Are they any replacements I should use, I do not have sensitive skin, I like the sunscreen but is their something better, I would like to keep the richness of the cream.

My main concern is anti aging and to stop my skin from looking dull.

I do not have sensitive skin and am 56 years old....

Many thanks for any advice
