Yes, moisture cream then La Base Pro. That will help set your makeup for the day. There is an eye shadow base that also help holds eye shadow in place as well. I use them both and love it. PS it takes a very very small amount of each.
Not in my opinion I have used for 32 years I feel there is a proper moisturizer for each decade I use everything to provide max moisture and smoothness with the Absolue line. The eye genifique is fantastic as well as the colors are always updated.
It is never to early to start, however after using this product I feel it really adds more moisture for my dryer skin. I hope this helps. I have used Lancome for 32 years and people never guess my age.
