Here is a picture of the system :
The package of three runs about $50 but lasts a very very long time. Plus, if you are like me and love instant gratification it's totally worth it! I put the serum on before both the day and night cream after washing my face every morning/night. During the night I also seal the serum and night cream with a non-petroleum jelly from whole foods. This mixture feels kind of greasy but honestly does the best job of keeping moisture in, and preventing wrinkles and breakouts. As of now these are the only products I trust on my face all day long underneath makeup AND all night long soaking up moisture.
Do you have a favorite day/night cream?
What do you use to prevent wrinkles?
