Supplements have been discussed. Just a quick word about any creams!
True, most of them are quite gimmick. From my point of view it's better to use more natural oils or butters. Shea butter, jojoba, almond, these all are great. I suggest to look up on comedogenic index regarding certain oils, especially if you have naturally oily skin that seems to clog up.
In my experience shea butter has been great on many levels.
If you can afford "more", then argan oil is fantastic stuff.
One member to my recollection did have a good run with the MaxOut serum but it's quite expensive. In the end it might not be that much addition to your routines. In MoS Shop there are few creams which are also proven effective.
It's just my personal choice to favor shea butter most of the time.
If you want a more PE suited lotion / oil or cream, consider making Essential Vein Oil.
One more item: Nigella sativa (black seed) oil is great stuff as well!
