I have been taking Retinil topically, a few drops rubbed over my face as a "serum". I don't know if it's my imagination, but my complexion looks better. No breakouts at all and decreased oil production. But not dry either - I don't need any moisturizer.
This might also be do to progesterone/pregnenolone I am taking also from Idea Labs... but those I'm putting on my body not my face.
Excellent! Thanks for sharing.
