Why does the skin on my forehead look shiny and crinkly? (Photo)

Try not to let your perfectionistic side drive you insane!  No matter what you do, you will have some changes in your skin.  Some of these will be absolutely unavoidable.  Protect your skin from sun damage with the use of a hat or sun screen.  Best.

I applaud your efforts for skin care.  The bottom line is that you should be seen by a skin care specialist- many are associated with plastic surgery offices so all of your care can be under one office.  These teams will really optimize a treatment regimen best suited for your skin and goals.  In general, however, I will say that for excess oil (perhaps this is what you mean by shiny) a gentle cleanser, salicylic acid pads, tretinoin, and sunblock are key. 
Not everyone is a good candidate for this treatment so please see a Board Certified or Board Eligible Plastic Surgeon to evaluate if you may benefit. Good luck!
