Here's one thing that worked for me:
Go easy.
I stopped buying commercial cleansers, serums, potions, you name it. Now, what do I use? Oils, water, my terrycloth wash towel. My skin has never been better, and I don't think I'll switch. I have sensitive skin, so I just rejected all the stuff that can be bought in a bottle at the store, and opted to use edible foodstuffs only. The best thing I ever did for my face. The only store bought thing I use, is baby/feminine wipes to remove makeup.
