I can only use facewash since I crossed 23 age I can't put anything to my face , lightweight cream or serum, I get pimple, acne or anything small like anything caught in my face. I tried many dermatologist and they suggested cream , but that Light weight cream also makes my back like so many bumps .. I don't understand . What to do I can only use facewash other than only derma serus which doesn't cause me bumps and pimples and acne .. what to now , it's winter and my skin is very dry and bumpy but still I can't use anything.
