What are the best beauty tips to achieve babyskin?

Okay, so before i used to have baby soft skin. I would get complimented on it alot, and before i used aveeno. It lightened my skin and made it so soft. But ever since i've been moving around alot, switching schools. and even getting kicked out. I've been having too much stress. and now my face has dry patches. and it's kind of bumpy. I do know alot about skin and i've tried so much stuff. My skin is dry too but before i know how to fix that. Now it seems impossible. Help anyone?
