The Age You Started Using Wrinkle Cream

I'm twenty-nine. I have always been a little nervous about my skin aging. I was ten pleading to my mother to buy me wrinkle cream. Her with her hippie way of looking at make-up and face cream, she thought I was crazy. This is me though and I guess you have to be who you are... I know this happens to many of us but, I have people tell me I look eighteen. So what age did you start start using the miracles and who needs to?
