Im 32 and only started wearing make-up in the last 2 years ...and even then, it isnt daily. Learned the basics from youtubers. Check out Kandee Johnson
(Kandee Johnson - YouTube) on youtube, she is a darling and really good at makeup tips.

I also learned a lot from experimenting. Most large chains offer "satisfaction guaranteed" so i have gone in and dropped 80$ on make up items i wanted to try out and then come back to actually return more than half od it when i figured out what actually worked for me.
