Products that make you look good?

I'm no plain jane, as I've gone to modeling school and all that (not homely looking) but I want to look super cute and attractive. I'm really petite, but curvy. I'm in my mid 20s. What sort of products should I be trying out? I use name brand products like Estee Lauder, Pureology, Paul Mitchell, and that sort of thing. Should I be trying an anti aging regimen? I feel so uncomfortable around other girls who look better than I, or other older relatives who look younger.
