Where can I see a product comparison of the major cosmetic companies product lines?

I want to see a chart or products review on skin care creams, mascara, and eyeshadow

There is a web site called Makeup Alley. The site is:
www.makeupalley.com

The reviews are user based. I don’t think this is the best site, but will tell you what you want to know about products by brand.

I hope this helps you!
